Heating Cycle Rate Auxiliary Heat. Heat Pumps Explained What does everyone recommend for this setting on Honeywell thermostats with a heat pump and heat strip electric backups for aux? Honeywell recommends 9 in the manual but curious if a lower setting is better/more efficient as 9 seems high this is for a heat pump and a honeywell thermostat model: TH5220D Second stage heat cycle rate/ Auxiliary heat (CPH) 5 - For gas or oil furnaces of less than 90% efficiency 1 - For steam or gravity systems 3 - For hot water systems & furnaces of over 90% efficiency 9 - For electric furnaces.

What does everyone recommend for this setting on Honeywell thermostats with a heat pump and heat strip electric backups for aux? Honeywell recommends 9 in the manual but curious if a lower setting is better/more efficient as 9 seems high Should I leave the cycle rates at the default settings of 3 and 9, or change them to something else?
Thermal cycling profile for one cycle. A = dwell time; B = heating
I can see the argument made both ways that if it were at a setting of 9, it would give quick bursts of aux heat until it's the temp is within the range of. The thermostat has settings for the cycle rate for each stage Every heating system type will deliver heat to the house at a slightly different rate
Heat Rate Animation YouTube. These cycle settings don't kick in until the system starts achieving setpoint, so don't worry if it will shut off if it's set to 70° in heat mode and it's 60° in the house. A typical hot water system would cycle less then that
Heat Rate Animation YouTube. From what I've read 3 sounds right, but was wondering if it should be at "9 EMERGENCY HEAT" setting The system had been sold to me as one which would be silently and gently maintaining temperature on Low Speed mode (which truly is very silent, very nice).
