11/14/2023 0 Comments Ditra electric radiant floor heatingAdditional DITRA-HEAT-E-RT thermostats must be used or the DITRA-HEAT-E-RT thermostat may be combined with the DITRA-HEAT-E-RR power modules. Multiple DITRA-HEAT-E-HK heating cables over 15 amps cannot be connected to a single DITRA-HEAT-E-RT thermostat. The heating cable leads must be wired in parallel according to applicable electrical and building codes. Note: Two DITRA-HEAT-E-HK heating cables can be connected and controlled by a single DITRA-HEAT-E-RT thermostat if the total current is less than 15 amps. Replace the thermostat faceplate and tighten the screw at the bottom of the unit. The power, heating cable, and floor temperature sensor connections are now complete. Tighten the screws to secure the wires.ġ3. Note that the floor temperature sensor wires have no polarity and can be interchanged between C and D terminals. Insert the floor temperature sensor wires into terminals C and D. Strip the ends of the floor temperature sensor to expose the wires for ease of installation. Tape up the secondary floor temperature sensor and secure to the power base.ġ2. Thread the floor temperature sensors through the opening at the bottom right of the thermostat power base. Align and secure the thermostat power base to the electrical box.ġ1. Secure the wires by tightening the screws and fold the wires into the electrical box.ġ0. Refer to the back of thermostat for proper wiring configuration.ĩ. Insert the electrical line wires into the line terminals from the top. Secure the conductors by tightening the screws.Ĩ. Since there is no polarity, either heating cable conductor can be connected to either load terminal.ħ. Insert the heating cable conductors into the load terminals from the bottom. ![]() Loosen the load screws at the top of the thermostat until they stop.Ħ. This will make it easier to fold them neatly into the electrical box. Once the cable is installed it’s testedmore than onceto ensure there are no cuts before the tile goes down. CeraZorb® is a synthetic insulating underlayment that has a higher degree of thermal resistance (R-value of 1.5) than cork. The heating cable snaps into the space between studs on the Ditra-Heat-Duo membrane. Rolling the Ditra helps ensure good adhesion. For ease of installation, form the electrical line wires into an “M” or accordion shape. The bottom of the membrane has a fleece fabric that’s adhered to the subfloor with thinset. Remove the faceplate from the thermostat power base by loosening the screw and tilting the thermostat upward. Connect the heating cable ground braid to the ground wire from the electrical panel.Ĥ. ![]() ![]() The power supply must be shut off and all electrical connections must be made by a qualified electrician, according to the electrical and building codes effective in your region.ģ. A single gang, deep electrical box or a double gang electrical box with a single gang mud ring is recommended to provide room for the wiring.Ģ. DITRA-HEAT-E-RT must be installed in an electrical box. Please refer to the Interactive User Guide and Schluter®-DITRA-HEAT Installation Handbook for complete DITRA-HEAT system installation instructions.ġ.
