How to fix a brownout alarm on my Pentair Heat Pump?
- DdavisalexanderSep 4, 2025
To address a brownout alarm on your Pentair Heat Pump, start by checking the supply voltage to the transformer, it should be between 208 and 260 volts, and the transformer's output, which should be between 24 and 28 volts; replace the transformer if the output is below this range. Also, check the supply voltage to the heat pump, ensuring it's between 208 and 260 volts, and verify that there isn't a phase outage, with 120 volts to ground and 240 volts across power legs. If voltage issues persist, consider installing a boost transformer closer to the heat pump to maintain proper voltage levels.
