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
