HOTEL AUTOMATION ROOM SYSTEM
Room operating unit HARS-T03
Room unit to operate individual room control systems in additional hotel rooms
•Displays room temperature and setpoint adjustment
•Setpoint adjustment with "up" and "down" pushbuttons
•1
st
fan-speed selection for fan control ("silent mode") or selection of "Auto"
operating mode or selection for shutting off air-condition
•Measurement of room temperature with a built-in temperature sensor
Application
The HARS-T03.xx room operating unit for control of indoor room temperature is used in
conjunction with the HARS-C10 room controller. The room operating unit detects the
temperature and transmits its information to HARS-C10 room controller for room
temperature control. The room operating unit displays the temperature and operating
mode in the hotel room and is used to control 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 from ±0°C to ±10°C, configured in
controller. The step is 1°C. Each temperature increment/decrement is displayed onto
display as set point.
•Enable fan-coil to run in 1
st
speed
•Change from manual to automatic mode ("Auto")
•Switch Fan coil unit on/off
Switching to "Auto" causes the fan speed to be set automatically by the controller
(Speed 1, 2 or 3).
The temperature setpoint valid for the room is displayed on the LED display panel when
changing the setpoint.
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 comes into effect. When the guest returns to the room,
the guest’s personally selected "Auto" or “1
st
speed” mode becomes active and the
"Comfort" room operating mode is restored.
In conjunction with the HOTEL AUTOMATION ROOM SYSTEM SOFTWARE, the room
temperature setpoints preset for a given room are automatically reinstated when the
guest checks out - "room not rented" mode.
Via HARS-SWxx all temperature parameters can be changed.

Engineering notes
The HARS-T03.xx room operating unit is designed for flush wall mounting and fixed in
a base frame. Cover frames for this base unit are available from the installation ranges
of various manufacturers (see "Ordering").
One HARS-T03.xx room operating unit can be connected directly to the HARS-C10
room controller.
The HARS-T03.xx room temperature control algorithm is not in the room operating unit
itself, but in the room controller application program (firmware). To enable the room
controller to communicate with the room operating unit, there is no need to address the
device – it communicates directly with the room controller (plug and play).

Mounting instructions
To measure the temperature with the built-in temperature sensor, the HARS-T03.xx
room operating unit must be installed in a location suitable for room temperature
measurement.
Heat sources result in false temperature measurements. Ensure a minimum distance of
1.5 m from lamps and heaters-radiators and also a distance from Fan coil unit air flow.
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 HOTEL AUTOMATION
ROOM SYSTEM SOFTWARE.
•The HARS-T03.xx room operating unit should be mounted at eye level in the living
area of the hotel room (apprx 1.5m).
•Lamps and other heat sources in the vicinity of the room temperature sensor must
not be allowed to influence 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 can cause too much heat and increase the
measured temperature.
•Conduits must be sealed where they enter wall boxes, so that draughts does not
falsify the temperature.
•To remove the device, it must be unscrewed from the wall together with the base-
frame.
•The RJ45 connector enables simple plugging the cable with adequate RJ45
connector terminated on flat telephone cable (8x0,14mm
2
).
•The device is intended for fixed installation in a dry, enclosed space.
•For installation in a 3-module mounting box.
•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 devices connected to the same room controller attention should be paid to
correctly connect flat telephone cables to room controller.
Flat telephone cable (or UTP) for HARS-T03.xx must not be mixed with flat cable for
HARS-RT.xx. Mixing those cables could cause HARS-T03.xx or room controller to
malfunction or even damage the device(s).
