Heating / Cooling Interlock
Time Interlock
In order to prevent frequent changes between heating and cooling, the thermostat
has a Cooling Interlock setting. Once the Heat 1 relay has been off for a minimum of
one heating cycle or the length of the Cooling Interlock, (whichever is longer) cooling
is permitted
.
Temperature Interlock
When in the Auto mode, the cooling temperature is limited to 3°F (1.5°C) above the
heating temperature. If the cooling temperature is set below the heating temperature,
the thermostat automatically adjusts the cooling setpoint
.
When operating in the Cool mode, there is no interlock between the heating and cooling
temperature.
