4.5 Heating settings
Heating
The
Heating buffer sensor
setting determines the heat source used by heating circuits: either the heat
pump's condenser or a buffer tank. Select other circuit equipment from each circuit’s settings.
Not connected
The heat pump is connected directly to the building’s heating system without a
buffer tank. No buffer tank sensor is connected. There can be an (unpowered)
instantaneous water cylinder, but not a buffer tank regulated by the heat pump.
Heating buffer
sensor
Connected
The heat pump is connected to a buffer tank which is regulated by the heat pump.
The tank is equipped with a temperature sensor which is connected to the heat
pump. Any heating circuits in the system are connected to the buffer tank.
Buffer
Buffer tank temperature.
Design outdoor
temperature
This temperature is used for selecting the necessary heating capacity for the heating
system. At this outdoor temperature point, flow temperature is at its highest. The
Max flow temperature
(selected for each heating circuit) and the
Design outdoor
temperature
are used to calculate the circuit’s heating curve. See section
Design
outdoor temperature
.
4.6 Heating circuits
Heating circuit 1
No
The circuit is not in use.
Direct connection
The heat pump is connected directly to the building’s heating system. The system
has no circulation pump or control valve that would be controlled by the heat pump.
Direct connection, with pump
The system has a circulation pump which is controlled by the heat pump.
Circuit in use
3-way valve
The system has a circulation pump and a 3-way control valve, both of which are
controlled by the heat pump.
Min. flow
temperature
The system will keep the flow temperature determined by the heating curve above
this temperature value.
●
Typical setting: +20...+25 °C
● Set the the minimum flow temperature slightly above the required room
temperature.
Max. flow
temperature
The maximum flow temperature when the outdoor temperature matches the
Design outdoor temperature
setting. The system will keep the flow temperature
determined by the heating curve below this temperature value.
●
Typical setting, floor heating:
concrete 35 °C, wooden 45 °C
● Check the temperature value from the floor or floor heating supplier (or from the
applicable plans and specifications).
Preset heating
curve
Start by setting the minimum and maximum temperature. The flow temperature can
be adjusted using a six-point heating curve. This menu allows you to adjust each
point separately.
Curve values should be tuned in during the first few heating seasons.
