2. Press Equipment Setup.
3. Press General.
4. Press Unit Type and select 2-pipe, 4-pipe, or VAV.
5. Press to save and
to return to the previous screen.
Note: Selecting VAV reboots the controller in order to apply the change.
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. 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.
For VSF control, the output is configurable for any range between 0 V and 10 V. The parameters are Start Voltage,
Full Speed Voltage, and Minimum Command. Start Voltage is the voltage output at which the fan begins running,
and Full Speed Voltage is the voltage output at which the fan reaches full speed. Minimum Command is the
percentage of the range between the Start Voltage and the Full Speed Voltage. The fan does not go below the
minimum command when the fan is turned on. By default, the Start Voltage is 2 V, the Full Speed Voltage is 10 V,
and the Minimum Command is 20%.
When the variable speed fan is off, the FAN binary output is off and the voltage at the VSF output is 0 V. When the
fan turns on, the FAN binary output turns on and the voltage at the VSF output begins controlling the fan. When the
VSF is configured for reverse acting mode (Start Voltage is above Full Speed Voltage), the VSF output goes to the
lesser of 10 V and 1 V above the Start Voltage when the fan is turned off.
To configure the variable speed parameters:
1. Press the Menu icon.
2. Press Equipment Setup.
3. Press Supply Fan.
