EcoInsight Thermostat Installation Guide
Warning: Before beginning, remove power from all relevant electrical outlets by turning off any appropriate circuit
breakers. Lockout and label all circuits in accordance with local code and always test with appropriate meter that
power is off.
Section 1: Tools Needed
• Security screw wrench provided by Telkonet
• Phillips head screwdriver
• Minimum of two wall anchors, two wall dogs (four anchors recommended)
Section 2: Thermostat Installation
Open the EcoInsight by removing the security screw from the left side of the product using the security screw
wrench. Then press the lever next to the security screw and open the faceplate.
When mounting the EcoInsight, be sure the placement allows wiring to come through the large rectangular hole on
the left side of the backplate.
Mark placement for wall anchors or wall dogs (minimum of two anchors required, four recommended). Attach the
backplate to the wall by inserting the wall anchors in the marked areas, and screwing the backplate into the wall
anchors. Do not overtighten the screws in order to avoid bowing the backplate

Thermostat Backplate
• R (Power) is used for the main power supply.
o For high voltage installations, be sure to follow high-voltage safety procedures such as making sure
that the thermostat is inside an electrical box.
• C (Common) is used to connect the common wire.
• AUX (Auxiliary) connector can be used for several purposes, such as lighting control or a third fan speed.
• W1 (Heat)(Strip) is used for the Heat control.
• Switched Power 1 (W1/Y1) will connect to R as a same-voltage power supply, but is available as an
alternate voltage power supply if needed.
• Y1 (Cool)(Comp) will be used for cooling.
• G (Fan) will be used for the first fan speed, or the only speed when there is a single fan speed.
• (B)(G2)(Y2)(Changeover) is most often the second fan speed, but occasionally used to power a heat pump.
• Switched Power 2 (G/O/W2) is usually jumped to Switched power and/or R, but can be another alternate
power supply voltage.
• W2 (Y2)(G2)(G3)(Multi-speed) can be used for a second or third fan speed.
