The R85A-001 is an electronic fan control board that provides control of a three-speed line voltage fan motor. It can be connected to a thermostat that by itself does not have the current or voltage rating to switch a fan motor directly. The fan speed input signals can be 24, 120 or 240VAC.
-Fan speed input voltage can be 24, 120 or 240VAC.
- Supplied voltage can be selected to either 24VAC or line voltage by two removable jumpers.
- If line voltage (120 or 240VAC) is supplied to the fan speed voltage select inputs it should be the same voltage as provided to the motor.
