This menu may be used to allow the boiler to maintain the space
heating system water pressure to ensure that a sufficient amount
of water is in the system. When the system pressure falls 4 PSI
below the set value, the boiler opens the makeup water feeding
valve for a maximum of 2 minutes until the system is filled and
water pressure exceeds the set value. After filling the system,
the boiler runs the circulation pump for 15 seconds in the space
heating mode before completing the process. The makeup water
feeding valve operates only when there is no space heating or
DHW demand.
