by a competent person or electrician in
conjunction with the current IEE Wiring
Regulations and relevant Building
Regulations
x DO NOT cover or obstruct the air inlet
or air outlet vents

General Principle
The RXMBS4 controller is compatible with Dimplex DuoHeat, EPX, EVS,
RPXN, Calidou and Apollo heaters.
The RXMBS4 controller is designed to allow control of Dimplex heaters from a
single point. Mains Borne Signalling uses standard live, neutral and earth
wiring to carry a signal to each heater. Each heater requires a receiver cassette
(Part no. RX9913 or part no. RX03002 for DuoHeat radiators) to receive the
signal from the RXMBS4 controller and change the heater mode. (e.g. comfort,
background or on, off)
