SunTouch. Designed for large floor heating needs exceeding 15 amps, the GroupStat control divides the application into zones with individual units. Because a master thermostat, available in programmable and non-programmable versions, links and controls up to 10 slave units, the units can be installed anywhere, the maker says. The slave units are offered in 120 or 240 volts. 888.432.8932. www.suntouch.net.
