3000 Deadband
2° F to 9° F (in 1° F increments)
3° F Both No This ISU is only displayed when ISU 3000 is set
to Automatic.
Deadband is the minimum separation between
heat and cool settings when the thermostat is
setup for Auto Changeover. For example, if the
deadband is set to 3° F and the cool setpoint is
75° F, the warmest heat setpoint allowed would
be 72° F. If the heat setpoint is adjusted above
72° F, it will automatically adjust the cooling
setpoint higher to maintain the 3° F deadband.
When ISU 9070 (Dehumidification - Over
Cooling Limit) or ISU 9100 (High Humidity
Comfort Reset Setting) is set to 1, 2, 3, 4 or 5°
F, the thermostat will not show the full
Deadband range. For example, if you set a
Deadband of 3° F and an Over Cooling Limit of
2° F, the minimum Deadband that you can
select will be 5 F. This prevents the heating
system from turning on when the thermostat
over cools to reach the dehumidification
setting.
