 4.1 MounngtheEZstat

For the most accurate performance, install the EZstat on an inside wall where it can sense the average room temperature.

Avoid locaons with direct sunlight, heat sources, windows, air vents, and air circulaon or obstrucons such as curtains,

furniture, etc.

The EZstat must not be:

• Mounted on an exterior wall.

• Mounted on or near an object with a large thermal mass such as a concrete block wall.

• Blocked from normal air circulaon by obstrucons.

• Exposed to heat sources such as lights, computers, copiers, or coee makers, or to direct sunlight at any me of the

day.

• Exposed to dras from windows, diusers, or returns.

• Exposed to air ow through connecng conduits or empty spaces behind walls.

• Install the supplied mounng base directly to a wall, a vercal electrical box, or a box with a wall plate kit.

• Roung the connecng cable or cables from the EZstat to the equipment it is controlling.

• If required, install an appropriate wall plate kit.

• Block leaks and airow from conduits with plumber’s puy or similar material.
