6. Product description
The DuoFern Room Thermostat 2 automatically measures and
controls the room temperature in individual rooms, e.g. by
controlling a radiator, the floor heating or air conditioning.
The temperature is either measured by the built-in sensor or by
the optional external Remote Sensor 9485-F. The room thermostat
has a potential-free relay output.
Support for three heating modes
The DuoFern Room Thermostat 2 can be used and
configured in three different heating modes, see page 82:
◆ Room temperature controller
◆ Room temperature controller with limiter function
◆ Cooling function
Furthermore, the DuoFern Room Thermostat 2 can be combined
with the DuoFern Radiator Actuator 2 (item no. 3500 30 74, type:
9433-1) to control it.
Setting multiple heating phases
Up to six heating or cooling phases (incl. four target temperatures)
can be set for each day.
Setting heating phases centrally in the HomePilot® or
locally in the DuoFern Room Thermostat 2
The desired use is carried out by selecting the corresponding
DuoFern mode in menu 9.9.2, see page 108.
