Rough-In Wiring

Line Voltage Wiring

In most cases, the control can be mounted directly to a wall
without the need for any line voltage connections.

As an option, the control may be mounted to a 4” x 4”
electrical junction box so that the high voltage electrical
connections for the transformer are safely contained.

For ease of service, the circuit breaker or power disconnect
should be located in reasonably close proximity to the
equipment.

All line voltage wire connections are recommended to
be pulled inside a flexible or solid conduit. Always follow
proper wiring practices, building and electrical codes for
your jurisdiction.

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

Each cable must be pulled to the electrical junction box. It
is recommended to label each cable for easy identification.
All line voltage wires should be stripped to a length of 1/2”
(13 mm).

Pull a three conductor 14 AWG cable for the following
equipment:

Circuit Breaker or Power Disconnect (if applicable)

Low Voltage Wiring

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

Each cable must be pulled from the equipment to the
control’s plastic enclosure. All low voltage wiring connections
enter the enclosure through conduit knockouts on the
sides, or through the square knockouts on the rear. It is
recommended to label each cable for easy identification.
All low voltage wires are to be stripped to a length of 3/8”
(9 mm) to ensure proper connection to the control.

The control requires an external transformer. A tekmar
Transformer 009 (or 009K which includes a 4”x 4” electrical
box) can supply up to 40 VA, and includes an in-line fuse
to protect the transformer and control.

In order to correctly size the external transformer, all loads
connected to the control must be taken into account.

When adding up the loads, consider the following:

Thermostats 527, 528, 529, and 530 draw approximately

•

1.3 VA each.
Each zone valve must be sized for peak load. This can be

•
obtained by multiplying the peak current draw (in Amps)
by 24 V (ac).

Two-Stage tekmarNet®2 Thermostat Wiring

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

A two stage thermostat is automatically detected when
connected to Zone 1 or Zone 3. If there is no tN2 thermostat
connected to Zone 2 or Zone 4, these outputs will automatically
operate the heating equipment for second stage heat.

Stage 1 Stage 2 Stage 1 Stage 2

Testing the Power

If the control Power light does not turn on, check the Input
Power wiring terminals using an electrical multimeter. The
voltage should measure between 21.6 to 26.4 V (ac). If the
voltage is below this range, measure the line voltage side
of the transformer. The voltage should measure between

103.5 to 126.5 V (ac).

Testing the Thermostats

If the thermostat display turns on, this indicates that the
thermostat is operating correctly and there are no electrical
issues. In the event that the display is off, or the display is
cycling on and off, follow this procedure.

1. Remove the tN2 wires from the thermostat.

2. Use an electrical meter to measure DC voltage between
the tN2 terminals.

If the DC voltage is 0 V (dc) for 20 seconds, then there is
an open or short circuit in the tN2 wires. If the DC voltage
is 0 V (dc) for 10 seconds and then is 23 to 24 V (dc) for 5
seconds, this indicates the wiring is correct.

3. Connect the thermostat to the tN2 wires from a zone
on a House Control, Wiring Center, or Zone Manager.

4. If the thermostat display is off, or is cycling on and off,
move the thermostat to the next available zone on the
House Control, Wiring Center, or Zone Manager.

If the thermostat display remains permanently on, there
may be a fault with the previously tried zone on the House
Control, Wiring Center, or Zone Manager.

If the thermostat display continues to be off, or is cycling
on and off, there may be a fault on the thermostat.
If a fault is suspected, contact your tekmar sales representative
for assistance.

Testing the Zone Output

1. Use an electrical test meter to measure the (ac) voltage
between the C and the Vlv terminals for each zone valve
output.

Lower the thermostat temperature setting. When the

•

zone LED is off, the reading should be 0 V (ac) and the
valve should be closed.

Raise the thermostat temperature setting. When the

•

zone LED is on, the reading should be 24 V (ac) + / –
10% and the valve should be open.

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

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

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

Note: If power to the zone valve is present but the zone
valve does not operate properly, refer to any troubleshooting
information supplied by the zone valve manufacturer.

Testing tekmarNet®4 Expansion

To test the tN4 Network, check the wires for continuity
and shorts.

1. Disconnect the two tN4 expansion wires (tN4 and C) at
one end and twist them together.

2. Go to the other end of the wires and disconnect
them.

3. Using an electrical test meter, check for continuity.
Resistance should read 0 ohms, or continuity should
produce a tone. If not, this indicates that there are
damaged wires connecting the tN4 control to the 313.
Repair or replace the wires as necessary.

4. Go back to the original end of the wires and, using a
wire nut, cap each expansion wire individually so that
these ends cannot touch another conductor.

5. Go to the other end of the wires and again, test for
shorts. Resistance should be infinite, or O.L. and there
should be no tone. If tone exists or less than 50 000
ohms is found, then the wires are not insulated from
one another. This is generating a short on the wires
connecting the tN4 control to the 313.

6. Replace the damaged wires, test, and reconnect them
to their proper terminals.

Testing The End Switch / Zone Group Pump

If the tN4 expansion terminals are not used to connect the
313 to the system, the end switch may be used.

1. Remove the wires from the end switch terminals.

2. Use an electrical test meter to measure continuity across
the XX end switch terminals on the 313.

When the end switch LED is off, no continuity should

•

be present (no tone).
When the end switch LED is on, continuity should be

•

present (tone).

3. Use an electrical test meter to measure voltage across
the zone group pump hot switch leg and neutral.

When the end switch LED is off, the voltage should be

•

0 V (ac).
When the end switch LED is on, the voltage should be

•

between 103.5 to 126.5 V (ac).

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

DIP Switches

Each zone has a corresponding zone group pump DIP
switch. Set the switch to On to operate the zone group pump
output whenever that zone calls for heat. When the DIP
switch is set to off, the zone group pump will not operate
when that zone calls for heat.

Sequence of Operation

tekmarNet® System

tekmarNet® is a family of products that use communication
to operate the HVAC system in a comfortable and efficient
manner. The Wiring Center is a zoning component in
a tekmarNet® system and requires tekmarNet®2 (tN2)
Thermostats to be directly connected to it.

The tekmarNet®4 (tN4) Expansion terminals can link the
Wiring Center with other tekmarNet® components:

Relay Outputs

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

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

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

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

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

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

Section B

End Switch Operation

The End Switch relay (‘XX’) closes and the end switch
LED turns on. The switch remains closed as long as any
zone is calling for heat. This can provide a boiler demand
to a tekmar reset control, or provide a boiler enable to a
boiler’s TT terminals.

If the Wiring Center is connected to a tN4 bus, all
communication messages will pass through the 313’s tN4
expansion connection. tN4 messages are required in order
to create a boiler demand on a device such as a tekmar
House Control 400.

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

Energy Saving Features

Network Schedules

Adding a schedule to a tekmarNet® system is both easy
and valuable. A Timer 033 provides scheduling with up to
4 events per day for every tekmarNet® Thermostat. Turning
down the room temperatures when they are unoccupied
reduces boiler on-time and energy consumption which
helps save money and the environment.

One-Touch Economy

A User Switch 479 allows for one-touch overrides of the
system. For example, if leaving the building for vacation,
simply press the “Away” button and all the thermostats
will immediately operate at a lower temperature, instead
of having to walk around the building lowering the heating
temperature setting and raising the cooling temperature
setting on each thermostat.

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

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

24 V (ac) Zone Relay Operation

When a thermostat calls for heat, it sends a message to
the Wiring Center and the corresponding zone LED turns
on. Power is then supplied to the appropriate zone output
as indicated by the LED.

Zone Group Pump Operation

The zone group pump remains on when any zone is calling
for heat and the corresponding DIP switch is set to ON.
When using thermal actuated zone valves, a 3 minute time
delay can be set on the thermostat to allow the zone valve
to fully open before the zone group pump is activated.

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

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

Section C

Zone Synchronization

The Wiring Center includes an energy saving feature
called Zone Synchronization. In typical zoned systems, the
thermostats operate on a stand-alone basis. This means
that a zone turns on and off as required without any regard
for other zones. The net effect is random operation of the
zones causing short cycling of the heat source. tekmarNet®
thermostats communicate to ensure that their cycles are
synchronized. Energy is saved by ensuring zones requiring
heat operate on the same cycle, therefore reducing short
cycling of the boiler.

During AWAY, the thermostats operate at a lower temperature. Locate a ‘User
Switch’ and set to Normal to resume heating.

Thermostats have a differential of +/- 1.5°F (0.8°C) of the temperature setting.
Due to the display rounding numbers up, heating can appear on when the
temperature is 2°F (1°C) above the setting. This is normal operation.

Ensure zone valve terminals measure 0 V (ac). Measuring 0 V (ac) indicates
mechanical zone valve may have failed in the open position. Measuring 24 V
(ac) indicates control relay may have failed.

Ensure zone valve terminals measure 24 V (ac). Measuring 24 V (ac) indicates
mechanical zone valve may have failed in the closed position. Measuring 0 V
(ac) indicates control relay may have failed.

The zone has an open or short circuit and communication to the thermostat on
the zone has been interrupted. Check the wiring between the thermostat and
the Wiring Center for open or short circuits. If the thermostat was intentionally
removed, power the Wiring Center off for 10 seconds.

defective product, and such repair, exchange or credit shall be the sole
remedy available from tekmar, and, without limiting the foregoing in any
way, tekmar is not responsible, in contract, tort or strict product liabil­ity, for any other losses, costs, expenses, inconveniences, or damages,
