Heat 1 CPH
(Heating cycle
rate stage 1)
1 - 12 CPH
This ISU is only displayed when Heat Stages is set to 1 stage or more stages. 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 (default) 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; Fan Coil = 3 CPH; Hot Water Radiant Heat
= 3 CPH; Steam = 1 CPH.

Heat 2 CPH
(Heating cycle
rate stage 2)
1 - 12 CPH
This ISU is only displayed when Heat Stages is set to 2 stages. The recommended (default)
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; Fan Coil = 3 CPH; Hot Water Radiant Heat
= 3 CPH; Steam = 1 CPH.
Aux Heat CPH
(Heating cycle
rate Auxiliary
Heat)
1 - 12 CPH
This ISU is only displayed when ISU 200 = Heat Pump and ISU 221=1. It is only displayed when
Auxiliary Heat is configured. 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.
