Heat Pump Controller
Novar Controls Corporation’s Heat Pump Controller (HPC) and the Heat Pump Controller Plus (HPC Plus) are dedicated, direct digital control modules that provide precise and integrated control for heat pump applications.
Applied to single-stage (1 H/1 C) heat pumps that energize the reversing valve internally and require a “call for heat” or a “call for cooling” like a conventional thermostat. It features a time delay that allows a loop water pump time to respond to a call for heating or cooling before it actually energizes the heating or cooling outputs.
Energizes the reversing valve and compressors directly—it does not contain a conventional heating or cooling output. Like the HPC, it incorporates a compressor delay to allow time for a loop water pump to turn on before energizing the compressors. The HPC Plus also features a special general fault input to receive contact closure signals from a variety of safety switches. This input can be used to initiate an alarm or shut down the heat pump unit when the signal is received from the switch.
The EP/2 is the second generation Executive Processor for the Logic One® Building Management System. The EP/2 manages network communications, monitors and logs the operations of the local control modules, and provides expandable and complete integrated data control of the building’s equipment. It also has local area network (LAN) capability and offers the option of a built-in 3.5-inch, high-density floppy drive.
