  • Page 29: Duty Cycles

    Operation Duty Cycles Indoor temperature control is achieved by duty-cycling the equipment when the load value is less than 100% of the current stage of operation. The duty cycle rate is dependent on the calculated load value. The illustration below shows the number of cycles at 50% load, for example, LV = 50. With all PI-based controls, the indoor temperature fluctuates above/below the user-selected setpoint to maintain comfort in the space.

  • Page 30: Staging Inhibits

    Operation Staging Inhibits When the stage threshold is exceeded, a stage inhibit is applied. The stage inhibit calculates the rate of recovery over a 10 minute period and determines if the next stage is required to meet the current demand. If the rate of recovery is great enough, a new 10 minute inhibit is enabled. The unit will not go to the next stage of operation until it determines that the current stage cannot satisfy the current demand.

  • Page 31: Modes

    Operation Modes System Mode The Pivot thermostat has five (5) system modes: • Heating; system only operates in heating mode. • Cooling; system only operates in cooling mode. • Off; system does not operate in either heating/cooling modes. • Emergency Heating; system operates only the indoor heat source. Note: Only available when the outdoor unit type is a heat pump.

  • Page 32: Fan Mode

    Operation Fan Mode The Pivot thermostat has two (2) fan modes: • Auto; fan runs only with a call for heating or cooling. • On; fan runs continuously while in occupied mode. In unoccupied mode the fan will only run when there is a call for heating or cooling.

  • Page 33: Advanced Operation

    This option is enabled by navigating to Installer Settings > Comfort Settings > Smart Continuous Fan. • Airflow reduction (applies only to Trane residential variable speed blowers) – If BK is connected, the unit can reduce the system airflow by 30% anytime the indoor RH is higher than the cooling RH target.

  • Page 35: Lockouts

    Advanced Operation Note: An outdoor temperature sensor must be enabled for lockout settings to be available. Lockout options are set by navigating to Installer Setup > Lockout Settings. Lockouts The Pivot thermostat lockout methods are: • Auxiliary heat lockout – When enabled, select an outdoor temperature which disables auxiliary heat anytime the outdoor temperature is above the selected temperature.

  • Page 36: Optimal Start/Stop

    Advanced Operation • RH control – Dry contacts are closed anytime the indoor humidity is less than the heating target relative humidity. • Frost control – The unit references the outdoor temperature through a wired outdoor air temperature sensor and structure integrity to offset the heating target relative humidity. This helps to limit the risk of frost or condensation from forming on interior walls and windows.

    Aux output will be on during occupied periods, and off during unoccupied periods, and therefore will act as an occupancy output signal, Refer to figure 5 in the Wiring section for an example of a typical Trane installation. Warm Air Discharge Enabling warm air discharge with BK connected reduces the variable speed blower airflow by 20% when in compressor heating operation.
