MTD3 Instructions
4. INSTALLING THE SENSOR
• Insert the cable and sensor into a non-conductive conduit embedded in
the floor.
• The end of the conduit must be sealed and the conduit placed as high as
possible in the concrete layer.
• The floor sensor must be centred between loops of heating cable.
• The sensor cable may be extended with additional two-core cable (max.
sensor extension, see Technical Specifications).
• The two wires from the sensor to the thermostat must be kept separate
from high-voltage wires/cables. Place the sensor cable in a separate
conduit or segregate it from power cables in some other way. Ensure that
the insulation on both electrical wiring and floor sensor inside the junction
box are not damaged. Never use two vacant wires in a multi-core cable.
