agreement (NDA). The second one is available at www.roger.pl.

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 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.

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 buffer power supply unit (e.g. PS-15DR,

PS20) 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 dedicated to temperature [°C]

presentation. 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 temperature setting is displayed

all the time.

LED indicators

In the top part of HRT82AC panel there are located six LED indicators. Their functions are explained

in table 3.

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.

Touch buttons

HRT82AC panel is equipped with four touch keys. Their functions are explained in table 4. 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

Front panel and base must be properly oriented in order to ensure functioning of tamper

resistance.

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 at the same time.

If necessary, HRT82AC settings can be modified with RogerVDM software (available at

www.roger.pl) after connection to RUD-1 communication interface.

Fig. 5 HRT82AC and RUD-1 connection

Connection and configuration procedure

1. Connect device to RUD-1 communication interface according to fig. 5

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, communication channel and serial port

with connected RUD-1 –see fig. 5

6. Select Connect button, the software shall establish connection with the device and automatically

switch to configuration window

7. Enter required settings (configuration window is shown in fig. 7, while options are described in

table 6)

8. Select Send to Device button –the software shall upload new settings

9. Remove jumper from MEM pins

10.Restart the device (place and remove jumper on RST pins or switch power supply off and on)

Note:

During connection procedure placing jumper on MEM pins and restarting the device restores its

factory default settings.
