2. DESCRIPTION AND SPECIFICATION
HRT82AC air conditioning control panel is peripheral device used in a hotel system based on HRC
series controllers. The device communicates with controller using RACS CLK/DTA bus and enables
to adjust air conditioner speed, to start heating or cooling and to read and display room
temperature. Interchangeably, room temperature can also be read by means of such devices with
built-in temperature sensors as HRT82TS temperature sensor module and HRT82MF-CH card
holder.
HRT82AC front panel includes monochromatic display, six LED indicators and four touch buttons
which can be used for switching panel on/off, adjusting AC speed and setting desired room
temperature. The device is equipped with front panel backlight and buzzer.
The panel is offered in two versions: HRT82AC for surface mounting and HRT82AC-F for flush
mounting.

3.2 Power supply
HRT82AC requires 12VDC nominal power supply. The power must be connected to 12V and GND
terminals. Additionally, the GND terminal is used as reference potential for the RACS CLK/DTA bus.
HRT82AC power supply can be provided by connection to 12VDC buffer power supply unit or
connection to AUX output of HRC402DR controller (see fig. 2). Backup battery connected to power
supply unit or directly to HRC402DR controller can be used in order to ensure operation in case of
230VAC power failure.
Note: All devices connected to the same RACS CLK/DTA bus must be connected to common
reference potential (GND).
3.3 RACS CLK/DTA communication bus
RACS CLK/DTA is the addressable bidirectional communication standard developed and applied in
Roger controllers in order to enable their communication with peripheral devices. Addresses of all
devices connected to CLK and DTA lines must be properly configured in range of 00..15. Standard
unshielded signal cables (e.g. U/UTP cat. 5) with maximal length of 150m can be used for RACS
CLK/DTA communication.
3.4 Front panel
OLED display
HRT82AC panel is equipped with monochromatic OLED display to present temperature [°C] and five
icons which signal controller’s state. Depending on HRC controller settings, the panel can display
temperature in two modes. In the first one, the panel based on built-in temperature sensor displays
actual room temperature and after pressing one of temperature adjustment buttons (TEMP+ or
TEMP-) it switches to display temperature setting (blinking value). After a few seconds of inactivity
it switches back to display actual room temperature. In the second mode only configured
temperature is displayed all the time.

Note: In case of firmware 1.1.2.39 or newer, LED indicators can be dimmed after 5s of device
idleness and the display can be automatically switched off after 30 s of device idleness.
LED indicators
In the top part of HRT82AC panel there are located six LED indicators. Their functions are explained
in table 4.

The panel enables to control air conditioner fan speed by means of HRC controller outputs or
connected XM-6DR outputs. Speed is switched with SPSW button. In case of automatic operation,
the HRC controller automatically selects speed depending on difference of actual room temperature
and temperature setting. HEAT and COOL indicators are activated respectively when heating and
cooling is started by HRC controller. Both heating and cooling result from difference of actual
temperature and temperature setting. HRC controller can operate with two pipe and four pipe
systems.
Note: In case of firmware 1.1.2.39 or newer, LED indicators can be automatically dimmed when
panel is idle for 5s.
Touch buttons
HRT82AC panel is equipped with four touch keys. Their functions are explained in table 5. By
default when button is pressed, short acoustic signal is generated by panel.

3.5 Wall mounting and installation guidelines
HRT82AC consists of front panel and base which are factory assembled and require manual
disassembly prior to installation according to fig. 4.
Installation guidelines
•Install device on wall far from sources of heat and moisture
•It is recommended to install device on Ø60mm flush mounting box
•In case of HRT82AC-F base it is necessary to make cut in the wall below temperature detector
(hole in fig. 5) and under glass panel and additionally install the panel in a distance of 1-2mm
from wall to ensure air circulation at the detector
•Front panel and base must be properly oriented in order to ensure functioning of tamper lever.
•All electric connections must be made with power supply switched off
•Run connection wires through hole in device base and then connect wires to screw terminals
•If device and controller are supplied from different power supply units then it is necessary
connect GND terminals of both devices
•Front panel can be regularly cleaned with wet cloth and mild detergent. Do not clean by means
of abrasive materials and strong cleaners like alcohols, solvents, etc.
•Damages resulting from improper maintenance or use are not covered by warranty

4. CONFIGURATION
4.1 Device programming
The address of factory new HRT82AC is ID=7 and such device is ready to communicate with HRC
series controller requiring no additional configuration. The same address is used by HRT82TS
temperature sensor module. Therefore particular controller can operate with only one of mentioned
devices using ID=7 address. In case of HRC controllers with firmware 1.3.12.108 (or newer), two
HRT82AC can be connected in order to control two individual air conditioning zones. In such a case
the second HRT82AC is configured with ID=4 address.
If necessary, HRT82AC settings can be modified with RogerVDM software (available at
www.roger.pl) after connection to RUD-1 communication interface.
Fig. 6 HRT82AC and RUD-1 connection
Connection and configuration procedure
1. Connect device to RUD-1 communication interface according to fig. 6
2. Place jumper on MEM pins
3. Restart the device (place and remove jumper on RST pins or switch power supply off and on)
4. Install and start RogerVDM software
5. In the opened window select device, firmware version, RS232 communication channel and
serial port with connected RUD-1.
6. Select Connect button, the software shall establish connection with the device and automatically
