Where to Locate ECY-STAT thermostats
When installing the ECY-STAT, it is important to ensure that distances and obstructions do not impede
transmission. Metallic parts, such as steel reinforcement in walls, machinery, office furniture, etc. are
major sources of field strength dampening. Furthermore, supply areas and elevator shafts should be
considered as complete transmission screens, see following figure.

Transmission Obstructions and Interference

One way to get around an obstruction, such as a duct, is to place the ECY-STAT on the side of the ob-
struction that is nearer to the coordinating wireless device, even if the controller is on the opposite side
of the obstruction. But always keep in mind that the ECY-STAT performs best when it is away from
metal objects or surfaces (more than 1" (2.5 cm)).
In addition to obstructions, the angle with which the transmission travels through the obstruction has a
major influence on the field strength. The steeper the angle through an obstruction, the radio wave has
to travel through more material resulting in the field strength reduction (See figure below). Therefore, it
is preferable that the transmission be arranged so that it travels straight and perpendicularly through
the obstruction.

A solution to avoid an obstruction is to add another wireless router located closer to the controller(s).
