System 4: 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 type to Baseboard.
—Set the minimum outdoor temperature, building storage capacity, design day temperature, and maximum supply temperature.
—Set the room influence followed by the remaining parameters as applicable.
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 system 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 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 influence (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.
