Room operator unit
Room unit to operate individual room control systems in hotel rooms
• Displays room temperature setpoint and setpoint adjustment
• Individual setpoint adjustment with "plus" and "minus" membrane switches
• Individual manual fan-speed selection for fan control (up to 3 speeds) or
selection of "Auto" operating mode
• Measurement of room temperature with a built-in or externally connected
temperature sensor
The HTC3.2 operator unit for control of indoor room conditions is used in conjunction
with the HRC3.1/HRC3.2 room controllers. The room operator unit detects the
temperature and transmits it to the HRC3.1/HCR3.2 room controllers for room
temperature control. The room operator unit displays the operating mode in the hotel
room and can be used to operate the fan coil unit, either manually or automatically via
the connected room controller.

- Page 6 Slave On/Off In a control loop with several room units, the temperature is measured in one device only (the master). The LS flag (SL = 0) determines whether the room unit should measure the temperature, or whether it is a slave device (SL = 1), in which case the temperature sensor is disabled.
- Page 7 Correcting the If the sensor is in an unsuitable location, the measured value can be corrected with a measured value temperature offset. The correction can be undertaken with the SCOPE or HSC (Hotel Solution Commissioning) tool. In the standard application the basic setting for the temperature offset is –4 K. This applies to the room operator unit in cases where the temperature is measured with the internal room sensor.
