Configuring hysteresis
Hysteresis helps prevent damage to the relays, variable stages, and the equipment connected to them
by preventing the stages from switching on and off rapidly when the temperature is hovering close
to the set point.
Hysteresis is the number of degrees above the set point that a heating stage or relay switches off,
and the number of degrees below the set point that a cooling stage or relay switches off. For
example, a household thermostat might switch on a furnace at 68°F when the house is cooling
down, but switch it off at 70°F when the house is warming up. The difference between these two
values is the hysteresis.
There are separate hysteresis values for each zone. All equipment assigned to the zone is affected by
the zone’s hysteresis value.
Default: 1.0°F (0.5°C) Range: 0.3 to 5.0°F (0.2 to 2.8°C)
