FOR THE USER
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.
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 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 temperature
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/heater. The temperature is approximately 5ºC lower than the tempera-
ture 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 production
mode. The heat pump stops at 54ºC 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 +8ºC 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.
