5.5 Pump control
Digital inputs and outputs can be configured for pump control.
All the pumps can use run indication with malfunction alarm or an alarm input connected to a motor
protection or similar.
5.5.1 Heating circuit
The circulation pump for the heating circuit will always run when the outdoor temperature is lower
than a settable value (FS +10°C). At higher outdoor temperatures the pump will run when the
heating output is larger than 0V.
If no outdoor temperature sensor has been configured, the stop temperature can be set to 0°C. Then
the pump will only run on heat demand.
The pump has a settable stop delay.
The pump will be exercised once daily at 3 p.m. for one minute or the set shortest running time,
whichever is the longest.
5.5.2 Exchanger circuit, liquid connected exchangers
The circulation pump for the exchanger circuit will run when the output to the exchanger valve is
larger than 0V.
The pump has a settable, shortest running time.
The pump will be exercised once daily at 3 p.m. for 1 minute, or the set stop delay, whichever is the
longest.
5.5.3 Cooling circuit
The circulation pump for the cooling circuit will run when the output to the cooling valve is larger
than 0V.
The pump has a settable, shortest running time.
The pump will be exercised once daily at 3 p.m. for 1 minute, or the set stop delay, whichever is the
longest.
