Advanced Device Configuration
Control4 has enhanced the available Thermostat settings to allow users and installers to modify
engage and cutoff temperature deltas as well as maximum and minimum run time, off, and delay
times so that the Thermostat can be configured to run optimally with any HVAC system.
Note: Allowing such fine tuning of all settings can result in setting improper values and
combination of values to cause the HVAC system to run less than optimal. To prevent thrashing
the cool and heating engage (constant heat, then cool, engagement), cutoff and set points are
enforced to have at least a one (1) degree difference for engage temperatures.
The formula for the dependency of these values is:
Heat/cool engage delta—Opposite stage (if heat engage, then cool cutoff and visa versa) cutoff
delta + set points delta (cool set point – heat set point) >=1
