Installing The Thermostat Controller - Johnson Controls TEC3330 Series Installation Instructions Manual

Installing the Thermostat Controller

1. Use a 1/16 in. (1.5 mm) Allen wrench or Johnson Controls® T-4000-119 Allen-Head Adjustment Tool (order
separately) to remove the security screw if it is installed on the top of the thermostat controller cover. See
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 are installing more than one thermostat controller, keep track of which cover attaches to
which base.
IMPORTANT: Use proper Electrostatic Discharge (ESD) precautions during installation and servicing to avoid
damage to the electronic circuits of the thermostat controller.

3. Align the thermostat controller mounting base on the wall with the security screw on the top and use the base
as a template to mark the two mounting hole locations. See Figure 3.
Notes:
• If you need to install the thermostat controller on an electrical junction box, use
2-1/2 x 4 in. (63 x 101 mm) square boxes with mud ring covers and avoid smaller 1-1/2 x 4 in.
(38 x 101 mm) square or 3 x 2 in. (76 x 51 mm) boxes. This procedure ensures that you have enough
space for cabling, if needed.
• For surface-mounted applications, use durable mounting hardware, such as wall anchors, that cannot be
easily pulled out of the mounting surface.
4. Pull approximately 6 in. (152 mm) of wire from the wall and insert the wire through the center hole in the
thermostat controller mounting base. See Figure 3.
5. Secure the mounting base to the wall surface using two mounting screws (user supplied) as illustrated in
Figure 3.
