The Bromic Heating Wireless Controller has the ability to switch power supply to two separate outputs, enabling independent 'On/Off' control of two single-element heaters (2kW or 3kW), a single twin-element heater (4kw or 6kW) per unit, two gas heaters of your choice or up to four gas heaters controlled in groups of two. The unit's 4-channel remote control transmitter is entirely portable but can be easily mounted with a double sided adhesive or with screw provisions within the case. *All Bromic Heating remotes are able to control an infinite number of heaters within a 30m range.
