Solar pump ext exch K9
Solar pump buffer K8
Solar pump swi pool K18
Instant WH pump Q34
PWM-modulated output controlling the speed of pumps. If no modulating signal is
calculated internally due to the type of function selected, 0% is output for OFF or 100%
for ON.
None
P1 output has no function.
Boiler pump Q1
The connected pump is used for circulating the boiler water.
DHW ctrl elem Q3
Controlling element for the DHW storage tank.
DHW intern circ pump Q33
Charging pump for DHW storage tank with external heat exchanger.
Heat circ pump HC1 Q2
Pump heating circuit HC1 is activated.
Heat circ pump HC2 Q6
Pump heating circuit HC2 is activated.
Heat circ pump HC3 Q20
Pump heating circuit HC3 is activated.
Collector pump Q5
When using a solar collector, a circulating pump for the collector circuit is required.
Solar pump ext exch K9
For the external heat exchanger, Solar pump ext exch K9 must be set at the
multifunctional relay output QX or PWM output P1. If both a DHW and buffer storage
tank are available, External solar exchanger (5841) must also be set.
Solar ctrl elem buffer K8
When using several heat exchangers, the buffer storage tank needs to be set at the
respective relay output and, in addition, the type of solar controlling element must be
defined on Solar controlling element (5840).
Solar pump swi pool K18
When using several heat exchangers, the swimming pool needs to be set at the
respective relay output and, in addition, the type of solar controlling element must be
defined on Solar controlling element (5840).
Instant WH pump Q34
Controlling element for instantaneous water heater.
