Prr Error Condition
The Prr error condition indicates a problem with regulation sensor.
The system is constantly verifying if temperature probe reading is
within normal limits.
Note that water temperature must be over 35
°
F in order to carry out the following steps.
Pressing any key after each step resets system. Power can remain On.
1• Verify if regulation probe (sensor
located in spa) is properly
connected.
3• Reconnect probe.
If Prr error condition still persists,
replace probe with a spare and
place probe head directly in spa
water.
If problem is solved, replace
probe.
4• Replace board if problem persists.
2• Disconnect probe connector
and clean probe connector pins.
Even a small coating of film may
cause a bad connection.
