Presence detector
This sensor should be ceiling-mounted and detect slight movements, such as a person typing
on a keyboard.
Control sequences
Temperature control
The thermostat acquires the room temperature via the built-in sensor and maintains the
setpoint by delivering actuator control commands to the heating and/or cooling equipment.
Outputs are available to control:
• Fan: 1-speed, 3-speed fan or DC 0...10 V
• Heating/cooling coil, radiator, electric heater
• Compressor: 1-stage, 2-stage
Humidity control
The thermostat acquires the room humidity via the built-in sensor and limits the humidity
in the room according to the selected setpoint (minimum/maximum) either by shifting the
temperature setpoint, or by enabling outputs to release the external equipment as needed,
e.g. the dehumidifier or humidifier.
Humidity control is active in Comfort mode and disabled in Economy or Protection mode.
