It is the ambient temperature desired during the set times of heating operation, normally defined as daytime.

It is the minimum ambient temperature desired during the heating Reduced time, normally defined as night-time.

The antifreeze function allows a minimum temperature to be selected and maintained when the programmable thermostat is switched off, so that the unit is protected if the ambient temperature drops below zero.

The difference between the set temperature and the boiler’s ignition temperature is called the hysteresis (or differential). In digital thermostats, hysteresis is typically 0.2° C and is sometimes adjustable by the user. In analogue thermostats, hysteresis is typically 0.4° C. This function prevents damage resulting from the boiler being switched on and off too frequently.

It often happens that the thermostat has to be installed in places defined as being “unhappy” - for example near sources of heat, drafts or particularly cold walls (thermal bridges). This implies the detection of an errant temperature compared to the actual temperature of the environment. In such cases, the option for adjusting the Offset comes in very handy. This parameter allows the temperature detected by the internal sensor or remote probe of the thermostat to be offset in order to correct any systematic reading errors due to the positioning of the programmable thermostat in an area that is likely to affect proper operation. 

The Set Point temperature represents the target the user wants to reach through programming the thermostat to obtain the greatest comfort inside the home. 

The product label bears information about the week (the first two digits) and the year of production (the last two digits). For example, 4414 indicates week 44 of 2014. The warranty period is 36 months from the date of production.

The simplest cause is the temperature in the house falling below the set Reduced temperature. If the left dial with the Moon is set, for example, to 18° C but the home temperature - often without our knowledge - is lower, the heating will activate. If not, please contact our support service and we will be happy to conduct tests with you. 

Daylight Saving Time may not have been changed and thus there is a lag between the pins and the current time. Check that the time corresponds to the time slot of the pins. If not, you can adjust the clock of your Freetime Plus by following these simple steps:

1. Open the cover on the battery compartment;
2. Press and hold down the OK button for at least 3 seconds;
3. Adjust the time with the G and H buttons;
4. Confirm with the OK button;
5. Adjust the minutes with the G and H buttons;
6. Confirm with the OK button.

The Freetime Plus programmable thermostat pins are deliberately tough so as to avoid accidental movement when cleaning the device, for example. Considering that moving the pins is not, in most cases, a daily operation, a small screwdriver can be used to move the pins if necessary. 

For space reasons, the first pin of the Freetime Plus model refers to the time interval between 12:00 am and 5:00 am. For this type of programming, a different model should be installed - the Magictime Plus, Freetime Evo, Wi-Time or Bluetime.

It is possible to connect several DRR01M radio receivers to a single wireless programmable thermostat. Simply activate the “Test Radio” function on the programmable thermostat for the time necessary, pressing the button so that the additional receiver can learn the radio address of the transmitting programmable thermostat.

No, you can buy either the programmable thermostat or the receiver. The only necessary operation will be to repeat the association between the old component and the new one.  

An Internet connection is essential to complete the initial configuration and commissioning of the programmable thermostat. The operations to be performed are:

• Download the Seitron Smart App on your smartphone;
• Register as a “New User” by entering an email and password;
• Pair the programmable thermostat and apps via a Wi-Fi network;
• Set the operating mode of the programmable thermostat. 

However, if Remote Management from the app is not a priority, the main features of the programmable thermostat can also be managed offline:  

• Power on and off;
• Increase or decrease the set point temperature using the specific arrows. Pressing the arrows further activates manual mode;
• From the main menu, the basic parameters antifreeze, Offset and hysteresis can be adjusted, the lighting and language settings can be managed, the Infoservice can be accessed and the heating or cooling mode of operation can be selected.

The weekly schedule and Boost Mode are only adjustable via the app. 

No, the only limit is the memory of the smartphone used.

Of course! With the Seitron Smart App, you can create different spaces and assign a name of your choosing (such as “House by the sea”/“House in the mountains”). The number of houses that can be managed is potentially infinite.  

Yes, if the system has several heating circuits (such as on the first and second floors). Each zone will need to be regulated by a different Wi-Time programmable thermostat. Each has its own IP address and, of course, each device will operate its own zone valve or circulator.

No - potentially, there is no limit. 

No - potentially, there is no limit. 

Yes.

To keep up-to-date, we recommend checking backward compatibility directly from the Play Store or Apple Store. 

Once saved, the programme is maintained and continues to run even offline. However, you will not be able to access the information in the “Chart” section via the app.

That will not be necessary. Once power is restored, the programmable thermostat will resume normal operation.

At the moment, Wi-Time is only via wiring. You have to connect to the standard two wires just like any programmable thermostat. We are working on this with you in mind!  

We purposely set the Wi-Time so that during normal operation, it sends a signal every 5 minutes. If the programmable thermostat loses connection to the Wi-Fi network, it will try to restore it by sending a signal every 2.5 minutes. This differentiates us from other devices designed for home automation. 

One of the main differences between the 2.4 GHz and 5 GHz Wi-Fi frequency is the bandwidth, which affects the distance covered by the wireless signal. The 2.4 GHz frequency has a wider range of action and as a result, the range of the Wi-Fi signal with a 2.4 GHz Wi-Fi network is greater. It is thus advisable to turn on the Wi-Fi at a frequency of 2.4 GHz on your router if the signal of your Wi-Fi network covers a large area, as one’s home may be. 

A two-phase power supply is no problem, provided that it remains within the power supply limits indicated in the technical characteristics (100..253 Vac 50..60 Hz).

Not at the moment but it may well do so in the future.

The gas detector, also referred to as an “electronic nose”, is a device for domestic or industrial use tasked with signalling any anomalies arising from exceeding the tolerance threshold of a gas in the environment. In the home environment, methane (93% of the national consumption) and LPG (Liquefied Petroleum Gas) are gases closely tied with daily operations such as cooking or domestic heating.

The gas detector contains a sensor, the most delicate and important part of the appliance. The sensor is specially calibrated for precise sensitivity in order to monitor gaseous substances that exceed the safety threshold, always remaining below the Lower Explosive Level (LEL). If the threshold is exceeded, the detector will emit a visual and audible alarm to warn of imminent danger. If the system is equipped with a solenoid valve, the device can act on the latter, ordering the shutoff with a consequent interruption of the gas flow. 

To date, a gas detector inside the home is not legally mandatory. Pursuant to Ministerial Decree 37/2008, a qualified installation technician must issue a declaration of the gas system conformity, specifying the material and appliances used, with particular reference to the tubing. Having determined the suitability of the system, it is also true that the gas commonly used in the home is odourless by nature and is thus subjected to an odourisation process by the distributors so that the user can immediately detect any leaks. However, this reasoning is only valid in contexts monitored around the clock. At night or when you are away from the house, the presence of harmful substances is almost impossible to detect. It goes without saying that a gas detector offers the best protection for the entire family, the home and the safety of others.

To install or replace the gas detector, simply contact your trusted electrician or plumber. Ensure they are: 

• familiar with the installation, assembly, commissioning and maintenance of the product; 
• aware of the regulations in force in the region or country regarding installation and safety; 
• have first aid training.

The speed of the apparatus’ operation is closely related to its location in the environment and the type of gas to be detected. 

A methane gas detector must be installed 30 cm from the ceiling, given that methane is lightest than the air. 

The LPG gas detector, on the other hand, must be installed 30 cm from the ground since propane is a heavier gas than the air and tends to settle. 

Being able to sense both ‘lightweight’ methane gas and carbon monoxide (being slightly lighter than air, having specific weight of CO = 1.15 kg/m³ and the specific weight of air = 1.2 kg/m³), it is recommended that the CO detector be installed up high at about 30 cm from the ceiling. 

In any case, it is a good idea not to install the detector in any locations where functionality might be compromised, such as: 

• in an enclosed space (such as inside a wardrobe or behind a curtain); 
• directly above a sink; 
• above or near the hob; 
• near a door or window; 
• near an air extractor; 
• in an area where the temperature may fall below -10° C or exceed +40° C; 
• in a place where dirt and dust can block the sensor;  - in a damp room. 

At least once a year.

The calibration of the sensor cannot be altered. Calibration is fixed and complies with the European UNI CEI en 50194-1:2010 standard. The sensors installed in the latest models of gas detectors have a zeolite pre-filter positioned in front of the sensor, which greatly limits false alarms due to the presence in the air of substances with gas-like molecules. However, it is good practice to avoid using the following substances in the vicinity of the gas detector:

• Acids
• Petrol
• Alcohol
• Solvents
• Glues
• Diluents
• Silicone products in general
• Detergents
• Perfumes
• Spray in general

A solenoid valve is a device for controlling the flow (On-Off) of liquids or gases. The fields and types of application are innumerable, depending on the nature of the feeding, the shape and balance (monostable or bistable).

Solenoid valves for gas control are comprised of:

• A membrane - raises and lowers to open or close the passage;
• A solenoid valve - when the electromagnetic coil is crossed by the power, it induces the displacement of the membrane (opening or closing the passage).

Solenoid valves are constructed so as to ensure the interception of the gas both when the alarm signal comes from the gas detector and in the event of a lack of electricity. In both cases, the shutter fitted in the valve is released and blocks the passage of fuel. Once the gas leak has been eliminated or the electrical network has been restored, to return the valve to the open position, the user must act manually by lifting the dial located above the solenoid valve tube. 

The Ministerial Decree 12/04/96 concerning “Approval of the technical regulations on fire prevention for the design, construction and operation of heating systems fuelled by gaseous fuels” applies to installations of new construction and requires the gas solenoid valve to be fitted in systems with:

• Thermal flow greater than 35 Kw
• Gaseous fuels
• Max. gas pressure 0.5 bar

If the surface area of the compartment in which the gas unit is installed is at an altitude of -5.0 to -10 m from the plane of reference, a solenoid valve is mandatory. In this case, a Normally Closed solenoid valve must be installed externally on the gas supply line. 

Let us first understand the difference between the two types of solenoid valve:

• N.O. (Normally Open) - in a state of rest, hence without any power supply, it allows the passage of gas. 
• N.C. (Normally Closed) - in a state of rest, hence without any power supply, it does not allow the passage of gas.

Current applicable legislation does not impose any restrictions on choice in this regard, hence it is at the discretion of the installer/customer. 

The substantial difference is that the Normally Closed solenoid valve is “intrinsically safe” since it ensures - even in the absence of power and thus with a non-functioning gas detection system - the closure of the gas line. 

Calibration is the operation that defines the metrological characteristics of a device by comparison with a sample, being an instrument that refers to the International System adopted as a reference. This procedure photographs the current state of the instrument without acting on the adjustment or tuning of the instrument. The calibration checks the degree of accuracy or error, being the level of correspondence between the value of the sample and the value measured by the instrument. 

Adjustment improves the accuracy of the device, which is aligned in order to reduce measurement deviations to a minimum. The adjustment methodologies are multiple, however they have a common starting point: the calculation of the accuracy error is based on comparison with the measurement of reference of the sample instrument with the value indicated by the operating instrument to be adjusted. 

The UNI 10127-2 standard (“Guide for the definition of measuring instruments calibration intervals - Advised interval for measuring instrument used for geometrical, angular and linear dimensions”) provides some references for the choice of calibration operation, based on the type of instrument. It is in any case advisable not to exceed three years. 

In addition to this Directive, there are several factors to consider: 

• The type of instrument;
• The frequency of use;
• The storage and preservation conditions;
• The methods and environmental conditions of use;
• The degree of accuracy of the desired measurement;
• The frequency of maintenance and tuning;
• Any impacts, falls or mechanical, electrical or thermal stresses;
• Directions and suggestions provided by the manufacturer.

There are 3 good reasons:

1. Optimal functionality that ensures high performance and consistent quality without errors;
2. The limitation of waste and eventual disputes from customers;
3. Suitability for use in process measurement and control.
