Control Response Rate
Note: Installer Setup is located under the Service Menu. Navigate to Home > Menu > Service >
Technician Access (press for 5 seconds) >Proceed > Service Menu > Installation Wizard or
Installer Setup.
Control response rate provides the capability of selecting a set of higher proportional-integral control
constants to increase the responsiveness of the unit. Selecting fast will cause the unit to generate load
value as a faster rate. Control response rate is adjusted by navigating to Installer Setup > Comfort
Settings.
Dehumidification
Dehumidification is enabled/disabled by navigating to Installer Setup > Comfort Settings.
The Pivot thermostat uses the following methods of dehumidification:
• Over-cooling
– If cooling is enabled, the unit will allow 0.1°F of over-cooling for each 1% of RH error. A
maximum amount of over-cooling can be configured for 1°F, 2°F, or 3°F. When the system is
actively over-cooling, Dehumidifying displays on the unit home screen. The maximum amount
of over-cooling is configured by navigating to Installer Setup > Comfort Settings. Refer to the
following example.
• Smart continuous fan
– If enabled, continuous fan operation interrupts when indoor RH exceeds desired cooling RH
target. A humidity icon displays along with the fan icon to indicate that continuous fan operation
has been disabled due to high humidity conditions. Smart continuous fan will not interrupt the
fan circulate mode. 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. Airflow reduction is disallowed if the indoor temperature is
more than 2°F above the cooling setpoint. Dehumidification is factory enabled by navigating to
Installer Setup >Comfort Settings. All Fan Off delays are also defeated when dehumidification
is enabled and the indoor RH exceeds the cooling RH target.
Dehumidification System Operation
The Pivot thermostat is capable of enabling the dehumidification system through the normally open
(NO) dry AUX contacts on the unit sub-base. Control options are:
• Stand-alone operation
– Dehumidifier operates independently from cooling operation as long as the unit is in cooling or
auto mode and the last call is for cooling. When selecting stand-alone operation, the unit allows
the selection of whether the indoor fan operates with the dehumidifier request.
