System 2: Setup and Programming
In this single zone system the FW200 is installed in the
living space in a location that represents the conditions
of the entire zone. Avoid locations exposed to direct or
indirect sunlight, heat sources, draft, etc. that can lead to
over compensation.
DHW is generated directly by the combi-boiler without the
need for a storage tank.
Initial setup:

Additional information
With outdoor reset the boiler will provide the water tem-
perature according to the heating curve adjusted by the
level of room infl uence (if enabled).
The boiler will always attempt to run at its highest

efficiency in low fire for as long as necessary.
 The boiler will shut down when the target temperature
is reached followed by a 3 minute post purge by the
pump.
The boiler and the pump will start again when the

supply water temperature drops 18°F (10°C) below
the set point.
When the demand for hot water is sensed by the flow

sensor, the boiler will change to DHW mode. When the
DHW demand ends, the boiler will return to heating
mode.
