Mounting Standard and Digital Zone Temperature Sensors

• areas near heat sources like equipment (appliances, computers, copiers,
etc.) or concealed pipes or chimneys
• dead spots behind doors, draperies, or in corners.
Mounting Standard and Digital Zone Temperature
Sensors
Zone temperature sensors consist of two basic pieces: the base and cover.
Externally adjustable versions have an external adjustment knob. To remove
the sensor cover from the base:
1 Note the position of the adjustment knob (if present).
2 Use a small screwdriver to gently pry the adjustment knob from the
cover.
3 Before mounting a zone temperature sensor, remove zone sensor cover
by easing the tip of a small screwdriver between the base and the cover.
Gently lift the top of the screwdriver up. Do not force.
Follow these steps to replace the zone temperature sensor cover and (if
present) adjustment knob after mounting:
1 Align the cover with the sides of the base.
2 Press the cover toward the wall until it snaps into place.
3 Align the knob to the position noted prior to its removal.
4 Push the stem through the cover hole until the stem sits firmly in setpoint
potentiometer.
5 Turn the knob to assure that it rotates freely through the entire range of
temperature settings.

Wall Mount

With the cover removed, feed the control wires through the rectangular
opening in the base. Follow these steps if mounting the sensor to a wall:
1 Assuring that the base is level, position the back of the base over the wire
entry in the wall.
2 Mark the centers of the two oblong mounting holes, then set aside the
base.
3 Drill a 3/16 in. diameter hole approximately 1 in. deep at the marked
locations.
4 Insert plastic anchors into the holes until they are firmly seated.
5 Feed the control wires through the base and fasten the base to the wall
with the supplied mounting screws.
6 Connect the control wires to the proper terminals on the temperature
sensor (See Figure 15).
7 Replace the sensor cover.

Junction Box Mount

1 With the cover removed, feed the control wires through the rectangular
opening in the base.
