EcoSource Low Voltage Installation
Figure 21: EcoSource Backplate with Speed Nut and Drilled Hole
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 heat pump, ensure there is a jumper between Y1 and W1. See Figure 15 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 on page 20 illustrates sections of insulating tape on the
backplate, covering the wall opening.
Instructions Common to All Three Low Voltage Options
Step 41
Hook the thermostat to the hinges on the right side of the backplate, as shown Figure 22.
Figure 22-Line Up Hinges on Right
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 23) can be bent if too
much force is used.
