This ISU is only displayed when ISU 207 or
213 Backup Heat Stages is set to 1 stage.
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

The thermostat has a built in compressor
protection (minimum off timer) that prevents
the compressor from restarting too early after
a shutdown. The minimum-off timer is
activated after the compressor turns off.
If there is a call during the minimum-off timer,
the thermostat shows “Wait” in the display.

After the call for cooling ends, the thermostat
keeps the fan on for the selected amount of
time for increased efficiency. This may re-
introduce humidity into the living space.
