Installation - Outdoor Sensor PM-070
Step One
Mounting The Sensor
NOTE:
The temperature sensor (therm-
istor) is built into the PM-070 enclosure.
• The PM-070 can be mounted directly
onto a wall and the wiring should
enter through the back or bottom
of the enclosure. Do not mount the
PM-070 with the conduit knockout
facing upwards as rain could enter the
enclosure and damage the sensor.
• In order to prevent heat transmitted
through the wall from affecting the
sensor reading, it may be necessary
to install an insulating barrier behind
the enclosure.
• The PM-070 should be mounted on
a wall which best represents the heat
load on the building (a northern wall
for most buildings and a southern fac-
ing wall for buildings with large south
facing glass areas). The PM-070
should not be exposed to heat sourc-
es such as ventilation or window
openings.
• The PM-070 should be installed at an
elevation above the ground that will
prevent accidental damage or tam-
pering.
