Operation Manual

Location of the Sensor

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

The location of the snow/ice sensor determines how well the snow melt detector

responds to conditions on the snow melting slab. The sensor measures the

temperature of the slab surface, and would normally be installed in a location that

is representative of the average surface temperature and moisture conditions. The

only exception to this practice would be those applications where the sensor is

placed in a specific problem area where ice or snow often forms first.

The installer should be careful to place the sensor in a location where it will not be

affected by abnormal temperature conditions that may occur near buildings, hot air

exhaust ducts or other heat sources, or sunny areas within a larger slab area.

As well as reading temperatures, the sensor also detects surface water. The installer

should be careful not to place the sensor where standing water could accumulate

on its surface. Standing water in the socket may cause the snow melt system to

be held on far longer than necessary, as the control will be getting a signal that

water is present even though the rest of the slab surface may be dry. In addition,

the sensor should not be placed in areas where drainage is considerably better

than the surrounding area.

The snow/ice sensor should not be installed in locations where vehicles park,

near building overhangs or near trees since this may interfere with snow fall

accumulation. If in doubt about the location of these obstacles, a second spare

socket and conduit can be installed in order to provide a backup sensor location.

Some tekmar Snow Melting Controls are capable of dual sensing. To determine if

this feature is available, refer to the Installation & Operation Manual for the tekmar

Snow Melting Control.

•

Read this Manual BEFORE using this equipment.

Failure to read and follow all safety and use information can result in

personal injury, property damage, or damage to the equipment.

Keep this Manual for future reference.

It is your responsibility to ensure that this sensor is safely installed according to all

applicable codes and standards. tekmar is not responsible for damages resulting

from improper installation and/or maintenance.

Step 2 - Sensor Installation

Step 1 - Check the Contents

3 of 8

Vehicle tire and pedestrian traffic can track water and contaminants onto the snow

melt area. If the snow/ice sensor is located in the traffic area, snow melting will be

triggered by the passing traffic. This may be desirable in commercial areas where

excessive traffic can cause the surface to become icy. In residential installations, the

amount of traffic is usually limited, and it may be desirable to locate the snow/ice

sensor away from the traffic area. This will reduce the number of snow melt events

that occur and thereby reduce the annual fuel consumption.

Locate the sensor midway between the heating pipes or elements.

Conduit

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

Place the sensor socket at the chosen location and run a conduit for the cable from

the socket to the snow melting control. If more than the included length of cable is

required to reach the control, run the conduit to a weatherproof junction box. The

sensor cable should be run in its own conduit and not in combination with high

voltage wiring.

The conduit length from the sensor to the junction box should be less than the length

of cable supplied with the snow/ice sensor.

At the junction box, additional 18 AWG, 5 conductor cable can be spliced on to

increase the total length to 500’ (150m) from the sensor to control.

Avoid tying the conduit to the rebar within 6’ (2m) of the socket. This allows the rebar

grid to move without disturbing the position of the socket.

•

The top of the snow/ice sensor should be flush and parallel

to that of the snow melt surface.

When the sensor is installed on a sloped driveway, the sensor

must be installed near the lowest elevation of the slope. This

is required since the melting snow or ice runoff water will

drain toward the lowest point on the driveway and keep this

area wet for longer periods of time.

A mounting plate has been included to simplify the

installation of the sensor socket. When possible, the

mounting plate should be located directly on top of gravel

in order to provide good drainage. If the slab is more

than 4" thick, a mound of crushed rock or a styrofoam or

wooden block can be used to elevate the socket. A hole

must be punched or drilled in the styrofoam or wooden

block in order to provide drainage.

Failure to provide adequate drainage under the socket

may reduce the life expectancy of the snow/ice

sensor.

The mounting plate can be fastened to the ground by

driving 1/2" (12.7mm) rebar through the four holes located

on each of the four corners and then tying the mounting

plate to the rebar.

1. Cut four pieces of rebar at least 12" (300mm) long.

2. Drive the rebar into the ground through each of the mounting plate rebar

holes. Leave approximately 2" (50mm) of rebar above the ground.

Cut several 12

(300mm) pieces of steel wire.

4. Form a “U” shape and pull wire through the rebar tie hole from the bottom

to the top side.

5. Repeat by pulling the “U” shape from the top to the bottom side.

6. Repeat (4) and (5) for each of the four corners.

7. Cross the wire, then wrap around the rebar.

8. Twist wire using pliers to tighten.

The mounting plate also has conduit tie holes to allow a cable tie or steel wire to

fasten the conduit to the mounting plate.

Placing Concrete

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

A plastic plug is provided with the socket to prevent it from being accidentally filled with

concrete. The plastic plug is the same thickness as the sensor flange. This allows the

finished surface of the concrete (asphalt, etc.) to be troweled flush with the plug. The

plug must be installed prior to placing the concrete. Also ensure that the mounting

plate drainage hole remains unplugged once the concrete has cured.

Installing Brick Pavers

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

If using brick pavers instead of concrete, it is recommended to mortar surrounding

brick pavers to the side of the socket. This ensures good thermal conduction from

the brick pavers to the socket. The top of the brick pavers should be level with the

socket when the plastic plug is installed.

Install the Sensor and Cable

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

When the snow melt surface is finished,

remove the plastic plug from the socket

and fish the cable through the conduit until

there is only 6 to 12"(150 to 300mm) of

cable between the sensor and conduit.

Loop this remaining extra wire in a loose

coil so as to not twist it, and place it, and

the sensor into the socket. Secure the

sensor to the socket with the four screws

provided, making sure the “O” ring is in

place and properly seated.

Placement in Existing 091 Socket

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

Current versions of the Snow/Ice Socket 091 use #6-32 screws. Previous versions

of the 091 used smaller #4-40 screws. When replacing an 090, both sets of screws

are provided. It is recommended to try the smaller screws first to avoid cross

threading.

Salt and Brine Contamination

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

The performance of the snow/ice sensor water detection can be compromised

when exposed to de-icing agents such as road salt, magnesium chloride, or calcium

chloride. These contaminants can permanently damage the sensor. It is recommended

to locate the sensor away from areas exposed to these deicing agents when at all

possible. Locations to avoid could include tire track areas or areas close to a curb

where traveling vehicles may splash contaminated water on to the sensor.

Maintenance

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

The Snow/ Ice Sensor is installed in a harsh environment. Accumulation of dirt, salty

grime, etc., on its surface will inhibit proper water detection. It should be checked

on a regular basis and, when necessary, cleaned. Before cleaning, the control

power should be shut off to prevent the control from entering the snow melt mode.

Next, use a soft bristle brush and warm soapy water to clean the sensor surface.

Do not use a steel wire brush as this will damage the sensor. Use a paper towel to

thoroughly dry the sensor surface. After cleaning, re-power the control.

Snow Melting

Control

The snow/ice sensor cable has 5 wires: Red, Black, Blue, Yellow, and Brown. The

wires connect to the respective Red, Black, Blue, Yellow and Brown terminals on the

tekmar Snow Melting Control.

Step 3 - Electrical Connections

When performing these tests:

The sensor head should be installed in the slab.

The five cable wires at the control should be disconnected.

Use a good quality electrical testing meter with an ohm scale range of 0 to

2,000,000 Ohms.

The sensor has two 10k Ohm thermistors. One reads slab surface temperature, and

the other checks sensor heater temperature.

If the sensor has been disconnected from the control for an hour or more, the readings

for both thermistors should be very close.

Using the ohmmeter and standard testing practices, measure the resistance

between:

(a) the yellow and black sensor wires (sensor temperature), and

(b) the brown and black sensor wires (slab temperature).

The table below lists the expected resistance values at various sensor temperatures.

Measure the resistance between the blue and black wires. When the sensor surface

is dry, the reading should be 2,000,000 Ohms. When the sensor surface is wet it

should be between 10,000 and 300,000 Ohms.

Measure the resistance between the red and black wires of the heating element. This

reading should be close to 50 Ohms.

A Watts Water Technologies Company

The Outdoor Sensor 070 provides accurate measurement of the outdoor air temperature.

Many controls and thermostats can connect to the 070 to measure and display the

outdoor temperature.

STEP ONE

MOUNTING THE SENSOR

NOTE: The temperature sensor (thermistor) is built into the 070 enclosure.

• Remove the screw and pull the front cover off the sensor enclosure.

• The 070 can either be mounted directly onto a wall or a 2” x 4” electrical box. When

the 070 is wall mounted, the wiring should enter through the back or bottom of the

enclosure. Do not mount the 070 with the conduit knockout facing upwards as rain

could enter the enclosure and damage the sensor.

• In order to prevent heat transmitted through the wall from affecting the sensor read-

ing, it may be necessary to install an insulating barrier behind the enclosure.

• The 070 should be mounted on a wall which best represents the heat load on the

building (a northern wall for most buildings and a southern facing wall for buildings

with large south facing glass areas). The 070 should not be exposed to heat sources

such as ventilation or window openings.

• The 070 should be installed at an elevation above the ground that will prevent

accidental damage or tampering.

STEP TWO

WIRING AND TESTING THE SENSOR

• Connect 18 AWG or similar wire to the two terminals provided in the enclosure and

run the wires from the 070 to the control. Do not run the wires parallel to telephone

or power cables. If the sensor wires are located in an area with strong sources of

electromagnetic interference (EMI), shielded cable or twisted pair should be used

or the wires can be run in a grounded metal conduit. If using shielded cable, the

shield wire should be connected to the Com terminal on the control and not to earth

ground.

•

Follow the sensor testing instruction in this brochure and connect the wires to the

control.

• Replace the front cover of the sensor enclosure.

A good quality test meter capable of measuring up to 5,000 k (1 k = 1000) is required to

measure the sensor resistance. In addition to this, the actual temperature must be measured

with either a good quality digital thermometer, or if a thermometer is not available, a second

sensor can be placed alongside the one to be tested and the readings compared.

First measure the temperature using the thermometer and then measure the resistance of

the sensor at the control. The wires from the sensor must not be connected to the control

while the test is performed. Using the chart on the following page, estimate the temperature

measured by the sensor. The sensor and thermometer readings should be close. If the test

meter reads a very high resistance, there may be a broken wire, a poor wiring connection

or a defective sensor. If the resistance is very low, the wiring may be shorted, there may

be moisture in the sensor or the sensor may be defective. To test for a defective sensor,

measure the resistance directly at the sensor location.

Do not apply voltage to a sensor at any time as damage to the sensor may result.
