Im doing a job where the outsdie design temperature is -5 deg C. Obviously to protect the AHU cooling coil, the design drawings show a medium temp hot waer preheat coil on the air handling unit and it is sized to bring the air temperature up to +5 deg C. The design document also mention something about a frost thermostat. What is it that should control the valve on the preheat coil.?? A temperature sensor down stream of the coil within the unit? Should the stat actually be a temperature sensor??
