Taco's HAFC201-4 Hydro Air Fan Control is the perfect addition to any hydronic system with an air handler. It acts as an interface between your fan coil and thermostat, and it also has the capability to operate a pump and boiler. The Hydro Air Fan Control uses automatic multi-speed switching to provide the ideal air flow for every application. During heating demands, the fan runs on low and may be set to observe a user-selectable delay. When cooling is called for, the HAFC201-4 energizes your condenser and uses a higher fan speed. Incorporating a Hydro Air Fan Control into your system is quick and easy thanks to Taco's contractor-friendly PC board design. Improving the comfort of your space and the efficiency of your hydronic forced air system is as simple as adding a Hydro Air Fan Control from Taco.
The HAFC201-4 provides several methods to protect your system. Two pump exercising functions ensure that your system is free of sediment, and that your equipment is functioning properly. In low temperature environments, it may also occasionally run your circulator to prevent the liquid in your pipes from freezing.
