The Siemens RAA11 room thermostat is a tamper-proof mechanical device designed for on off temperature control in heating-only or cooling-only systems. The setpoint is not accessible from the outside, making it suitable for applications requiring controlled temperature management.
Operation is based on a gas-filled diaphragm that senses room temperature. When the temperature falls below the setpoint, the heating output closes; when the temperature exceeds the setpoint, the cooling output closes. Heating and cooling outputs are separate.
