Abstract
An air handling system is provided and includes a coil in fluid communication with a water supply piping system and a water return piping system, a water supply piping system for returning the water from the coil to the water supply piping system, a circulating pump, and a control valve disposed in the water return piping system. The control valve controller can cause the control valve to open to a first predetermined position that is less than a fully opened position and modulate in response to a first temperature sensor sensing a temperature below a value such that the pressure drop in the coil and flow to the coil increases at sufficient values to protect against freezing of the water in the coil while also staying within a sufficient range to maintain authority of the control valve when the air handling system is either operating or not operating.
