How to troubleshoot a water therm open alarm on a Pentair ULTRATEMP 110?
To troubleshoot a water therm open alarm on your Pentair Heat Pump, which indicates an open water temperature sensor circuit, start by testing the thermistor using the 10k ohm resistance test. If the test shows an open circuit, replace the thermistor. If the thermistor tests good, the issue is likely with the control board, which should be replaced.
What to do if Pentair ULTRATEMP 110 Heat Pump shows LOW WATER FLOW alarm?
If your Pentair Heat Pump displays a LOW WATER FLOW alarm, it means the pressure switch isn't sensing water flow. Here's what you should check: * First, ensure your water circulation pump is running. * Second, check for sufficient water flow by cleaning dirty or worn filters and clogged lint traps. Backwash if needed, or replace the filter element. Inspect and clean the pump impeller. Adjust plumbing valves and repair any suction air leaks. * Third, make sure any external water bypass around the heat pump is closed. * Finally, with water flowing, check the resistance of the water pressure switch; if it's open, replace the switch.
Why is the fan not turning on my Pentair Heat Pump?
If your Pentair Heat Pump has power and the set temperature is above the actual temperature, but the fan isn't turning and there are no alarms, it could be due to a faulty fan relay, capacitor, fan motor, control board failure, or incorrect wiring. Contact a dealer for guidance before attempting to replace any parts. Potential solutions include replacing the fan relay, capacitor, fan motor, or control board.
Why won't my Pentair ULTRATEMP 110 start?
If your Pentair Heat Pump has power, the green light is on, and the set temperature is above the actual temperature, but the unit won't start heating or cooling and there are no alarms, it could be due to the remote feature being enabled without a controlling device connected. Check to see if the Remote feature on the Control Board is enabled and disable it if needed. Another possibility is a control failure, in which case you should contact a dealer or the factory for advice before attempting to replace parts, but replacing the control board may be necessary.
What to do if Pentair Heat Pump displays HIGH WATER TEMP alarm?
If your Pentair Heat Pump is showing a HIGH WATER TEMP alarm (water temperature above 107°F [41.7°C]), the issue might be a bad thermistor or a faulty control board. Verify the water temperature to see if it is correct. If it is not, use the 10k ohm resistance test to verify the thermistor. If the thermistor is bad, replace it. If the thermistor is good, then replace the control board.
Why Pentair Heat Pump shows LOW WATER TEMP alarm?
If your Pentair Heat Pump displays a LOW WATER TEMP alarm (water temperature below 40°F [4.4°C]), a potential cause is a faulty thermistor or a bad control board. To resolve this, first test the water temperature to ensure it's accurate. If the temperature reading is incorrect, use the 10k ohm resistance test to check the thermistor. Replace the thermistor if it's defective; otherwise, replace the control board.
What does remote pool spa alarm mean on Pentair ULTRATEMP 110?
A REMOTE POOL SPA alarm on a Pentair Heat Pump indicates that the remote pool, spa, and common spade terminals on the back of the control board are all energized at the same time. To resolve this, modify the automation control output so that only either the pool and common or spa and common terminals are energized, but not all simultaneously.
What does suction th short alarm mean on Pentair ULTRATEMP 110 Heat Pump?
If your Pentair Heat Pump displays a suction th short alarm, it indicates that the defrost refrigerant temperature sensor circuit is shorted. This is often due to a faulty thermistor or a bad control board. To fix this, use the 10k ohm resistance test to check the thermistor. If the test shows a short, replace the thermistor. If the thermistor is good, the problem is likely the control board, which will need to be replaced.
What to do if Pentair ULTRATEMP 110 shows water therm short alarm?
If your Pentair Heat Pump displays a water therm short alarm, it means the water temperature sensor circuit is shorted. This is often due to a bad thermistor or a bad control board. To resolve this, use the 10k ohm resistance test to verify the thermistor. If the test shows a short, replace the thermistor. If the thermistor is good, then the control board needs to be replaced.
Why is ice forming on my Pentair Heat Pump?
Ice or frost forming on the outer air coil of your Pentair Heat Pump, typically at the bottom, can occur if the discharge air flow is restricted. Ensure the heater is installed with the required placement clearances for air flow and roof clearance, and do not install it indoors. Also, ensure sprinklers do not spray on the heater. Another cause could be that the outside air temperature is too low and the defrost feature is not enabled. Make sure heater is installed with the required placement clearances for air flow and roof clearance, and do not install it indoors. If ice forms, shut off the heater and allow the ice to thaw.
