Description
Limits the number of cooling cycles every hour. If this value is 3
(default) for example, a cooling cycle can be invoked once in
each of the three 20-minute hourly intervals. In this example, a
subsequent call for cool after the initial cool call in a 20-minute
interval is deferred until the start of the next 20-minute interval.
This feature can be defeated by the user if changes are made to
override the setpoint settings, either at the thermostat or via the
Web page. This feature only applies to scheduled temperature
settings.
Disabled – This feature is disabled and unlimited cooling
cycles are allowed.
1-6, 10, 12 – The allowable number of cooling cycles per
hour.
Limits the number of heating cycles every hour. If this value is 5
(default) for example, a cooling cycle can be invoked once in
each of the five 12-minute hourly intervals. In this example, a
subsequent call for heat after the initial heat call in a 12-minute
interval is deferred until the start of the next 12 minute interval.
This feature can be defeated by the user if changes are made to
override the setpoint settings, either at the thermostat or via the
Web page. This feature only applies to scheduled temperature
settings.
Disabled – This feature is disabled and unlimited heating
cycles are allowed.
1-6, 10, 12 – The allowable number of heating cycles per
hour.
Select a relative humidity value from 10% to 90%. when
Enabled. When the measured RH rises above a preset threshold,
the HVAC cooling cycle is initiated. The cycle continues until
the humidity level falls 5% below the trigger level or until a heat
setpoint is encountered. When a heat setpoint is encountered, the
HVAC heating cycle is invoked. After the heat setpoint has been
satisfied, the HVAC cooling cycle (to satisfy humidity
requirements) is delayed for 5 minutes. Humidity control is
intended for moderate moisture control. High humidity
environments should also include secondary dehumidification
equipment.
Disabled – This feature is disabled and the A/C system may
not be used to reduce humidity.
Enabled – 10% – 90% - Humidity threshold expressed in
5% increments.
