Heat Pump Malfunctioning Alarm
The Heat Pump Alert (iO-HPA) is like a nosy neighbor keeping an eye on your heat pump system. It monitors the “W” voltage signal, the temperature of the hot gas line, and will sound an alarm if the compressor isn't running after 12 minutes. No need to worry though – there's an alarm switch to silence that buzzer so you can tackle the problem even when you don't realize it's there. Keep your electric bill at bay with this heat pump failure detection system!
