CAUTION
Improper installation and operation of this sensor could result in damage to equipment and possibly even personal injury. It is your
responsibility to ensure that this sensor 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 GETTING READY
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 contact your wholesaler or tekmar sales representative for assistance.
Type 084 includes • One Indoor Sensor 084 • One Data Brochure D 084.
STEP TWO CHOOSING A LOCATION FOR THE INDOOR SENSOR
The Indoor 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 084 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).
Installation
The tekmar Indoor Sensor 084 includes a 10 k thermistor mounted
on a white thermoplastic disk to provide an accurate measurement
of the indoor temperature. The 084 mounts flush or nearly flush to
the wall to give an unobtrusive look to the sensor. Since the sensor
material is corrosion resistant, drywall installers are able to mud
over the sensor or the 084 can be painted to match the existing
wall color. The 084 can be connected to a tekmar thermostat for
remote temperature sensing.
STEP THREE ROUGH IN WIRING
• • Before drywall is installed run two conductor 18 AWG wire from
the tekmar thermostat to the desired location of the Indoor
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 Indoor 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 terminals 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’ (.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.
