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

additional 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.

N/A

External Heat

The AUX Mode setting is set to EXTERNAL

HEAT meaning an external device (solar

of the heat pump.

Verify desired settings.

Outside Lockout

The compressor is not running because

the ambient temperature is too cold as

measured 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.
