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).
