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

To prevent the risk of personal injury and/or death, make sure power is not applied to the thermostat until it is fully installed and ready for final testing. All work must be done with power turned off to the circuit being worked on.

Please be aware local codes may require this thermostat to be installed or connected by an electrician.

Mounting The Thermostat Base

If a single gang box is used:

Feed the wiring through the large

• hole of the thermostat base.

Fasten the base of the thermostat

• to the gang box.

Terminate wiring to the wiring

• strip.

Push the thermostat front onto

• the thermostat base.

Thermostat Wiring

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

The thermostat operates a single heating system zone and can be wired in four different ways.

tekmarNet®2 - Allows the thermostat to be wired point-to-point using 2 wires to a tekmarNet®2 Wiring Center, House Control, or Zone Manager. This allows easy wiring for retrofit applications.

tekmarNet®4 - Allows the thermostat to be wired using 4 wires to a tekmarNet Wiring Center or Zone Manager point-to-point. Alternatively, the thermostat can operate heating equipment locally and the tN4 communication bus can be daisy-chained from one thermostat to another.

Stand Alone Stand Alone - Simple 3 wire connection to a switching relay or zone valve control.

- Simple 3 wire connection to a 24 V (ac) transformer and zone valve.

Only qualified personnel should perform testing procedures. A licensed electrician is recommended.

Testing the Thermostat Wiring

Testing tekmarNet®2 Wiring

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

Testing the Power

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:

1. Remove the thermostat front.

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

•

If the DC voltage is 0 V (dc) for at least 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 connected to 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 Heat Zone Output Wiring

1. Touch the button and set the heating temperature above the current room temperature. Make sure the display does not show “WWSD” or “Floor Max”.

2. When the “Heat On” symbol appears on the display, use an electrical meter to check for voltage on the House Control, Wiring Center, or Zone Manager relay. The voltage is 24 V (ac) for zone valves, and 120 V (ac) for zone pumps when operating correctly.

Testing tekmarNet

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

4 and Stand Alone Wiring

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

Testing the Power

1. Remove the front cover from the thermostat.

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.

Testing the Heat Relay

1. Remove the front cover from the thermostat.

2. Touch the button and set the heating temperature below the current room temperature. There should be no “Heat On” symbol on the display.

3. Set the electrical test meter to continuity.

4. Place electrical meter probes between R and W. There should be no continuity. If there is continuity then there may be a wiring fault or the relay may be faulty.

5. Touch the button and set the heating temperature above the current room temperature. Make sure the display does not show “WWSD”. The “Heat On” symbol should appear on the display.

6. There should now be continuity between the R and W terminals.

Testing the tekmarNet

4 Bus Wiring

The symbol is shown on the display when communication is present. If the thermostat 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. To test for short circuits:

•

Disconnect the tN4 bus wires on one end.

•

Install wire nuts on each wire to ensure the wire ends are not touching.

•

Disconnect the tN4 bus wires on the other end.

•

Measure for continuity using an electrical meter.

•

If continuity is present, there is a short circuit fault along the wires. It is recommended to replace the tN4 bus wires.

3. To test for open circuits:

•

Disconnect the tN4 bus wires on one end and connect them together.

•

Disconnect the tN4 bus wires on the other end.

•

Use an electrical meter to measure for continuity.

•

If there is no continuity, there is an open circuit fault along the wires. It is recommended to replace the tN4 bus wires.
