(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. Do not drop the cover.
Important: If you are installing 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
correct operation.
Important: Use correct Electrostatic Discharge
(ESD) precautions during installation and
servicing to avoid damage to the electronic
circuits of the thermostat controller.

TEC3000 Series Proportional Fan Coil Thermostats Installation Guide
- If you need to install the thermostat
controller on an electrical junction box,
use 2-1/2 in. x 4 in. (63 mm x 101 mm)
square boxes with mud ring covers and
avoid smaller 1-1/2 in. x 4 in.(38 mm x
101 mm) square or 3 in. x 2 in. (76 mm 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.
