Typical temperaturetime profile of continuous heating cycle without

Heating Cycle Rate Auxiliary Heat. M11Q2 Heating Curves and Phase Diagrams Chem 103/104 Resource Book The T8411R Thermostat provides 24V control of a two-stage heating and one-stage cooling heat pump system with manual • Selectable second-stage heating cycle rate (3, 6 or 9 changeover from heat to cool and second stage auxiliary heat. Rick Mather : The cycling rate provides you with the flexibility to set the cycle rate adjustment to match your specific heating system, whether it is gas or oil forced air, high efficiency forced air, electric forced air, or baseboard hot water.

Most controls and thermostats will have some sort of cycle rate per hour setting that kicks in to prevent over-cycling once the setpoint is reached Thanks for the help and guidance! Adam Upvote #2 03-02-13, 01:06.

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. Rick Mather : The cycling rate provides you with the flexibility to set the cycle rate adjustment to match your specific heating system, whether it is gas or oil forced air, high efficiency forced air, electric forced air, or baseboard hot water. There appear to be 3 heat cycle rate settings for this thermostat so maybe these need to be adjusted? Function 5: Heating Cycle Rate, what should this be set to?

Heating and Cooling Curves ( Read ) Chemistry CK12 Foundation. 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. The thermostat has settings for the cycle rate for each stage

Why phase transition temperature via DSC during heating cycle is higher. Should I leave the cycle rates at the default settings of 3 and 9, or change them to something else? The heating cycle rate on the stat was set to "3" as per the recomendation in the installation manual (stating 3 was for furnaces over 90% efficiency)
