It is highly recommended that you use the conduit supplied for the sensor so that in the event that the sensor should need to be replaced; it can be achieved without disturbing the floor.

The location of the thermostat is your choice but it makes sense to locate it as near to the electricity supply as possible and is normally in the room being heated. Note for wet areas (e.g. bathroom) it must be outside of the room.

Connect via a fused spur or use a dedicated supply with its own RCD (consult your electrician). The thermostat sensor must be positioned between cable loops so measure where this will be and cut a channel approximately 10mm x 10mm deep and 300mm long in the insulation to locate the flexible floor probe conduit in.

The thermostat is rated at 16amps and will control a maximum heated area of 3680 watts.

Testing

It is highly recommended that you connect your system via a fused spur (to isolate the system for future maintenance) and/or a safety contact breaker (RCD); an electrician will be able to advise you.

T he electrician should affix a suitable advisory warning notice on the electricity distribution box and complete the attached certificate which must be retained to serve as part of the guarantee requirement.

Switching on

Before switching on the underfloor heating allow a minimum of 3 days for natural drying of the tile adhesive and grout. It is recommended that you gradually increase the operating time of the system over the first week from 1 hour, increasing by a further 1 hour per day to full continuous use.
