The Snow Sensor 095 is an aerial mounted sensor that detects falling snow and
allows a tekmar Snow Melting Control 653 or 654 to automatically start the snow
melting equipment. System stop is provided by the control’s timer or by manual
disable. The 095 mounts to a nominal 1/2” (16 mm) metal or PVC conduit or pole. The
095 is well suited for adding automatic start to an existing snow melt system.
For use with tekmar Snow Melting Control type: 653 or 654

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 the installer’s
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 1 - 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 095 includes • One Snow Sensor 095 • One Installation and Operation
Manual 095_D.
Step 2 - Choosing a Location for the Sensor
The sensor should be installed outside on a nominal 1/2” (16 mm) PVC or rigid
metal conduit pole either on a roof or to the side of the snow melting surface. The
sensor must be located away from trees, building overhangs or other locations
that may interfere with falling snow. Avoid installing in locations where the sensor
may be vandalized. It is best to point the front face of the sensor in the direction
of any prevailing wind.

Step 3 - Rough In Wiring
Step 4 - Disassembly
Install a nominal 1/2” (16 mm) PVC or metal conduit from the tekmar Snow Melting
Control to the chosen sensor location. Pull 4 conductor 18 AWG wire from the
sensor location to the control location through the conduit. The maximum wire
length between the sensor and the control is 500’ (150 m).
If using PVC conduit, 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. If using shielded cable, one end
of the shield wire should be connected to the Com terminal on the Snow Melting
Control and the other end should remain free. The shield must not be connected
to earth ground.
1. Remove the outer ring by pulling up on the three catches.
2. Remove the three screws.
3. Remove the blue sensor disk from the sensor enclosure.
Avoid scratching any part of the surface of the blue sensor disk.
Scratches will result in corrosion not covered by warranty.
Step 5 - Painting the Sensor
The sensor enclosure is made of an off-white plastic material that is UV stable.
The plastic enclosure may be spray painted to match the color of the building. Do
not paint the blue sensor disk as this will damage the sensor.
