INSTALLED HEATING - DUOHEAT RADIATOR 'CENTRAL' CONTROLS - CONTROL OPTIONS

Mains borne signalling connection

Mains borne signalling (MBS) uses the standard twin and earth wiring in the domestic supply circuit to carry a modulated signal between each heater. A receiver cassette is required in each slave heater to decode the signal. Unique electronic identity codes in each programmer prevent interference with receivers in different zones/buildings and negate the need for additional mains filtering.

This system is ideal for use in existing buildings where it is not possible to install an additional hard wired connection between heaters.

MBS Four Zone Configuration

Note: Heaters and programmers should be installed on the same supply circuit, connected to the same phase. For a 3ph installation a phase coupler should be used.

Pilot wire connection

Pilot wire installations utilise an additional control wire linked between each heater. This is a 240V live conductor, carrying a low current signal to activate the various modes on the heater electronic control. Up to 20 heaters per zone can be supported (dependent on controller).

This system is ideal for new build applications as the pilot wire can be installed with the first fix wiring. As heaters require no additional receivers, this offers a cost-effective means of central control.
