.
The thermostat automatically defaults to
the recommended setting for Geothermal
Radiant Heat (3 CPH).
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.
