Collector pump Q5
When using a solar collector, a circulating pump for the collector circuit is required.
Pump H1 Q15
Pump H1 can be used for an additional consumer. Together with an external request
for heat at input H1, it is possible to operate an air heater or similar.
Boiler pump Q1
The connected pump is used for circulating the boiler water.
Bypass pump Q12
The connected pump serves as a boiler bypass pump for maintaining the boiler return
temperature.
Alarm output K10
The alarm relay signals faults, should they occur.
Switching on takes place with a delay of two minutes.
When the fault is corrected, that is, when the fault status is no longer present, the relay
will be deenergized with no delay.
If the fault cannot immediately be corrected, it is still possible to reset the alarm relay.
This is made on operating page “Faults“.
2nd pump speed
This function facilitates the control of a 2-speed heating circuit pump, allowing the
pump’s capacity to be lowered in reduced mode (e.g. during night setback). In that case,
multifunctional relay QX is used to activate the 2nd pump speed in the following
manner:
1st speed
output Q2/Q6/Q20
2nd speed
Output Q21/Q22/Q23

Time program
For heating circuit P, only time program 3/HCP is available. For more detailed

H2 pump Q18
Pump H2 can be used for an additional consumer. Together with an external demand
for heat at input H2, it is possible to serve an air heater or similar.
System pump Q14
The connected pump can be used as a system pump for supplying heat to other
consumers.
The system pump is put into operation as soon as one of consumers calls for heat. If
there is no demand for heat, the pump will be deactivated followed by overrun.
