Room thermostats for heating and cooling
RAA.. – analog room thermostats
The RAA.. room thermostats are tailored to maintain the required room temperature for both heating and cooling systems. They offer 2-position control with a 2-wire connection and acquire the room temperature by means of a gas expansion diaphragm.

RAV.. – self-learning room thermostats
The RAV.. room thermostats are ideal for customers looking for an analogue design combined with the very best in comfort and energy saving. The patented self-learning two-position algorithm providing PID control has the flexibility to operate in the most demanding temperature control applications.
Typical use
Solenoid valves of instantaneous water heaters
Solenoid valves of atmospheric gas burners
Forced draught gas and oil burners
Circulating pumps in heating systems
Electric direct heating
Fans of electric storage heaters
Zone valves (normally closed)

RDG.. – room thermostats with large LCD
The RDG.. room thermostats are very versatile. Thanks to their large display and intuitive operating concept with setting knob and large buttons, the units are extremely user-friendly and the backlit display even allows the unit to be operated in the dark. The required application can simply be selected via DIP switches before mounting the unit. The RDG.. use for the room temperature control either a 2-position, P or PI algorithm.
Typical use
Control of chilled or heated ceiling with electrical heater, radiator or floor heating
2-stage heating or cooling applications
Additional function like remote temperature sensing for return air control, operating mode switch-over to command energy saving mode, floor temperature limitation, dew point monitoring etc.
