The following brochure describes how to wire the tekmarNet®4 (tN4) Timer 033. The 033 has one dry relay contact that
opens or closes based on the programmable schedule. The relay can be connected to the UnOccupied switch input on a
tekmar control or to other third party equipment. The 033 uses communication to indicate the schedule to a tN4 system.

Mounting the Timer
If a single gang switch box is used, an Adaptor Plate 007
is required to mount the Timer to the box.
Fasten the base of the Timer to the adaptor plate.
Feed the wiring through the openings in the back of the
adaptor plate and Timer.
Use the upper and lower screw holes to fasten the
adaptor plate to the box.
•
•
•
Remove the Wiring Cover:
To remove the wiring cover:
Place a small slot screwdriver or similar tool into the slot
located on the top of the Timer.
While pushing against the plastic tab, pull the top of the
front cover so that it pivots around the bottom edge of
the Timer’s base.

The electrical drawing examples on the following
pages show the 033 in common applications. Choose
the drawing that most accurately depicts the components
in your system and use that drawing as a guide to aid in
wiring your system.

For non-tN4 systems the tN4 terminal can be left empty.
On tN4 systems wire the tN4 communication to terminals
tN4 and C.
If a Zone Manager is used:
Connect the tN4 on the Timer to any available tN4 on
the Zone Manager.
Connect the C on the Timer to any available C on the
Zone Manager.
Note: This does not need to be repeated if the Timer is
powered by the Zone Manager, as long as the tN4, C,
and R have all been connected to the same zone, or the
same bus.

tN4 Communication Terminals 1, 2
On tN4 systems, Relay 1 is not required and the terminals
can be left empty.
On non-tN4 systems, wire the relay contact to the switch
terminals on the control system that will cause the
control system to change status (ie. go from Occupied to
Unoccupied).
Use these terminals as a switch to operate the setback
schedule for the control system.

Manager.
If a 24 V (ac) transformer is used:
Connect C on the Timer to C on the transformer.
Connect R on the Timer to R on the transformer.

Troubleshooting the Wiring
The following tests are to be performed using standard
testing practices and procedures and should only be carried
out by properly trained and experienced persons.
A good quality electrical test meter, capable of reading from
at least 0-300 V (ac), 0-2,000,000 Ohms, and testing for
continuity is essential to properly test the wiring.
General
Testing the Wiring
Testing 24 V (ac) Power Supply
1. Remove the front cover from the Timer.
2. Use an electrical test meter to measure (ac) voltage between the R and C terminals. The reading should be
24 V (ac) +/– 10%.
3. Install the front cover.
1. Navigate to the schedule menu that the Relay uses.
(Schedule 1 to 4)
2. Remove the front cover from the Timer.
3. Disconnect the wires from the relay contact.
4. Use an electrical test meter and check for continuity
across the relay.
If Switch 3 is set to NO, the Sleep or UnOcc segments
will display when continuity is present.
If Switch 3 is set to NC, the Wake or Occ segments will
display when continuity is present.
5. Reconnect the wires to the relay.
6. Install the front cover on the Timer.

The symbol is shown on the display when communication
is present. If the timer is connected in a network and the
communication is missing, there may be an open or short
circuit on the tN4 and C bus wires.
1. Remove the front cover from the thermostat.
2. Test the wiring for short circuits:
a. Disconnect the tN4 bus wires on one end.
b. Install wire nuts on each wire to ensure the wire ends
are not touching.
c. Disconnect the tN4 bus wires on the other end.
d. Measure for continuity using an electrical meter.
e. If continuity is present, there is a short circuit fault
along the wires. It is recommended to replace the
tN4 bus wires.
Testing the tN4 Network
3. To test for open circuits:
a. Disconnect the tN4 bus wires on one end and connect
them together.
b. Disconnect the tN4 bus wires on the other end.
c. Use an electrical meter to measure for continuity.
d. If there is no continuity, there is an open circuit fault
along the wires. It is recommended to replace the tN4
bus wires.

Technical Data
The installer must ensure that this control and its wiring are isolated and/or shielded from strong sources of electromag-
netic noise. Conversely, this Class B digital apparatus complies with Part 15 of the FCC Rules and meets all requirements
of the Canadian Interference-Causing Equipment Regulations. However, if this control does cause harmful interference to
radio or television reception, which is determined by turning the control off and on, the user is encouraged to try to correct
the interference by re-orientating or relocating the receiving antenna, relocating the receiver with respect to this control,
and/or connecting the control to a different circuit from that to which the receiver is connected.
Cet appareil numérique de la classe B respecte toutes les exigences du Règlement sur le matériel brouilleur du Canada.
