Weekly digital programmable thermostat for greenhouse

This device is a weekly digital programmable thermostat powered with 230V , for room temperature control on three stages (Comfort, Economy or Off/Antifrost) which allows to manage, on full automatic mode, double-power version devices, double-stage and one-stage, with the possibility to activate the second stage at the same time with the first one for a maximum of 200 seconds.

A third relay output is available and managed only in cooling mode, for the activation of a fan.

Furthermore this device is featured with a reset circuit for burners with block signaling and reset button, electrically separated from the programmable thermostat. This device can be used either on heating and cooling systems. The programmable thermostat is featured with a wide backlit display in order to view all the operational conditions, the hourly set program, room temperature detected by the external sensor or, if chosen, the current time. It offers the possibility to set up to 7 different programs, one for each week day, with minimum intervention time of 1/2 hour within 24 hours.
