Quick Start Installation Guide

The Thermostat and Relay Box in this are pre-bound.
Must be installed by a competent person. To ensure your safety make sure the mains power is switched OFF before accessing wiring.

To prevent a short circuit from a loose wire:

  • Multi-core cables: Only remove enough outer insulation to allow secure fixing of the cores into the terminal block.
  • Single core cables: Secure them together with a cable tie as close as possible to the terminal block.

Install the Relay Box


  • On/off boiler (230V)
  • Combi boiler
  • 2-Port Zone Valve

Install the Thermostat
