The Hydro Air Fan Control is an interface between the thermostat and air handler. It also has an isolated end switch to start the boiler and/or pump. When the thermostat calls for heat, the Fan Control energizes the end switch relay and allows the fan to operate at low speed when the water is above the optional aquastat setting. When the thermostat calls for cooling, the Fan Control energizes the condenser and operates on high speed. The HAFC201 also includes three built-in fan time delay options, two selectable pump exercise modes, a secondary aquastat connection for freeze protection and the ability to switch a pump and / or boiler.

External Diagnostics The external lights show full functionality of the Hydro Air Fan Control. The green light should always be on indicating that power is connected. Red lights indicate fan operation for heating and cooling modes.
THERMOSTAT C Optional: Common side of transformer to power some styles of thermostats R Red - Side of transformer use to switch all functions W White - Heating signal Y Yellow - Condenser signal G Green - Fan Signal WATER COIL AQUASTAT TT Remove factory installed jumper and connect to aquastat at air handler to control operation of the fan when in the heating mode. FREEZE PROTECTION AQUASTAT TT Connect to aquastat or thermostat to sense low ambient temperature. Reduces the chance of pipes freezing by energizing the pump dry contacts. PUMP DRY CONTACTS XX May switch pump directly by bringing in external line voltage or connect to “TT” on switching relay. BOILER DRY CONTACTS XX Connects to the boiler or “T T” terminals on a switching relay.
AIR HANDLER C Common side of transformer to power the Fan Control R Red - Side of transformer used to switch all functions Y Yellow - Condenser signal One Speed Motor Glow Connect the fan to the relay. Keep the jumper installed between Ghigh and Glow. Two Speed Motor GhighRemove jumper and connect Ghigh to the high speed fan relay and connect Glow to low speed fan relay.
Switch Settings (HAFC201) 1 1 minute on fan delay, in heating mode. 2 3 minute on fan delay, in heating mode. 1&2 4 minute on fan delay, in heating mode. 1&2 3 Pump dry contact activated for 2 minutes every 24 hours (boiler contracts not activated). 4 Pump dry contacts activated for 30 seconds every two weeks (boiler contacts not activated).
