Maintenance & Troubleshooting

Troubleshooting

This section provides useful information for diagnosing and correcting certain problems which may
occur. Before starting the troubleshooting procedure, carry out a thorough visual inspection of the
unit and look for obvious defects such as loose connections or defective wiring.
Before contacting your local dealer, read this chapter carefully. It could save you time and money.
WARNING
The hints below are for guidance only. If you cannot solve the problem, consult your installer/local
dealer.
The Heat pump will not run.
Please check:
• There is a supply voltage (tripped fuse, power failure).
• The switch on the wired controller is switched on, and whether the correct set point tempera-
ture has been set.
The set temperature level cannot be reached.
Please check whether:
• The permissible operating conditions for the heat pump have been adhered to (air tempera-
tures too high or too low).
• The air inlet or outlet area is blocked, restricted or very dirty.
• There are closed valves or stop-cocks in the water pipes.
The timer works but the programmed actions are executed at the wrong time (e.g. 1 hour too late
or too early).
Please check whether:
• The clock and the day of the week are set correctly, adjust if necessary.
If you cannot correct the fault yourself, please contact Pentair for after-sales service.
