Cycle rate limits the maximum number of times the
system can cycle in a 1 hour period measured at a
50% load. For example, when set to 3 CPH, at a
50% load, the most the system will cycle is 3 times
per hour (10 minutes on, 10 minutes off). The
system cycles less often when load conditions are
less than or greater than a 50% load. The
recommended cycle rate settings are below for each
heating equipment type:
Standard Efficiency Gas Forced Air = 5 CPH
High Efficiency Gas Forced Air = 3 CPH
Oil Forced Air = 5 CPH
Electric Forced Air = 9 CPH
Hot Water Fan Coil = 3 CPH
Hot Water Radiant Heat = 3 CPH
Geothermal Radiant Heat = 3 CPH
Steam = 1 CPH
Gravity = 1 CPH
