Typical WSHP Lockout Board Without an Accessory Terminal

Important Wiring Notes for Variable Speed Flow Centers:

Heat Pumps Without an Accessory Terminal

Many geothermal heat pumps have an accessory terminal (sometimes labeled “A”or “ACC”). One of the

purposes for the accessory terminal is for control of a solenoid valve for open loop systems. However,

it also aects the operation of the Grundfos UPC-GEO variable speed pump controller. This document

will address wiring for systems without an accessory terminal.

The accessory terminal is typically connected to the output from the lockout board to the compressor

contactor coil (labeled “CC” in the example below). The compressor contactor is only energized after

the anti-short cycle delay, and if there are no lockouts. If the water solenoid is connected between “C”

(common) and the heating/cooling thermostat terminal (”Y” or “Y1”), the solenoid will be energized

any time there is a thermostat call. Most of the time, this approach works ne. However, if the heat

pump is locked out, the water will continue to run even when the compressor is locked out, potentially

causing substantial use of water and electricity for the pump. Therefore, using the“CC” connection to

engage an accessory ensures that the solenoid valve will not open if the unit is locked out.

NOTE: This only applies to solenoid valves without an end switch. Solenoid valves with an end switch

must be wired to the thermostat heating/cooling terminals.

A similar issue could occur with the variable speed pump controller. If the heat pump is locked out, and

the controller is in temperature dierence (∆T) mode, the thermostat will continue to call, but there will

be no ∆T because the compressor is o. Once the heat pump is reset, the controller may not be able to

react qucikly enough, potentially causing insucient water ow. When an accessory terminal is used,

the control will only be enabled when the compressor contactor is energized.

If the heat pump being installed/serviced does not have an accessory terminal, the example diagram

below provides suggestions for simulating an accessory terminal.
