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 contact 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).
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.
