Refer to
Fig 26 and
This mode selection is for hydronic heating systems with single or multiple water heaters (Maximum 4
water heaters) in primary/secondary piping configuration with or without Outdoor Air Reset (S4).
The system temperature is controlled by the System sensor (S3).
The Water Heater Pump (P1) runs during any call for heat.
The System Pump (P2) (if connected to the MVB) runs whenever the system is enabled for heating and
the outdoor air temperature is lower than the warm weather shut down (WWSD) temperature setting (if
utilized).
The Water Heater Pump (mandatory) and System Pump (optional) are delayed "off" as user defined in
the ADJUST menu.
