TOUCHSCREEN PROGRAMMABLE THERMOSTAT - The DHERT102/BW Ditra Heat thermostat is designed to control radiant floor heating cables. This thermostat has six programming periods per day, a set-up wizard and an energy log. It has a built-in 5 mA ground fault circuit interrupter (GFCI) and works with 120-Volt and 240-Volt cables.

142.9 SQ FT DITRA HEAT MEMBRANE - polypropylene membrane with a cutback stud structure and an anchoring fleece laminated to the underside. The membrane is designed to secure the DITRA-HEAT-E-HK electric floor heating cables and provide uncoupling, waterproofing, vapor management and support to ensure a long lasting installation.

THERMAL PACK - Eliminates cold spots between wire meaning that thermal heat diffusion is increased by 20% while reducing energy costs by 15% since heat is transferred faster and more uniformly. (5x Bags) of thermal pack are included in the kit. Thermal Pack must be used with grey color modified mortars (thinset).

SAFETY: Includes either Nuheat MatSense Pro OR SunTouch Loudmouth monitor electric fault indicator. This device sounds an alarm if the heating wire is cut or damaged, identifying a problem with the installation before the heat wire is tiled over. Suntouch plastic 3/8" x 1/2" U-notch cable trowel is designed specifically for heat cables installation and eliminates the risk of damaging the heating cable while applying mortar.
