Appendix A: Installation Troubleshooting
The most common problem is not knowing the thermostat operation. If the system is running a
heating or cooling cycle, the set point will turn red for heating and blue for cooling. When the
thermostat turns white, the heat pump, heat strip and furnace should all be off. The fan may continue to
run for a while after the cycle completes. If a fan is left in a manual mode, it will not shut off.
