5 Installation
5.1 Installation instructions
• Isolate the appliance from the electrical supply.
• Avoid installing the thermostat close to fridge, radiator, kitchen, computer,
window, doorway or other over-cooling, over-heating and temperature changed
frequently areas. The best position to install the thermostat is a dry place which
can precisely reflect room temperature, and has low interference.
• Ambient temperature: -5 °C~40 °C
• Relative humidity: Max RH 85% (23 °C)
• Altitude: Less than 2000 Meter
5.2 Installation of room thermostat

6Operation instructions
OR30 room thermostat has the advantages of easy operation and practicality. The
function of it is operated by two key and a knob.
•Fault reset: Press “UP” keys to reset if the fault code occurs.
•Check CH/ DHW temperature: Press “Down” key to check the CH/ DHW
temperature, and then press “UP” key to exit.
•Set target room temperature: Increase or decrease the room temperature by
rotating knob.
•Set the target temperature of DHW: Press “DOWN” key twice to check DHW
temperature, then press “DOWN” and “UP” simultaneously to set the target
temperature of DHW. Adjust the target point by “DOWN” and “UP” key. Press
“DOWN” and “UP” once simultaneously to exit.
•Temperature calibration: Press “DOWN” and “UP” simultaneously for 5s to start
temperature calibration. LCD shows battery icon, and calibrates the temperature
by “DOWN” and “UP” key. Press “DOWN” and “UP” simultaneously once to exit.
•Default reset: Press “UP” key for 5s until LOD blinks.Press any key to exit.
• The temperature displayed on thermostat is different from thermograph.The test
methods of thermograph and thermostat are different. In general conditions,
thermostat’s temperature sensor is more precise than thermograph. Due to the
difference of regions and environments thermostat has a slight deviation. If this
deviation is large (>5 °C), you can use “temperature calibration” to adjust (See
part 6.1).
6.1 Temperature calibration
Due to the regions and environments thermostat has a slight deviation. user can
adjust the temperature through “temperature calibration”.
▶ Press up(P8) and down(P9) key together to enter temperature correction and
then the battery icon will flash up on the LCD.
▶ Adjust the value by “up(P8)”and “down (P9)”key. If the temperature difference is
not very obvious, this function is not recommended.
