4. Press General.
5. Press Htg/Clg Device Type and select On-Off or Floating. Changing this option reboots the controller in
order to apply the change.
6. Press
Save and the back arrow to return to the previous screen.
When in Floating mode, the Actuator Stroke Time must also be set to match the equipment. To set the actuator
stroke time:
1. Press the Menu icon.
2. Press Setup.
3. Press Equipment Setup.
4. Press General.
5. Press Actuator Stroke Time and adjust accordingly.
6. Press
Save and the back arrow to return to the previous screen.
Configuring the supply fan - fan coil only
Two-pipe or four-pipe fan coil units support three different types of supply fans: 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 Setup.
3. Press Equipment Setup.
4. Press Supply Fan.
5. Press Supply Fan Type and select Single Speed, Multi-Speed, or Variable Speed.
6. Press Save and the back arrow
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 of 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. To adjust these values:
1. Press the Menu icon.
2. Press Setup.
3. Press Equipment Setup.
4. Press Supply Fan.
5. Press Medium Speed On Cmd and adjust accordingly.
6. Press High Speed On Cmd and adjust accordingly.
7. Press
Save and the back arrow 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, when the Start Voltage is above Full Speed Voltage, the VSF output is
set to 10 V or the Start Voltage minus 1 V, whichever value is the lesser, when the fan is turned off.
