Danfoss Icon™ Programmable

Room Thermostats, 230 V

Description

Danfoss Icon™ Programmable 088U1021 Danfoss Icon™ Programmable 088U1025

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.
