Operation
Operation of the Primary
When a Low Loss Header Panel is connected to a boiler system, the panel regulates the water distribution quantity to
accommodate demand. If the room or floor temperature falls below the user’s designated setting on a thermostat, for
example (sold separately), the panel initiates a signal which has the control start the boiler pump and zone pumps. When
the room temperature is satisfied, the thermostat or aquastat disconnects the heat source and pump.

Operation
Operation of the Domestic Hot Water (DHW)
When there is a Domestic Hot Water application, and an
aquastat demand is signaled, the panel disconnects the
active zone pumps and sends a message to the boiler to
raise the internal boiler water temperature. This water
is heated and distributed as domestic hot water, when
the domestic hot water demand is satisfied; the system
disconnects the high temperature output and reverts to
the preset zone temperatures that were previously active.
This method of providing precedence to the domestic hot
water requirements before the space heating load of a
building is known as domestic hot water priority.
