Commissioning the heat pump
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 of Greenstore 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.
Read the start delay
The function shows the time remaining until the heat pump starts again
after a previous stoppage. The heat pump will not start if there is no
heating or hot water demand.
Setting the electric heater
Electric heat timer
The function gives you the possibility to set the time that should elapse
before the electric heater starts if the heat pump cannot produce
sufficient heat on its own. On delivery the heat pump is set to one hour.
Ramp time open
Here you set the time that is required for the electric heater to go from 0
to 100%. In some cases the ramp time open, may need to be adjusted to
eliminate over exciting the system.
Ramp time close
Here you set the time that is required for the electric heater to go from
100 to 0%.
Show connected electric capacity
Check how much the electric heater (in percent) has been enabled. See
more information under the heading Technical information.
Return to factory settings
Return to the factory settings in menu 12. If on Customer level 1 or 2
when selecting Return to factory settings, only the settings in the
displays accessible from Customer level 1 and 2 will be reset. If on the
Installer/Service level when selecting Return to factory settings only the
displays accessible from Installer / Service level are reset.
All sensors are not included as
standard on the heat pump, some are
available as accessories for different
application areas. See more
information 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 according to the heating mode. The temperature varies with 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 heater. The temperature is approximately 5ºC lower than the temperature of the
hot water inside the inner container.
This menu only applies together with a flow sensor. If an extra curve with mixing valve is used,
for example, for an underfloor heating system, you can see the temperature on the flow 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 fitted.
The menu shows the compressor’s working temperature. The temperature varies between 70ºC
and 125ºC during operations.
The menu shows the flow 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 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 fluid that is fed into the heat pump from
the bore hole or the ground collectors. It can vary between -5ºC to +15ºC during a season.
The menu shows the temperature of the heat transfer fluid that is fed out of the heat pump to
the bore hole or the ground collectors. Normally, during operations, it is 1.5 - 5.0 degrees lower
than the heat transfer fluid that is fed into the heat pump.
