Temperature sensor overview
↳
TExt room temperature (°C) Description: Indicates the room temperature measured by an
external room sensor (only if connected).
↳
Temperature sensor status Description: Indicates whether sensor is in working order (OK /
Error / Absent).
↳
Offset (°C) Description: It is possible to adjust the sensor if it shows the wrong
temperature.
↳
T1 outdoor temperature (°C) Description: Shows current outdoor temperature, unless an
external pre-heating element has been installed.
↳
T2 supply air temperature (°C) Description: Shows current supply air temperature, unless an
after-heating element has been installed.
↳
T3 extract air temperature (°C) Description: Shows current room temperature measured by the
extract air.
↳
T4 discharge air after heat exchanger
(°C)
Description: Shows current temperature after counterflow heat
exchanger and before the heat pump.
↳
T5 condenser temperature (°C) Description: Shows current condenser temperature (heating).
↳
T6 evaporator temperature (°C) Description: Shows current evaporator temperature (heating).
↳
T7 supply air after-heating element
(°C)
Description: Shows current supply air temperature after
installation of after-heating element.
Shown only if an after-heating element is installed.
↳ T8 outdoor air temperature before
preheating element (°C)
Description: If an external pre-heating element is installed, the
temperature sensor must be placed before this so that
the unit can be controlled by the outdoor
temperatures.
Only shown if a T8 temperature sensor is installed.
↳
T9 temperature in the after-heating
element (°C)
Description: Shows current temperature in the water after-heating
element.
Used for frost protection of water after-heating
element. When the temperature in the water after-
heating element falls to between 10°C and 5°C, a
0-10V signal is sent to the mixing valve, which allows
hot water to enter and attempts to maintain min. 10°C.
If the temperature in the water after-heating element
falls below 2°C, the unit stops and displays an alarm:
Frost in heating element.
