Use the boiler/burner manufacturers wiring diagrams to determine the connections to the NXM2G
as in
Figure 1.
•
Wire the connector as in
Figure 1.
•
Plug the connector into NXM2G as in
Figure 1.
•
The supply (flow) and supply return temperature sensors need to be fixed to the correct boiler pipe
work connections; this should be as close to the boiler as possible. This may require the pipe work
insulation to be removed. Using appropriate banding (clamp), secure the sensors to the pipe.
Please note: Do not over tighten, as this may damage the sensor.
Replace the pipe work insulation on completion. Plug the correct supply (flow) and return sensors
into the NXM2G terminal as detailed in
Figure 1.
•
Ensure that all connections, including ground/earth connections, are secure. Replace covers with
screws provided.
WARNING:
Ensure that the NXM2G mains electrical supply is on the same phase
/ burner’s electrical supply.
as the boiler
