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.

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 operature 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.

Features:

• Accurate PWM-control;

• Compatible with 3’rd party wall frames;

• Shine through display with mode keys;
