All menus relating to temperature sensors

All the menus associated with the heat pump temperature sensors are shown

below. Note that the user cannot make any changes to the settings in these

menus, only read the current values. Some menus are standard for all models

while others are only available in combination with different accessories. The

sensors give an alarm if the temperature is outside of the permitted range/

values.

Note

All sensors are not included as

standard on the heat pump, some are

available as accessories for different

application areas. See more informa-

tion under respective menus.

The menu shows the return temperature in the heating system, i.e. the water from the

radiators back to the heat pump. The temperature varies with the outdoor temperature.

The menu shows the outdoor temperature. Some deviation compared to the true tempera-

ture may occur due to thermal radiation from the house to the installed outdoor sensor.

The menu shows the set and present temperature in the lower section of the outer jacket

of the hot water cylinder T4 (GT4). The temperature is approximately 5ºC lower than the

temperature of the domestic hot water inside the inner cylinder.

The menu is only applicable together with a ﬂ ow sensor. If an extra curve with mixing

valve is used, for example, for an underﬂ oor heating system, you can see the temperature

on the ﬂ ow water in the circuit. The temperature varies with the outdoor temperature.

The menu is only applicable together with a room sensor. The menu shows the set point

value and present temperature in the room where the sensor is ﬁ tted.

The menu shows the compressor’s working temperature. The temperature varies

between 70ºC and 125ºC during operations.

The menu shows the ﬂ ow temperature of the central heating water as it leaves the heat

pump. It varies depending on the outdoor temperature and whether the heat pump is in

domestic hot water (DHW) heating mode.

The menu shows the temperature of the return water that is fed into the heat pump. It

varies depending on the outdoor temperature and whether the heat pump is in domestic

hot water (DHW) heating mode. The heat pump stops at 57ºC for safety reasons.

The menu shows the temperature of the heat transfer ﬂ uid that is fed into the heat pump

from the collector system. It can vary between -5ºC to +15ºC during the year.

The menu shows the temperature of the heat transfer ﬂ uid that is fed out of the heat

pump to the collector system. Normal operations should result in this being 1.5 - 5.0

degrees lower than the heat transfer ﬂ uid that is fed into the heat pump.
