All the temperature sensor menus
All the windows associated with the heat pump's temperature sensors are
presented below. Note that you cannot make any settings in these menus,
only read the current values. Some menus are standard for all models of
Greenline HT Plus while others are only available in combination with
different accessories.
The sensors give an alarm if the temperature is outside of the permitted
interval/values.

Return
The menu shows the temperature in the heating system's return, i.e. the water from the
radiators back to the heat pump in heating mode. This temperature varies depending on
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
container in the hot water cylinder. The temperature is approximately 5ºC lower than the
temperature of the hot water inside the inner container.
The menu only applies together with a fl ow sensor. If an extra curve with mixing valve
is used, for example, for a fl 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 only applies 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 temperature of the radiator water as it leaves the heat pump. It
varies depending on the outdoor temperature and whether the heat pump is in hot water
production mode.
The menu shows the temperature of the water that is led into the heat pump. It varies
depending on the outdoor temperature and whether the heat pump is in hot water produc-
tion mode. The heat pump stops at 57ºC for reasons of safety.
The menu shows the temperature of the heat transfer fl uid that is led into the heat pump
from the bore hole or the ground. It can vary between -5ºC to +15ºC during a season.
The menu shows the temperature of the heat transfer fl uid that is led out of the heat
pump to the bore hole or the ground. Normally, during operations, it is 1.5 - 5.0 degrees
lower than the heat transfer fl uid that is led into the heat pump.

Note
All sensors are not included as
standard on the heat pump, some are
available as accessories for different
