Why is my Lampoassa V 7.0 Heat Pump compressor running constantly?
If your Lampoassa Heat Pump compressor runs constantly, it could be due to a refrigerant shortage. In this case, you should contact a refrigeration supplier or maintenance. Alternatively, the regulator's processor/software might be faulty. Try turning off the control current switch for 10 seconds, then turn it back on. If the issue persists, contact maintenance.
What to do if my Lampoassa V 7.0 Heat Pump regulator display reads 'Enter code'?
If the regulator display of your Lampoassa Heat Pump reads 'Enter code', it means you've likely tried to adjust settings in maintenance mode. These special settings aren't needed for regular use. You can adjust temperature values in normal mode.
Why is there no text visible on my Lampoassa V 7.0 Heat Pump regulator?
If no text is visible on your Lampoassa Heat Pump regulator, it could be due to several reasons. First, ensure the device is getting power by checking that the control current and master switch are on. Second, a fuse may have blown; try replacing it with a 125 mA fuse. Finally, the display might be broken, or the regulator's circuit board could be faulty, in which case you should contact maintenance.
What to do if my Lampoassa Heat Pump compressor doesn't start and shows a divergence alarm?
If your Lampoassa Heat Pump compressor isn't starting and the regulator display shows 'divergence alarm reading 4 compressor operation', the motor's protection switch may have tripped. Try pressing the motor's protection switch. Also, the suction pressure switch on the pressure switch might have tripped, so try setting off that switch as well.
What to do if thermal relays go off immediately on my Lampoassa V 7.0 Heat Pump?
If thermal relays go off immediately when power is switched on for your Lampoassa Heat Pump, it could be due to a short circuit or a missing phase, causing the motor's protection switch to trip. Contact an electrician. Alternatively, the fuses in the building's master switchboard might be faulty. Check their condition and replace them if needed.
