Aux Reverse Staging ‒ Enables the second stage of the auxiliary heat to be run if the current temperature is greater than the value set for the Aux Stage 2 Temperature Delta setting. Answer: The tables below enlist different technical problems with Ecobee thermostats and provide possible solutions. Something I learned from ecobee while chatting on Facebook messenger: Once the AUX heat is engaged, It will try to complete the desire set point as the previous compressor cycle did not help satisfy the desire set point.

Installing ecobee with Multi-Speed Fan Systems. You can also control staging by using advanced setting options. Q1: Sometimes, when it is very cold (-10C to -12C), the compressor AND the the aux heat will run simultaneously as the compressor alone cannot maintain desired temperature.
