Page 3: Specifications
The HPC is 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. - Page 4 Observe national and local electrical codes. Observe voltage and current limits marked on the module. Do not connect 115 volts to any terminal of the HPC or HPC Plus. They are Class 2 (low voltage) control devices. Do not use the HPC or HPC Plus as a final safety device.
- Page 5 Supplying the HPC or HPC Plus with Power The HPC and HPC Plus are powered by 24-volts AC and rated at 8 VA. To supply the module with power, connect the 24 volts to Terminals 15 and 16 by the label marked “Power Input 8 VA.”...
- Page 6 Connect the Remote Temperature Sensor’s red wire to Terminal 5. Connect the black wire (–) from both sensors to Terminal 4. To wire the other sensors to the HPC or HPC Plus, refer to the installation instructions shipped with the sensors.
- Page 7 Terminals 6 and 7 are for the fan status. On the HPC, Terminals 7 and 8 are for filter status. On the HPC Plus, Terminals 7 and 8 are for the Compressor Stage 1 status. These are dry contact closure, digital inputs and are connected as normally open with the fan status as closing when the fan is on and the compressor status as closing when the compressor is on.
- Page 8 Terminals 13 (F) and 14 (GND) are used for making a connection from a general fault input (refer to the “Wiring the HPC or HPC Plus, Inputs, General Fault Input [HPC Plus Only]” section of these instructions). Terminal 12 (E) is not active.

Page 9: Network Communications
The digital relay outputs tie in directly to the six relay output status LEDs located on the case of the HPC or HPC Plus. The relay output status LEDs match the status of the relay: If the contact is closed, the relay is energized and the LED is on. - Page 10 Addresses are assigned in the software during system formatting. Use the system printout to find the address of the HPC or HPC Plus being installed. Refer to Figure 3 and set the switches with the correct address from 00 to 63. If a Lingo™...

Page 11: Checking Installation
HPC/HPC Plus Installation Instructions Checking Installation Turn on the power to the HPC or HPC Plus. Make sure that power to the heat pump unit and its control circuitry is on. If the executive module is operating properly, the HPC or HPC Plus begins to control the heat pump in about 3 minutes (after performing a self-diagnostic check and establishing communications with the executive module). - Page 12 HPC/HPC Plus Installation Instructions This page intentionally left blank.
