Operation
The room thermostat is based on a two-wire, gas membrane technology.
When the room temperature falls below the selected setpoint, the thermostat closes the
heating contact. If the room temperature is over the selected setpoint, the cooling
contact is closed.
Adjustments
A rotating setpoint adjuster inside the thermostat can select the required temperature.
•
RAA10… No adjustments can be made outside the thermostat. The cover must be
removed to adjust setpoint.
•
RAA20… High and low setpoint limit stops can be engaged to limit temperature
range.
