    HEATING- QUICK START & STOP Note to Dealer/Installer: This, and the “Owner Level Programming” sections were originally writ- ten for use by the home owner/operator. As such, much of the language will be owner-directed. The intent of this section is to provide rapid access to very basic operational information. Indi- viduals who will be routinely using, installing, maintaining, and servicing the heat pump, are strongly encouraged to read this entire manual.

  • Page 19: Mode Jumper And Positioning

    Microprocessor Mode Jumper Positioning Mode Jumper Explained The HP7R microprocessor is designed to operate as a Heat-Only or a Heating & Cooling controller. The selection between the two choices is made through the positioning of a mode jumper contained on the microprocessor board. The position of the jumper is set at the factory, and is dependant upon the design of the heater being controlled.

    Controls Configuration & Adjustments... Defrost Systems- Described DEFROST CYCLE (HEAT ONLY UNITS): The microprocessor controller monitors the heater’s air-coil temperature, minimizing air-coil freeze- up during cooler weather conditions. If the controller senses air-coil temperatures conductive to mak- ing ice, the heater’s compressor operation is interrupted while the fan is allowed to continue in opera- tion.
