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 base-
frame.
•
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.
