System 12: Setup and Programming

In this multi zone system the FW200 is installed in the boiler for pure outdoor reset without room influence on the heating curve. Zone control is handled by a zone valve panel with room thermostats in each zone. Use of an ECM pump (e.g. Grundfos Alpha) for a zone pump recommended to reduce energy consumption, risk of noisy pipes, and to establish a constant delta T.

Install suitable 3rd party thermostats in each zone in a location that best represents its conditions. Avoid locations exposed to direct or indirect sunlight, heat sources, draft, etc. that can lead to malfunctioning.

DHW is generated by the boiler loading the indirect fired DHW tank following the DHW program. This system can also be realized with a combi boiler eliminating the DHW tank if the capacity is sufficient for the DHW load.

Initial setup:

Program the 3rd party room thermostats according to the manufacturer's instructions. It is recommended to set up a day and night heating program with reduced temperatures at night and when the zone is unoccupied.

Boiler and FW200 programming:

See the installation instructions for description of buttons and displays, and for details on setup and programming.

Power up the boiler.

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 the boiler for permanent day mode by switching the dial on the FW200 to

Comfort

Set the room temperatures for the three specified temperature levels.

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.

Set the remaining parameters as applicable.

Set up the weekly program for DHW generation.

When done, ensure the mode selector is set to AUTO.

The room temperature will be displayed.

Additional information

With outdoor reset the boiler will provide the water temperature according to the heating curve. There is no room influence on the heating curve in this system.

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 unless the 3rd party room thermostat is satisfied prior.

During DHW day mode the boiler will charge the DHW tank when a demand is sensed by the DHW tank tem- perature sensor. When DHW is satisfied, or after one hour, the boiler will return to space heating mode.
