Troubleshooting Guide
1. Issue: Motor will not automatically turn-down to the reduced speed after
two hours when connected to a single speed timer.
Action: Any command to change speeds after the initial mandatory two-
minute prime cycle will over-ride the automatic turn-down function. Turn the
motor o at the timer / breaker, wait one minute, then turn the power back
on. The software will have reset in this time and should operate as required.
2. Issue: Motor will not automatically turn-down to the reduced speed after
two hours when connected to a single speed timer after changing the default
reduced speed.
Action: It is likely that the default reduced speed change occurred after the
two-minute prime cycle, over-riding the automatic software function. Turn
the motor o at the timer / breaker, wait one minute, then turn the power
back on. The software will have reset in this time and should operate as
required.
3. Issue: Motor will not change speeds when requested by the automation
controller.
Action: Refer to the appropriate section in this guide to conrm the cable
connections to the controller relays have been made correctly. If all three
speeds are wired to the automation controller properly, the likely issue is that
more than one low voltage signal is being received by the motor. Conrm
that only one relay is being activated at a time. As an example, if the motor
is running on HIGH speed, as activated by the relay connected to the HIGH
speedwires[Black(+)andWhite(-)],thatrelaywillneedtobepowereddown

4. Issue: Solar heating system is not working properly.
Action: Assuming this issue was not pre-existing, the programmed low
speed on the imPower likely does not provide sucient ow / pressure to
pump the water up to the solar heating units. Change the speed to medium
and determine if this solves the issue. If it does, change the default reduced
speed to medium per the appropriate procedure outlined in this guide.
