Installing the thermostat controller

1. Use a 1/16 in. (1.5 mm) Allen wrench or Johnson Controls
Tool (order separately) to remove the security screw if it is installed on the top of the
thermostat controller cover as illustrated in Figure 2.
2. Pull the top edge of the cover and open the thermostat controller as illustrated in Figure 2.
Important: The cover is not secured on the bottom. Be careful not to drop the cover.
Important: If you install more than one thermostat controller, keep track of which cover
attaches to which base. The controller version and the base version must match to ensure
proper operation.
Important: Use proper Electrostatic Discharge (ESD) precautions during installation and
servicing to avoid damage to the electronic circuits of the thermostat controller.
