FAQS
B. TROUBLESHOOTING
1. I am running out of hot water. How can I increase hot water recovery?
Increase the set temperature, make sure it is in Auto Mode, and change the kick-in differential to a lower number.
2. How can I check if the heat pump is running?
When the heat pump is running, the HTG icon will be lighted on the display panel.
3. How can I check if the electric element is running?
When the electric element is running, the HTR icon will be lighted on the display panel.
4. How can I check if the heat pump is operating normally?
A healthy heat pump that is working properly will be quiet. One of the main ways you can tell if your heat pump is
working well is to listen to it. You should be able to hear it when it turns on, when the fans start and stop working and
when air passes through the ductwork, but the pump itself should be relatively noiseless. There should be no groaning,
creaking, or popping sounds. The motors should not sound as though they are working too hard or straining to
complete a task.
