In your scenario you would need 2 zones and 2 t stats.
Schluter floor temperature sensor.
Do not place furniture or mats over the floor temperature sensor as they could act as insulation and lower the temperature of the floor warming system therefore causing the floor to feel cooler.
It may be necessary to temporarily secure the splice to the floor with thin set mortar or adhesive hot glue.
Floor temperature sensors may not be threaded through the same conduit as the cold lead.
The floor temperature sensor should not be installed inside the shower area rather on the bathroom floor.
Reinstall the front part of the thermostat on the mounting base.
Both floor temperature sensors are installed within the tile assembly.
Test 4 temperature sensor.
Then connect the wires of the floor temperature sensor at the indicated location behind the thermostat.
Let s dive into the tests one by one.
Two sensors are supplied incase one fails in the future you pull the t sat and connect the spare sensor after disconnecting the failed sensor.
Test the floor temperature sensors using a multimeter to verify accuracy of the sensors.
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.
Mark where the cold hot splice will be placed cut the ditra heat or ditra heat duo matting and insert the splice.
Although schluter will extend the warranty from 10 years to 15 years if you do the insulation resistance test.
An insulation resistance test is recommended but not required.
Floor warming into service.
If you have set the t stat to read ambient it ignores the floor sensor and adjust the floor using the rooms air temp.
Schluter ditra heat e rt ditra heat e rt is programmable touchscreen thermostat that allows you control your electric floor warming system any way you want.
Set the multimeter for resistance at 10k ω 2 at room temperature and take a reading between the sensor leads.
The second sensor can be connected in case of damage to the first sensor without.
One sensor is connected to the thermostat while the other is stored in the thermostat electrical box.
The resistance will vary according to the temperature i e the colder the sensor the higher the resistance.
Floor temperature sensor test.
One 1 floor sensor.
After the curb is installed schluter kerdi waterproofing membrane is installed over the ditra heat system on the shower base and all other waterproofing steps must be completed.
The thermostat features a 5 ma built in ground fault circuit interrupter gfci with indicator light and includes a floor temperature sensor.
Why are two floor temperature sensors provided with the schluter ditra heat system.
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.
