HONEYWELL FC-QPP-0001 Module

New original DCS Module FC-QPP-0001 In Stock

Description 

Causes of coil freeze-up include central system circulating pump or boiler failure, outdoor air damper or control valve malfunction, and uneven temperature distribution. A low-limit controller can help prevent coil freeze-up by overriding other control system components to close the outdoor air damper and open the return air damper and coil valve. Effective freeze-up protection depends on available heat in the system and flow through the coils.

Coils can also freeze when low-temperature outdoor air leaks through defective dampers. Frequent inspection of dampers should be made to detect bent and broken damper linkages, warped damper blades, and defective or missing blade seals that can contribute to coil freeze-up.
