If the refrigerant flows in a different direction, it causes a switch in the function of the indoor and outdoor coils, and it changes whether heat leaves or enters your home. Adjust Plumbing valves. The heat pump will not operate until incoming water temperature drops to 100 F or lower. 2. 2. I notice that the coils were beginning to freeze/frost over as well. HIGH REFRIG Alarm:Refrigerant high pressure switch is open. Inspect & clean pump impeller. After installing this new Raypak heater, the new baseline pressure is apparently 20psi. If so, then the proving signal is not getting back to the PC Board. No Alarms. Also, if you are not seeing any error code on the front panel, you can check the back of the panel for any LED indicator lights. Check resistance of switch with a full charge, if open, replace switch. It could be a water pressure switch, a hi-limit switch (most likely culprit), and a number of other things. The heat pump will not operate until the incoming water temperature drops to 100 F (38 C) or lower. It keeps triggering the high-pressure cut-off on the outdoor unit. No Airflow Step 3. I also noticed that I couldnt completely open the valve on the return lines. At the air handler, check for 240VAC to the motor. However, it isnt ALWAYS the case. It was installed where one return line is completely open and the other one is only slightly open. The refrigerant systems low-pressure switch is showing as open. In particular, look for kink or rodent damages. 1. Is the heater flashing any error codes or making any off noises? Transformer should output between 24 and 28 volts. Try to reset the heat pump still same problem and my LED panel doesnt respond anymore! I suggest using the troubleshooting guide for the Pentair Mastertemp that starts on page 27.

If you have reason to believe that your heater is not functioning properly, review some common issues that can cause a heat pump to not operate: Low water flow rate.This is the number one issue for the heat pump not working. When the head pressure builds too high, the high pressure switch will open causing the heat pump to shut off immediately. The last time I tried to run it, wont fire up. Some leak detectors, including the INFICON Stratus, measure concentrations in PPM (parts per million). Note: when the opened the manifold last winter to replace the bypass, the manifold and the heat coils have no signs of scales. Then reactivate heat pump's power at disconnect. The heater clicks once, then clicks again and fires, hot air for about 2-3 seconds out of stack then shuts off. Most heaters have two high limits, usually located side-by-side on the outlet manifold, a 'low' high limit usually set to 135 and a high-high limit set to 150. My HVAC technician charged the unit to the required pressure levels. Fault Condition: LOW WATER TEMP Alarm: Watertemperature below 40F.

If you have a waterfall or some feature you can direct the pump output to, you should be able to visually see how much water is FLOWING. Unit is plumbed backwards. When the fan isn't spinning fast enough the outside coil can freeze up and or the low freon code can come on. The 2nd is after modified the 3-port valve to the return lines. Bad refrigerant low pressure switch. Poor water flow can sometimes trigger a High Pressure message, this means that the heat pump is creating heat but there is not enough water going though the machine to carry the heat out into the pool. A Professional Heat Pump Manufacturer Since 1999 Tel: 0086-20-82181867 When I fire up the heater on Pool mode it begins to heat normally but after about 5-10 minutes (and even sometimes after 20 minutes) it moves over to Spa Heat mode (which I dont have a spa) and shuts down the heater. I agree. Clean entire filtering system and or replace filter element. Had a pump problem and had to replace pump motor. Yes, high flow rates can erode the heat exchanger. Any new postings here are unlikely to be seen or responded to by other members. Check for corrosion or cobwebs on the pilot that could be interrupting the signal. Automatic pool vacuum causing restrictionReclaim charge. Adjust all plumbing valves. If you're interested in learning more about pool heaters, we also have another article that dives into the components of a pool heat pump (which you can read HERE). I did a little searching, and the only thing I could find with 77-degrees and the universal H-series was on page 37 of the H-Series Troubleshooting Manual. Manufacturers equip swimming pool heaters with pressure sensors. You may use water at low pressure to thaw ice build up on the outer coil, shut the heater off when doing so. Deactivate power while routing wiring to control board. Water has always been in tip top shape. Make sure the filter has been cleaned/backwashed. 2023 Poolheatpumps.com. Thanks a bunch.
