Dehumidification Capability, Fan Control, and Occupancy Sensing Capability Installation Instructions

Note:
Allow for vertical air circulation to the
TEC22x6(H)-4 and TEC22x6H-4+PIR Series
Thermostat Controllers.
To install the thermostat:
1.
Use a Phillips-head screwdriver to remove the
security screw on the bottom of the thermostat
cover.
Note:
Normally, the security screw is packaged
separately in a plastic bag with the thermostat
controller. Skip this step if the screw is not installed
on the bottom of the cover.
2.
Pull the bottom edge of the thermostat cover and
open the thermostat as illustrated in Figure 1.
Note:
PIR models have a wiring connection
between the cover and the Printed Circuit Board
(PCB). This connection allows for proper wiring of
the occupancy sensor. Carefully remove the wiring
connection from the PCB by pulling up on the
connector block.
Do not attempt to remove the
connector block by pulling on the wires
3.
Carefully pull the locking tabs on the right side of
the thermostat mounting base and unlock the PCB.
Open the PCB to the left as illustrated in Figure 2.
4.
Pull approximately 6 in. (152 mm) of wire from the
wall and insert the wire through the hole in the
thermostat mounting base.
5.
Align the thermostat mounting base on the wall and
use the base as a template to mark the two
mounting hole locations.
6.
Position the thermostat mounting base so that the
arrow on the base points upward to indicate the top
of the thermostat.
Note:
If you need to install the thermostat 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) or
3 x 2 in. (76 x 51 mm) square boxes. This
procedure ensures that you have enough space for
cabling and end-of-line devices, if needed.
Note:
For surface-mount applications, use
durable mounting hardware such as Molly bolt
anchors that cannot be easily pulled out of the
mounting surface.
7.
Secure the mounting base to the wall surface using
two mounting screws as illustrated in Figure 3.
Note:
Be careful not to overtighten the mounting
screws.
