Schluter®-DITRA-HEAT-E-RR is a power module that extends power output when used in conjunction with the DITRA-HEAT-E-RT or DITRA-HEAT-E-R thermostats.

DITRA-HEAT-E-RT is a programmable touchscreen thermostat used to control the DITRA-HEAT-E-HK heating cables (either 120 V or 240 V). The thermostat features a 5 mA built-in ground fault circuit interrupter (GFCI) with indicator light and includes a floor temperature sensor. DITRA-HEAT-E-RT is operated via LCD touchscreen controls and features a pre-set schedule for convenience, which may be programmed to fit any schedule. Two heating cables may be connected to the thermostat, up to the total heating load limit of 15 amps.
