3.1 Editing setpoints for the cooling unit

Setpoints are the means by which cooling-unit operation is controlled.
NOTE: Setpoint adjustment is only available via the web-based UI (and the wall-mounted controller).
You cannot modify setpoints using the mobile app.
NOTE: The default minimum difference between heating and cooling setpoints is 5°F (2°C), and does
not allow the heating and cooling setpoints to be set inside this differential. To select setpoints for that
do not automatically adjust to the minimum difference, this differential must be zero. We recommend
that you set the differential to zero at system start-up. See
page 20.
To edit the setpoints:
1. Click
The SETPOINTS panel opens.
2. Adjust the setpoint options, then click Save.
The setpoint is updated.
