FAN SPEED SELECTION
The T8532OCC Thermostat has an onboard occupancy sensor that will setback operation when a room becomes vacant. Service Menu 325 Occupied Sensor Operation is turned on to enable this operation.
Occupied Timer (SM 326) – Sets the amount of time that must pass without detection before the control goes to Setback and starts the Ramping process.
Setback Ramping (SM 327) – Determines how the control will ramp to setback
values. The economy set goes directly to setback values. Comfort 1 setting will allow a 1°F per hour setback of the control set point. Comfort 2 sets back at 2°F per hour until the selected setback value is reached.
Setback Values (SM 310 and SM 320) – Set the HEAT and COOL set points for the setback. Values can be set to OFF or 50-90F. Selection of OFF will result in a set point of OFF.
Night Lock ON Protection (SM 328) – When enabled the control holds the user set point between 10 PM and 8 AM, anytime occupancy is detected during that time period. Note: This control has Low/ High Temp Protection. Freeze protection on this control is set at 40°F (heat). Over-temp protection is set at 110°F (cool).
