Room operator unit
HTC3.2/..
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
Application
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.

The guest can use the room unit to do the following:
• Adjust the preset room temperature setpoint by ±2 K or by ±4 K in eight steps. The
step size of 0.5 or 1.0 K can be configured in the room controller. The eight
temperature-change increments are indicated by a horizontal scale across the center
of the LCD display panel.
• Enable fan speeds 1, 2 and 3 manually
• Change from manual to automatic mode ("Auto")
Switching to "Auto" causes the fan speed to be set automatically by the controller
(Speed 1, 2 or 3). The fan status is indicated by symbols across the bottom of the LCD
display panel.
The temperature setpoint valid for the room is displayed in digits on the LCD display
panel. Throughout the period for which the guest is checked in, the individual setpointsetting remains valid. It cannot be overwritten by the hotel service staff.
When the guest leaves the room (removing the access card from the card holder) the
system switches automatically to "Auto", and the "Precomfort" room operating mode
with the energy-saving function (widening of the deadband) comes into effect. When
the guest returns to the room, the "Auto" mode remains active and the "Comfort" room
operating mode, with the guest's personally selected setpoint adjustment, is restored.
In conjunction with the HOTEL SOLUTION system, the room temperature setpoints
preset for a given room are automatically re-instated when the guest checks out.

Engineering notes
Base frame The room unit is designed for flush wall mounting in conjunction with base-frames and
cover plates from various manufacturers:
• Bticino Living for HTC3.2/BB
• Bticino Light for HTC3.2/BW
• Vimar Idea for HTC3.2/VB
• Vimar Plana or Ikon for HTC3.2/VW
Up to 4 room units may be connected to one room controller.
STOP
Important note
The maximum permitted current associated with the supply voltage from the
HRC3.1/HRC3.2 room controller must not be exceeded.
(For further information, see data sheet CM2N6313 and CM2N6314.)
Addressing
The room temperature control algorithm is not in the room unit itself, but in the
controller application. To enable the room controller to communicate with the room unit,
the latter must be assigned with an address.
The addresses of the room operator units are set by DIP switch on the back of the
room comfort operator unit.
First room operating unit ADR0=0, ADR1 = 0
Second room operating unit ADR0=1, ADR1 = 0
Third room operating unit ADR0=0, ADR1 = 1
Fourth room operating unit ADR0=1, ADR1 = 1
Configuration menu The room operator unit includes a configuration menu for setting certain parameters.
After a restart, the configuration menu can be displayed as follows:
1. Hold down
2. Press and hold
3. Release
4. Release
STOP
Important note
The configuration menu can only be displayed provided that no other buttons are
pressed when the room operator unit is restarted.
The configuration menu is identified as shown below.

6320Z04
For room temperature measurement, the internal or external room sensor can be
selected. The default is temperature measurement via the internal temperature sensor.

6320Z05
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.
The default setting is SL = 0, i.e. temperature measurement active.
Further control loops can also be defined by means of a special application in the room
controller. In such cases, other room units can measure the temperature on the same
room bus.
Note
+
6320Z06
Offset correction
The error in an NTC 10 kΩ room sensor error combined with a measurement error
results in an error in the measured temperature reading. This can be corrected by
setting an offset correction value.
+
6320Z07
Measured temperature
This menu displays the current measured temperature including the previously set
offset correction value.

6320Z08
LCD display contrast
The LCD display contrast can be adjusted in this menu to suit different lighting
conditions.
Mounting instructions
To measure the temperature with the built-in temperature sensor, the HTC3.2/.. room
operator unit must be installed in a location suitable for room temperature
measurement.
Mounting location
This restriction does not apply if the temperature is measured with an external
temperature sensor. A suitable temperature sensor for this unit is the HSE1.1 cable
temperature sensor. If the VIMAR idea installation system is used, the room
temperature sensor HSE1.2 is also suitable.
STOP
Important note
Heat sources result in false temperature measurements. Ensure a minimum distance of
1.5 m from lamps.
6/10
Building Technologies HTC3.2/.. - Room operator unit CM2N6320en

Page 7
If the sensor is in an unsuitable location, the measured value can be corrected with a
temperature offset. The correction can be undertaken with the SCOPE or HSC (Hotel
Solution Commissioning) tool.
Correcting the
measured value
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.
If a type HSE1.2 external sensor is used for temperature measurement, a temperature
offset of – 1K must be set.
• The HTC3.2/.. room operator unit should be mounted at eye level in the living area
of the hotel room.
• Lamps and other heat sources in the vicinity of the room temperature sensor must
not be allowed to distort the measured temperature. The room unit with the built-in
temperature sensor is not suitable for mounting within reach of the bed, for example,
because items such as bedside lamps cause too great an increase in the measured
temperature.
• Conduits must be sealed where they enter wall boxes, so that the temperature is not
falsified by draughts.
• To remove the device, it must be unscrewed from the wall together with the baseframe.
• The screw terminals of the room operating unit can accommodate only one wire, with
a maximum diameter of 1 mm. When connecting the bus, therefore, we recommend
that the room unit should be connected as the last room-bus device.
• The device is intended for fixed installation in a dry, enclosed space.
• For installation in a 3-module mounting box, depth 50 mm
• Must be mounted horizontally only, with the front plate vertical
• Do not install AC 230 V devices in the same mounting box
• Commissioning must be carried out by trained personnel only
• Do not open the unit
• Local safety and installation regulations must be observed
Commissioning
To operate several devices connected to the same room controller, an address must be
set for each one (refer to "Engineering notes"). Only one device operates with the
factory-set defaults.
In the standard application with only one room unit, the defaults are ADR0=0, ADR1=0
and IE=1(internal sensor active). These are the factory-set values for the room operator
unit.
Note
Measured value corrections are carried out via the configuration menu or the SCOPE
or HSC tool, depending on where the sensors are located.
