comfort mode is activated (by pressing the moon symbol) the set
temperature will be 17
°
C (default).This function can be activated
by the room thermostat (default) or via a master thermostat or the
building management system.

Heating/cooling mode changeover
This function changes the complete heating/cooling system from
one mode to an other. If the heating system is a four pipe
system then all connected zone valves will controlled via the
WTC-3. This function can be activated only on the master

Built in humidity sensor
Every DRT-200 room thermostat has a built in relative humidity
sensor. This sensor continuously measures the relative humidity in
the room and sends information to the WTC-3 base unit. In case
of high humidity the WTC-3 will adjust the set temperature of
thermostat increasing it step by step.
4.4.6.
Open window detection
Each thermostat has an open window detector input. If this is
used with a window sensor, then the thermostat will stop the
heating/cooling system if the window is opened.

Dew point sensor connection
Each thermostat has a dew point sensor input. This sensor is
installed in the ceiling operates as an override if the sensor
detects condensation; the thermostat closes the actuator on the
manifold, stopping the cooling in the room.
4.4.8.
Dimmer function
The thermostat continuously measures the brightness of the envi-
ronment, and sets the LED s brightness accordingly. This ensures
a higher comfort level as the LEDs dim in low light condition.
