Troubleshooting

Before troubleshooting the system, ensure that:

• All mechanical and electrical connections are

secure and tight

• All system wiring is correct

• Fuse is not blown (3A Automotive “ATO” type fuse

for 24VAC)

• That a system ground is properly connected to the

heater. Nuisance shutdowns are often caused by a
poor or erratic ground.

The service display can be accessed by pressing and holding the UP and MENU buttons for 3+ seconds. The

service display does not affect operation of the unit which continues to operate in the background. When in this

mode, pressing the UP or DOWN buttons will toggle through the various information reported. Some items (Fault

History and Sensor Temperatures) have multiple values (press UP or DOWN buttons to scroll through the addi-

tional information). The service display mode may be exited to return to the previous display be pressing the UP

and MENU buttons or it will automatically be exited if no button is pressed within 60 seconds.

The following operational status messages are displayed in Pool, Spa, and Remote operating modes.

Message

Description

Recommended Troubleshooting

Comp Start Delay

Notification that the compressor is under a

5-minute delay before turning On. This can

be bypassed by pressing the UP and

DOWN buttons simultaneously.

Nothing wrong – just notification as to why the unit is not current-

ly operating.

Valve Chng Delay

Notification that the 3-way valves are being

commanded to change positions Pool to

Spa or Spa to Pool.

Nothing wrong – just notification as to why the unit is not current-

ly operating.

WPS Closed

3-way valves not switched because water

pressure switch still closed.

Check settings – pump operation Disabled?

Defrost

Unit is performing a Defrost cycle.

Nothing wrong – just notification as to why the unit is not current-

ly operating.

Heating

Unit is operating and running a heating

cycle.

N/A

Cooling

Unit is operating and running a cooling

cycle.

N/A

External Heat

The AUX Mode setting is set to EXTERNAL

HEAT meaning an external device (solar

heating system) is running 1st stage instead

of the heat pump.

Verify desired settings.

Outside Lockout

The compressor is not running because the

ambient temperature is too cold as meas-

ured by the Ambient sensor.

Verify Outside Lockout temperature setting.

Check Amb Temp sensor value in Installer sub-menu and replace

if value is inconsistent with ambient temperatures.

Disable this function in the Installer/Service sub-menu if Outside

Lockout is not desired.

No Demand

Demand has been satisfied and the unit is

in standby.
