Installation
STEP ONE
Place a screwdriver or similar object into the small slot located in the top of the 039. Push the screwdriver against the plastic tab and pull the top of the front cover so that it pivots around the bottom edge of the 039.

To Control
#6 1” screws
STEP TWO
The base of the 039 should be securely installed in the desired location. Mount the 039 directly to the desired location using two #6-1” screws. The screws are inserted through the mounting holes and must be securely fastened to the desired location. If possible, at least one of the screws should enter a wall stud or similar surface. If the 039 is to be mounted to a 2” x 4” electrical box, order an Adaptor Plate 007. This plate will mount to the electrical box and the 039 will then mount to the plate.

MOUNTING THE 039
STEP THREE
WIRING THE 039
Run 18 AWG twisted pair or similar wire between the 039 and the control. Insert the wires through the hole provided in the back of the 039 enclosure and connect them to the Com and tekmar Net™(tN2) terminals. Do not run the wires parallel to telephone or power lines as this may interfere with the operation of the 039. If the 039 wires are located in an area with strong sources of electromagnetic noise, shielded cable should be used or the wires can be run in a grounded metal conduit.
NOTE: Do not apply power to the 039. The 039 is to be wired directly to the control. The connection between the control and the 039 is polarity sensitive. The Com terminal of the 039 must be connected

to the appropriate terminal of the control. If the wires are reversed, the 039 will not function and the control will display a short circuit error for the tekmar Net™ (tN2) device.
STEP FOUR
INSTALLING THE FRONT COVER
Align the hinges on the bottom of the front cover with the bottom of the 039 mounting base. Pivot the front cover around the bottom hinges and push the top against the mounting base until it snaps firmly in place.
Settings
LIMITING THE TIME RANGE
The time range on the 039 can be limited in order to avoid extreme time settings or any tampering with the setting.
• Turn the dial until the desired time is at the bottom of the 039.
• Remove the front cover by following Step One of the Installation procedure.
Lift and pull the scale off the dial. Be careful not
to turn the dial while removing the scale. With the scale off, a series of small holes will be visible around the dial. Behind the dial there is a post which can be used to limit the rotation of the dial. Two aluminum limit pins are provided in the dial.
Holding Clip
SETTING A MINIMUM TIME LIMIT
Remove one of the limit pins and re-insert it into the hole that is slightly to the left of the post at the bottom of the dial. With the pin in place the dial should only rotate clockwise from its current position as the counter-clockwise rotation is now restricted by the pin.
The 039 can be used to set the desired running time of the snow melting system. Turn the 039’s dial until the desired running time is displayed in the window.
NOTE: If an infinite (NO LIMIT) run time is selected, the snow melting system runs continuously until WWSD or CWCO occurs, or someone presses the start / stop button on the 039.
