Step 32 Level the backplate using a pen level across the bottom of the backplate.
Step 33 Place the speed nut on the backplate in the position shown in Figure 21, with the prongs
pointing inward toward the mud ring.
Step 34 Place the screw in the speed nut hole.
Step 35 Drive the screw into the mud ring. Use your fingers to hold the speed nut in place, to
prevent it from turning as the screw is driven. (The curve of the speed nut allows the
head of the screw to be slightly recessed into the backplate.)
Step 36 Mount the other screw in the hole on the right side of the backplate.
Step 37 Starting at the bottom of the terminal block and working up, use a precision screwdriver
to secure each of the wires into the appropriate pins on the terminal block. For low
voltage, using 20-18 gauge wire, leave a minimum of 8” of wire exposed from the wall for
connection directly to the thermostat’s backplate WECO terminals.
Step 38 Low voltage only: ensure backplate has appropriate jumpers between R, SW1 and SW2. If
installing on a head pump, ensure there is a jumper between Y1 and W1
2
. See Figure 15:
Backplate with Appropriate Jumpers on page 16.
Step 39 Verify each wire is secure by gently tugging on it.
Step 40 Ensure no airflow from the JBOX or wall cavity is able to seep into the thermostat through
the wire harness. Telkonet recommends the use of UL caulk or UL rated insulating tape to
avoid false temperature readings. Figure 20: Backplate with UL-Rated Insulating Tape on
page 4 illustrates sections of insulating tape on the backplate, covering the wall opening.
Steps Common to all Installation Methods
Step 41 Hook the thermostat to the hinges on the right side of the backplate.
Step 42 Line up the hinges on the thermostat to the notches on the backplate. Press the right side
of the thermostat tightly against the back plate.
Caution: when replacing thermostats, the metal pins (as shown in Figure 22) can be bent if too
much force is used.

If the Voltage for controlling any of the HVAC elements will be different than the voltage which is powering the
thermostat, you must remove the Jumper from R to Switched Power 1. You must then connect the supply voltage
being used directly into Switched Power 1 and Switched Power 2 if they are different. For example, if a new 24VAC
Transformer is added just to power the thermostat because the existing one is too small, it would be connected to R
and the existing transformer used for the control signals would be connected to Switched Power 1 and 2.
