Why is my Trane TCONT402AN32DA Thermostat heating cycle too fast or too slow?
If the heating cycle on your Trane Thermostat is too fast or too slow, resulting in a narrow or wide temperature swing, it might be influenced by the location of the control or the size of the heating system. Verify the cycle rate adjustment in ISU Steps 24, 26, 28, 30, and 32.
Why is my Trane Thermostat cooling cycle too fast or slow?
If the cooling cycle on your Trane Thermostat is too fast or too slow, resulting in a narrow or wide temperature swing, it may be influenced by the location of the control and/or the size of the cooling system. To address this, verify the cycle rate adjustment in ISU Steps 20 & 22.
What does it mean when my Trane Thermostat shows a solid service indicator and '--' in the temperature display?
If the Trane Thermostat displays a solid service indicator and "--" in the temperature display, it indicates that the indoor temperature sensor is either open or shorted. To resolve this, replace the control.
Why does my Trane Thermostat show '--' for outdoor temperature?
If the outdoor temperature display on your Trane Thermostat shows "--" and the Service indicator is on solid, it could be due to: * An open or shorted outdoor temperature sensor. Consider replacing the outdoor sensor. * Open or shorted outdoor sensor field wiring. Check and repair the outdoor sensor field wiring.
Why are the ROOM and SERVICE icons flashing on my Trane Thermostat?
If the ROOM and SERVICE icons are flashing on your Trane Thermostat while it continues to display the indoor room temperature, it means that the installer has selected a remote indoor sensor in ISU 36 but none is connected, a wire is broken/not connected, or the sensor has failed open. This control will default to the on-board sensor if a remote indoor sensor were hooked up and failed to report properly. Select the proper option for ISU 36, repair the wire or connection, or replace the sensor.
