INSTALLING THE SENSOR (FIG. 2)  
• Insert the sensor cable 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 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 is undamaged on both the  
electrical wiring and the floor sensor. Never use two spare wires  
in a multi-core cable.  
PLACEMENT OF THE THERMOSTAT (FIG. 3)  
The thermostat should be mounted on the wall approx. 1.5 m  
above the floor in such a way as to allow free air circulation  
around it. Draughts and direct sunlight or other heat sources  
must be avoided.  
OPENING THE THERMOSTAT (FIG. 4)  
1. Switch off the thermostat  
2. Insert a small screwdriver in the bottom right slot of the  
thermostat.  
3. Turn the handle of the screwdriver outwards while gently pulling  
the right side of the bottom a few millimetres towards you.  
4. Insert the small screwdriver into the bottom left of the  
thermostat.
