Applications
The thermostats support the following applications, which can be configured using
the DIP switches at the rear of the unit or a commissioning tool.
DIP switches 1...3 need to be set to OFF (remote configuration, factory setting) to
select an application via commissioning tool.

*) With PWM control, it is not possible to ensure exact parallel running of
more than one thermal actuator.
If several fan-coil systems are controlled by the same room thermostat, preference
should be given to motorized actuators with On/Off or 3-position control.
Note:
For the parallel operation of the actuators, refer to information in the data sheets of
the selected actuators and to this list, depending on which value is lower:
Maximum number of actuators in parallel on the RDG100KN
•max 6 SS…31.. actuators (3-pos)
•max 4 ST…23.. if used with On/Off control signal
•max 10 SFA.., SUA.., MVI.., MXI.. On/Off actuators
•Parallel operation of SQS35 is NOT possible
Maximum number of actuators in parallel on the RDG160KN
•max 10 SS…61.. actuators (DC)

Mechanical design
The room thermostat consists of 2 parts:
•Plastic housing with electronics, operating elements and room temperature
sensor
•Mounting plate with the screw terminals
The housing engages in the mounting plate and is secured with 2 screws.
1) Operating mode button / Esc
2) Fan mode button / Ok
3) Rotary knob to adjust setpoints and
parameters
