INSTALLATION & OPERATIONS GUIDE | MICROSET 4
Mounting
The Microset 4 is designed to be wall-mounted indoors, with dimensions ideal for mounting to a single-
gang electrical box. See Figure 11 on page 17.
Installation best practices
A building’s environment may introduce challenges when looking for the ideal installation location and
may also impact how a Microset 4 can be installed. For example, architects may not understand how
the placement of windows, doors, air registers, printers, and other equipment impact temperature
sensors. Or if a Microset 4 can be installed in an all-glass atrium without regard for the direction of the
sun.
Properly locate sensors
Sensor location impacts accuracy when sensing air temperature.
To meet requirements of the Americans with Disabilities Act, mount no higher than 48" from the floor
and with a minimum clear floor space of 30" X 48" (760 X 1220 mm). See Figure 1.

Mounting guidelines for compliance with Americans with Disabilities Act (ADA).
• Do not install the sensor where it will be exposed directly to solar radiation.
• Do not install the sensors into shelving or alcoves.
• Do not install near heat generating equipment, e.g. printers, coffee post, lamps, etc.
• Do not install adjacent to or behind doors.
• Never install behind curtains and/or blinds.
• When installing onto a solid wall (concrete, etc) always use insulated foam backing between the
backplate and the wall.
• Do not mount onto walls that conceal hot water pipes.
Diffuser airflow
Do not install sensors directly in line with the air flow coming from air distribution diffusers. Adjust the
diffusers to reduce air flow across the wall if you take a reading at the wall where the sensor is located
and it is greater than 30 fpm (9.14 mpm).
Prevent air infiltration
Prevent air from infiltrating through wire and screw holes in the Microset 4 backplate by affixing a
closed-cell foam barrier to the backplate. The foam covers all holes and provides a barrier between the
Microset 4 which prevents the effects of wall coupling. For more information about preventing air
infiltration, see “Optional foam accessory” on page 52.
