Description
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.
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. 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.
The HPC Plus 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.
To select the proper unit for an application, examine the inputs and outputs of
these modules carefully.
This document provides procedures for mounting the HPC or HPC Plus,
connecting the power and network communications, wiring the inputs and
outputs, setting the module address, and checking installation.
NOTE! The HPC Plus requires an EP/2, Savvy, or Lingo as the
executive module. The HPC works with any executive module.

Relay Outputs
The digital relay output terminals are located on the far right side of the terminal
strip under the label “Relay Outputs.” Terminals 21–26 (A–F) are the actual
output connections. Use Figure 2 and Table 1 to determine the correct connections.
Digital relay output D (Terminal 24) is not active because of the analog damper
connection.
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.
§If the contact is open, the relay is de-energized and the LED is off.
Terminal 20 is for one side of a 24 source to be regulated (switched) through
Terminals 21–26 (A–F). The relay outputs are isolated from the other
connections to permit the additional power source. The transformer powering the
module can be used if it has enough capacity.
Network
Communications
Use a suitable shielded cable (Novar Controls WIR-1010, Belden 8761, or
equivalent) to make the communication connections between the HPC or HPC
Plus and the module communications terminals of the executive module.
On the HPC or HPC Plus, the connections are Terminals 17, 18, and 19, located
under the label “Module Network 5V Max.” Make certain that the plus (+) and
minus (–) connections are made correctly.
CAUTION! The Shield connection is not a ground like the other
common grounds on the terminal strip. It is dedicated
for communications only. Do not connect any other
grounds to the Shield connection (Terminal 18).

Setting the Module
Address Switches
Every LOGIC ONE module must have a unique address. The address switch is
located in the middle of the terminal strip (Figure 2).
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™
is used as the executive processor, address switches 64–127 duplicate the settings
for 00–63 (address switch 64 is the same as address switch 00, 65 is the same as
01, etc.). Record the setting on the module address label.

Figure 3. HPC/HPC Plus address settings

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).
A schedule status indicator LED is located on the module’s case above the
terminal strip. If the module is communicating properly, this LED should be
flashing according to the scheduled mode.
§When the HPC or HPC Plus is in scheduled off mode, the LED is off and
flashes on briefly when communicating.
§When the module is in scheduled on mode, the LED is on and flashes off
briefly when communicating.
If a timed override switch has been installed and programmed, it can be tested for
proper operation by pressing it during a scheduled off mode. The LED flashes
rapidly until the override period ends.
The six relay output status LEDs indicate the status of each active digital output.
Verify that the LEDs are lit when the corresponding digital output is on.
If any faults or malfunctions still exist, they are picked up by the executive
module and announced by alarm messages.
