General Information
Adjustment
The adjustment means that the temperature level can
be raised or lowered at a specific outdoor temperature.
After this default setting, fine adjustment takes place in
the “Room temperature” menu.
Room temp. reduced -2 (0 to -40)
“Room temp. reduced” is displayed if a room sensor is
installed.
You define here how many degrees the room
temperature will be reduced by during the various
scheduled reduction periods, e.g. Night reduction,
Holiday, etc.
Prim reduced -3 (0 to -40)
If there is no room sensor installed, “Prim reduced” is
displayed instead.
Exact primary flow No
Exact primary flow means that the heat pump never
switches over and heats the upper tank (hot water
charging). This is provided solely by the electric heater.
In summer mode however, i.e. if the outdoor
temperature is above the limit (Heating off, outside), the
heat pump will be allowed to send water to the upper
tank.
Example:
Room temp red -2 means that the room temperature is
reduced by 2 °C from its normal temperature.
Example:
As a general rule, a Prim reduced value of 3-4 °C is
equivalent to a 1 °C reduction in room temperature in a
normal system.
8.7.2 Heat pump
Compressor
Options: Permitted or Blocked.
The product is supplied with a blocked compressor.
When the compressor is blocked, the product operates
like an electric boiler. All other functions are intact.
Permitted means that the compressor is allowed to
operate.
Min. outdoor temp. °C -15 (-22 to 0)
This menu is displayed only if the heat pump is an
EcoAir model, and includes settings for the outdoor
temperature at which the compressor is no longer
permitted to operate. The heat pump starts 2°C above
the set value. The lowest outdoor temperature required
for start is -18°C.
Brine pump on 10 days
Options 0 or 10 days.
After installation is complete, you can choose to run the
brine pump constantly for 10 days to remove air from
the system.
