Configuring the Supply Fan - Fan Coil Only
On fan coil units (2-pipe or 4-pipe), three different types of supply fans are supported. These are single-speed fans,
multi-speed fans (up to three discrete speeds), and VSF using a 0 to 10 V control signal and an optional binary on/
off command. Note that fan control is not available when in VAV mode. To select the fan type:
1. Press the Menu icon.
2. Press Equipment Setup.
3. Press Supply Fan.
4. Press Supply Fan Type and select Single Speed, Multi-Speed, or Variable Speed.
5. Press to save and
to return to the previous screen.
For multi-speed fan control, you can adjust the point when the medium or high speed turns on. The fan speed is
based on the load on the cooling/heating device, and is a percentage between 0 and 100. By default, the Med
Speed On Cmd is 33% and the High Speed On Cmd is 66%. When only two fan speeds are used, you must set the
High Speed On Cmd to 100% to disable the third speed and set the Med Speed On Cmd to 50%. To adjust these
values:
1. Press the Menu icon.
2. Press Equipment Setup.
3. Press Supply Fan.
4. Press Medium Speed On Cmd and adjust accordingly.
5. Press High Speed On Cmd and adjust accordingly.
6. Press to save and
to return to the previous screen.
