Set space heating operation
Determine controlling sensor
For space heating systems, the temperature control can be
based on the outlet or the system supply sensor (optional).
The control will automatically switch to the system supply
sensor once it is connected.
Verify space heat circulator operation
The Space Heating Mode controls the boiler pump and the
diverter valve. When the boiler control receives a space
heating call for heat and the boiler is not heating a DHW
(Domestic Hot Water) call, and the set point is not met, it
turns on the boiler pump and places the diverter valve in the
space heating position. After the space heating call for heat
ends, the boiler pump continues to run for a short period of
time. This pump delay is factory set to 30 seconds. After this
pump delay, the pump is turned off and the diverter valve is
placed into the DHW position.

Set domestic hot water (DHW) operation
Verify DHW operation
The DHW Heating Mode controls the boiler pump and the
diverter valve. When the boiler control receives a DHW call
for heat from the DHW flow switch, it turns on the boiler
pump and puts the diverter valve in the DHW position to
route boiler water through the brazed plate heat exchanger.
During the call, the boiler control will modulate to maintain
the DHW outlet temperature to the DHW set point.
After the DHW call for heat ends, the boiler pump continues
to run for a short period of time. This pump delay is factory
set to 30 seconds.
