Product description
Symbol explanation
The room sensor is an accessory for customers who wish to combine the heat pump with a room
sensor.
The room sensor can display the following information in the display window:
Actual room temperature
Desired room temperature
Actual outdoor temperature
Alarm from control center
The following can be controlled using the buttons on the room sensor:
Set the desired room temperature
Activate TOP-UP for extra hot water
Calibrate the room sensor
The room sensor impact on the heat pump
The following parameters in the control unit can affect the room sensor, also see the Installation
instructions:
HEATING
ROOM FACTOR
FACTOR HP
RS HYST.LOW
RS HYST.HIGH.
Using the room sensor the heat pump works to the desired room temperature faster. Integral
calculation can then be limited when the room temperatures remain within the desired values. When
the temperature falls below the value for RS.HYST.LOW the integral calculation is activated. When the
temperature exceeds the value for RS.HYST.HI the integral calculation is reset and the heat pump
stops.
The value of RS.HYST.LOW and RS.HYST.HIGH can be set in the control unit. Note that the parameter
FACTOR HP must be set to ON.
COOLING
ROOM SENSOR
COOL.HYST.RS LOW
COOL.HYST.RS HIGH
The room sensor can also be used as an addition during cooling. This function is activated by setting
the ROOM SENSOR parameter to ON in the COOLING service menu. Two hysteresis settings
(COOL.HYST.RS LOW and COOL.HYST.RS HIGH) can then be stated in the control unit.
