System 9: 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.
Initial setup:
See the installation instructions for description of buttons
and displays, and for details on setup and programming.
 Power up the boiler.
 Use the FW200 for programming the heating system.
 When commissioning for the first time set the display
language, date and time.

Upon first commissioning the automatic system
configuration starts. Wait 60 seconds and follow the
instructions displayed. You have the option of using
the factory settings or entering custom parameters to
better match the individual requirements.

Set up the weekly heating program for the three
available temperature levels:
— Comfort
— Economy
— Frost (Frost protection)

Take advantage of using one of the preset programs
from the list or enter a custom program.
— Program A
— Program F
— AM weekday worker
— PM weekday worker
— All day
— All day, lunch
— Family
— All day, early shift
— All day, late shift
— Seniors
 Set the room temperatures for the three specified
temperature levels.
 Set up the weekly program for DHW tank loading and
the DHW recirculation pump (if installed). Separate
individual programs can be set up or the hours of op-
eration can be linked to the heating program.

Enter the installer menu to configure the heating zone.
— Set heating circuit to the type of heat
distribution used.
— Set the minimum outdoor temperature, building
storage capacity, design day temperature, and
maximum supply temperature.

Proceed in the installer menu to configure the solar
thermal system. (The solar system requires manual
configuration).
— Run solar system: Yes
— Solar system parameters: Standard system.
— Set options A2 to E as required.
— It is recommended to keep the factory default
solar sys parameters.

Exit the installer menu.

When done, ensure the mode selector is set to AUTO.
 The room temperature will be displayed.
Additional information
The solar thermal system will start harvesting energy
once the collector temperature is at least 16°F (9°C)
warmer than the bottom of the solar tank. The upper
half of the solar tank ("comfort zone") is maintained at
temperature by the boiler during DHW day mode as set in
the DHW programming. The lower half is available for solar
harvesting.
With outdoor reset the boiler will provide the water
temperature according to the heating curve adjusted by
the level of room in fl uence (if enabled).

The boiler will always attempt to run at its highest
ef fi ciency in low fi re 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 fl ow
sensor, the boiler will change to DHW mode. When the
DHW demand ends, the boiler will return to heating
mode.
