The Humidity & Temperature Sensor 086 can be connected to select tekmar
thermostats to remotely measure relative humidity and temperature. The 086
mounts flush or nearly flush to the wall to allow the sensor to visually blend in
with the surrounding wall.

Installation

Caution

Improper installation and operation of this control could result in damage to the
equipment and possibly even personal injury or death. It is your responsibility
to ensure that this control is safely installed according to all applicable codes and
standards. Please follow these step-by-step instructions to gain a full understanding
of this device.

Step One - Check the Contents

Check the contents of this package. If any of the contents listed are missing or
damaged, please refer to the Limited Warranty and Product Return Procedure on
the back of this brochure and contac t your wholesaler or tekmar sales representative
for assistance.

Type 086 includes • One Indoor Sensor 086 • One Installation and Operation
Manual D 086.

Step Two - Choosing a Location for the Sensor

The sensor should be installed on an interior wall of the desired zone to be
controlled. Avoid installing the sensor in a wall if the adjacent zone is at a much
different temperature. Do not mount the sensor in a location that may be affected
by localized heat sources or cold drafts (in direct sunlight or near a supply air
duct or window).

Step Three - Rough In Wiring

Before drywall is installed run four conductor 18 AWG wire from the tekmar
thermostat to the desired location of the sensor. The maximum wire length between
a thermostat and sensor is 500’ (152.4 m).

Do not run the wires parallel to telephone or power lines. If the sensor wires are
located in an area with strong sources of electromagnetic noise, shielded cable or
twisted pair should be used or the wires can be run in a grounded metal conduit. If
using shielded cable, one end of the shield wire should be connected to the Com
terminal on the thermostat and the other end should remain free. The shield must
not be connected to earth ground.

Staple the wire to a wall stud 5’ (1.5 m) above the floor and coil 1’ (0.3 m) of the
wire to work with before cutting it off.

Write down the exact location of the wire in the wall so it can be found when the
drywall is installed.

Step Four - Installing the Sensor

----------------------------------------------------

Once the drywall has been installed, locate the sensor wire behind the drywall
using your notes from Step Three.

Near Flush Mount

----------------------------------------------------

A. Using a hole-saw to drill a 1” (25.5 mm) hole at the location
of the sensor wire. Do not drill hole directly over stud.

B. Paint the wall.
C. Remove front disc sticker from the sensor.
D. The front disc of the sensor may be carefully hand painted.

The slotted grill holes must be kept open and free of paint.
Do not use a paint roller. Avoid allowing paint to enter the slotted
holes on the front disc of the sensor as permanent damage to
the sensor may result.

E. Pull the excess wire through the hole.
F. Follow the directions in Step Five - Wiring the Sensor.
G. Once wired, feed the excess wire back into the hole and

hand press the sensor until the back of the disk touches the
wall. The sensor is held in place by the taper of the enclosure
(no fasteners required).
