Boiler Pump run pump for:
Activates the boiler pump output according to selected function.
Any Demand:
Pump Runs during any call for heat.
Central heat, off DHW demand:
Pump Runs during central heat and frost protection call for heat. Pump does
not start for a DHW call for heat and will be forced off if there is a DHW call
for heat and Domestic Hot Water Priority is active.

Domestic Pump run pump for:
Activates the Domestic pump output according to selected function
Never:
Pump is disabled and not shown on status screen.
Primary Loop Piped IWH:
Pump Runs during domestic hot water call for heat. Domestic Hot Water Priority
enable/disable does not affect pump operation.
Boiler Piped IWH:
Pump Runs during domestic hot water call for heat.
Pump is forced off during a central heat call for heat when Domestic Hot Water
Priority “disabled” is selected and when Domestic Hot Water Priority “enable” has
been selected and the DWH call for heat has remained on for longer than 1 hour
(priority protection time).

Explanation:
This piping arrangement does not allow both the Slave 1’s boiler and domestic hot water pump to run at the same time. When call for
Domestic Hot Water is received the DHW pump is turned on and the boiler pump is turned off. However, the system pumps may run to
satisfy a central heat demand that is being satisfied by a different slave. The central heat demand is ignored by Slave 1 until the domestic hot
water demand is ended. If domestic hot water priority is enabled and priority protection time is exceeded the domestic hot water pump turns
off to allow the boiler pump to run.
