DEVIwet™ 230V room thermostats for hydronic floor heating

Description

DEVIwet™ Dial

DEVIwet™ Display/Programmable

DEVIwet™ is a range of room thermostats for hydronic floor heating applications.

The thermostats are mains powered and can be used as a stand-alone thermostats or in combination with wiring center 088H0016.

DEVIwet™ can control up to five thermal actuators and comes in three versions:

•DEVIwet™ Dial: uses a relay output. The room temperature is set with the dial in a range from 5 to 30 °C. The dial can be removed, allowing limitation pins to be used to limit the setpoint range.

•DEVIwet™ Display: uses a triac output. The room temperature is set in a range from 5 to

35 °C via a “touch on glass” interface with a shine through display. The display is “OFF” in normal operation.

•DEVIwet™ Programmable: uses a triac output. The room temperature is set in a range from 5 to 35 °C via a “touch on glass” interface with a shine through display. The display is “OFF” in normal operation. The user can choose between 7 pre-defined heating schedules. A schedule can be temporarily overrided by using the three mode keys. The thermostat can also operate without scheduling (constant room temperature setpoint). The thermostat uses forecast (adaptive learning).
