Ordering
Danfoss Icon™ is a range of flush and surface
mounted room thermostats for hydronic floor
heating applications.
Danfoss Icon™ Programmable is mains powered
and can be used as a stand-alone thermostat or in
combination with wiring center 088H001600.
The thermostat uses a triac output and can control
up to 5 thermal actuators.
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).
The thermostat uses a “touch on glass” interface
with a shine through display. The display is “OFF” in
normal operation.
Product Version Size For junction box Code no.
