TEC2604-4 and TEC2604-4+PIR BACnet® MS/TP Networked Multi-Stage Economizer Thermostat 
Controllers Installation Instructions

2

Note:

Allow for vertical air circulation to the 

TEC2604-4 or TEC2604-4+PIR Thermostat Controller.

To install the thermostat controller:

1.

Use a Phillips-head screwdriver to remove the 
security screw if it is installed on the bottom of the 
thermostat controller 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 controller 
cover and open the thermostat controller 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 controller 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 controller mounting base.

5.

Align the thermostat controller mounting base on 
the wall and use the base as a template to mark 
the two mounting hole locations.

6.

Position the thermostat controller mounting base 
so that the arrow on the base points upward to 
indicate the top of the thermostat controller.

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) 
square or 3 x 2 in. (76 x 51 mm) boxes. This 
procedure ensures 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 base to the wall surface using two 
mounting screws as illustrated in Figure 3.

Note:

Be careful not to overtighten the mounting 

screws.
