What to do if my evoheat Evo270 shows a water flow failure?
If your evoheat Heat Pump displays a water flow failure, it's likely due to insufficient water or debris in the water system. Ensure there is enough water and inspect the flow volume pump for any failures.
Why does my evoheat Evo270 have high pressure protection?
If your evoheat Heat Pump is experiencing high pressure protection, it's because the exhaust pressure is too high, triggering the high-pressure switch. You should check the high-pressure switch and the cooling return circuit.
What causes low pressure protection in my evoheat Evo270 Heat Pump?
If the evoheat Heat Pump shows low pressure protection, it means the suction pressure is low, which activates the low-pressure switch. Check the low-pressure switch and the cooling return circuit.
What to do if my evoheat Heat Pump has electric-heater overheat protection?
Electric-heater overheat protection in your evoheat Heat Pump is caused by insufficient water flow and a small pressure difference in the water system. You should check if the flow volume system is jammed.
Why is the anti-freeze protection activated on my evoheat Evo270 Heat Pump?
Anti-freeze protection in your evoheat Heat Pump occurs when there is not enough water flow, leading to a small pressure difference in the water system. Inspect the flow volume system for any blockages.
What does refrigerant absorb temp. failure mean on my evoheat Evo270 Heat Pump?
If your evoheat Heat Pump shows a refrigerant absorb temperature failure, the evaporator temperature sensor is likely open or short-circuited. Check or replace the evaporator temperature sensor.
How to fix coil temp failure on evoheat Evo270?
If your evoheat Heat Pump displays a coil temperature failure, it means the pipe temperature sensor is open or short circuit. You should check or change the pipe temperature sensor.
What does anti-freeze temp failure mean for evoheat Evo270?
If your evoheat Heat Pump is showing an anti-freeze temperature failure, the anti-freeze temperature sensor is either open or short circuit. Examine or replace the anti-freeze temperature sensor.
How do I troubleshoot a top tank water temp failure on my evoheat Evo270?
If your evoheat Heat Pump is showing a top tank water temperature failure, it indicates that the water top tank temperature sensor is open or short circuit. Check or replace the water top tank temperature sensor.
How do I troubleshoot a bottom water temp failure on my evoheat Heat Pump?
If your evoheat Heat Pump is showing a bottom water temperature failure, it indicates that the water bottom temperature sensor is open or short circuit. Check or replace the water bottom temperature sensor.
