More About HVAC Controls

The main purpose of HVAC and refrigeration controls is to maintain system performance and extend the life of the HVAC or refrigeration unit. Applications where HVAC and refrigeration controls are necessary include air conditioners, water heaters, refrigerators, ice makers and freezers.

Common HVAC controls include time delay relays, which help protect air conditioning, refrigeration and heat pump equipment from damage that can occur by rapid short cycling compressors, and fan blower controls, which control circulating fans in air conditioning, heat pump and forced air systems. Other available HVAC controls manufactured by ICM Controls include condensation controls, dryout thermostats, freeze protection modules, motor starters, starting relays, head pressure and motor controls.

Common refrigeration controls include temperature controls, fan controls and pressure controls. Temperature controls provide limit or temperature control in refrigerated areas. Fan controls are used with refrigeration and air conditioning condenser applications for fan motor speed control. Pressure controls include differential pressure controls, which measure the drop in pressure across two different points of an HVAC unit, and pressure cutout controls, which are designed to de-energize the compressor when pressure falls below the differential setpoint. Choose controls from a variety of brands, including Honeywell, Ranco, White Rodgers and Johnson Controls.

Intellidyne high efficiency controls are compatible with refrigeration, packaged/roof top air conditioning, hydronic steam and forced air heating applications. The technology implemented in these controls reduces the amount of electric and fuel consumption used by HVAC units.
