A correctly controlled domestic central heating system provides a better comfort level, uses less energy and produces lower CO2 emissions. ChannelPlus is a premier range of advanced, electronic heating and hot water programmers that offer up to four independent channels and feature improved displays and easier programming. Use of the three and four channel models facilitate “zoning” of heating systems offering even greater levels of control and energy savings in larger properties.
