Heater wiring schematic diagram with relays
When more heating units need to be connected from the same controller a relay will be required. It is recommended that
you talk to your electrician for more detail.
Below is an example circuit indicating one potential installation configuration.
Always check with your electrician and ensure all wiring is in accordance with local regulations.
Note to electrician: The controller modulates the heat output using a “timed on / timed off” function. The controller does
not modulate the voltage output. A relay is therefore suitable for this application.
