INSTALLATION: KEY POINTS

• Before laying the mat the ﬂ oor sensor (in controller box) MUST be installed. The

sensor is ﬁ tted into a tube (in mat box) which should be laid 20-30cm across the ﬂ oor under the mat between a cable loop.

• Before laying check the continuity of the cable, it should match the Ohm rating

™

on the Devimat

label with a tolerance of -5 to +10% and check the insulation

resistance which should read inﬁ nity.

• To install the mat simply cut and turn the mat. The heating cable must NOT be cut or subjected to strain around the area of the coupling, only the blue and black cables can be cut to suit.

• When installing more than one mat, all ‘cold tails’ (blue/black wires) must be taken back to the connection point/controller, DO NOT wire one mat to another.

• After laying the adhesive the heating mat must be checked once again for continuity and insulation resistance, then connected by an authorised electrician.

• The blue central core is NEUTRAL and the black central core is LIVE. The outer

surrounding copper wire is the earth screen and should be connected to earth.

product.

• Installation on new concrete ﬂ oors should not be carried out for approxi-

mately 30 days to ensure thorough drying out.

Installing the Devimat

1. Draw up a plan of the room and calculate the free ﬂ oor area. Use the plan to work out how to lay the mat evenly across the ﬂ oor and show the location of the cold tail (where the mat starts), ﬂ oor sensor and connection box. The Devimat obstructions and close ﬂ oor ﬁ tting objects like pipes, baths and cupboards. It is acceptable to lay the devimat under suspended cupboards and wash basins.

2. Mark the positions of the ﬂ oor ﬁ tting objects that will be installed once the ﬂ oor is ﬁ nished, so when laying the mat these can be avoided.

3. Each mat is supplied with a piece of 10mm ﬂ exible tubing (only one tube is required for each thermostat), this is for the ﬂ oor sensor, so that in the unlikely event that the sensor fails, it can be

4. The existing ﬂ oor should be prepared as normally required for tiling, this may include cleaning and removing all loose particles, removing any sharp protrusions that may cause damage to the heating wire, priming the ﬂ oor surface and bracing a timber ﬂ oor with WBP ply-for professional guidance refer to your adhesive

manufacturers recommendations.

easily removed and replaced without lifting the ﬂ oor. In some situations a small channel may have to be made in the ﬂ oor to accommodate the tubing. If so, cut a channel from the thermostat position approximately 20-30cm across the ﬂ oor.

It is important that the

channel is positioned such that it lays between two heating wires and not across them and not above heating pipes below the ﬂ oor. The

end of the tubing in the ﬂ oor is sealed with tape to prevent

adhesive entering the tube.

5. Before laying the mat should be tested-see page 7.

Remove the plastic outer and place the cold tail of the mat at the connection point. The Devimat™ has a self-adhesive backing, lay this to the ﬂ oor and roll the mat out, if necessary the mat can be laid with the cable face down. In situations where the mat has to be turned over it can be secured using Devipins, hot glue gun (taking care not to damage the heating cable), staple gun or double sided tape.

™

6. When the Devimat

reaches the end of the run, simply cut the grey mesh (NOT THE RED CABLE) and turn the mat, positioning the next piece beside the ﬁ rst. When cutting and turning the mat ensure there is a 50mm gap between the cable loops. To avoid risk of damage at later stage do not lay the mat where objects will be put onto or ﬁ xed to the ﬂ oor.

7. If required, the cable can be removed from

the mesh and loops formed manually, but ensure the cables are spaced the same distance as those on the mat.

• The devimat™ must NOT be installed across two or more rooms

• The heating cables (RED CABLE) must not touch or cross each other.

• The heating cables (RED CABLE) must not be CUT.

• All the red heating cable must be within the ﬂ oor.

8. The mat should be tested-see page 7. The mat can now be covered in one of two methods Concrete and wooden ﬂ oors using ﬂ exible tile adhesives Working with a width of devimat at a time, apply ﬂ exible tile adhesive through the mat with a rubber back trowel or similar so that the heating cable is covered, making sure that there are no air pockets. Another layer of adhesive can then be applied carefully using a suitable notched trowel to comb the adhesive before applying the tiles. Concrete and wooden ﬂ oors using self-levelling compounds An alternative method is to cover the devimat with a suitable self levelling/ latex type compound. This product will ﬁ nd its own level giving you a ﬂ at surface to then apply a layer of ﬂ exible tile adhesive using a suitable notched trowel to comb the adhesive before applying the tiles. The mat should be tested-see page 7.

Flooring note:

Whichever ﬂ oor covering is being used with the Devimat system, it must be covered with a latex/adhesive covering before the ﬂ oor ﬁ nish is laid, the suitability of which should be checked for use with underﬂ oor heating with the manufacturer. If using Devimat beneath wood laminate ﬂ ooring, you must only use the thin foam type sound-deadening layer, this must not exceed 3mm.

Wiring and controlling the devimat

A qualiﬁ ed electrician must connect the heating mat, in accordance with the current wiring regulations BS 7671. It is recommended that the Devimat™ be connected via a 30mA RCD (residual current device). Wiring regulations state that the thermostat should be located away from sources of water, i.e. outside the bathroom. As the thermostat is sensing ﬂ oor temperature, the control unit can be located at any level from the ﬂ oor. ONLY the cold tail(s) of the Devimat™ and the black ﬂ oor sensor should be leading from the ﬂ oor to the thermostat position. The Devimat™ must be controller using either a Devireg™ 130 or a Devireg™ 550, both of which use a ﬂ oor sensor to monitor the ﬂ oor temperature. Both thermostats have a switching limit of 16 amps (35m2 of Devimat™ on timber ﬂ oors or 23m2 of Devimat™ on concrete ﬂ oors) if above these limits a contactor or multiple controllers should be used.

Wiring the Devireg™ 130-see instructions enclosed with the Devireg™ 130. Wiring the Devireg™ 550-see the instructions below:

Wiring The Devireg™ 550 The sensor cable, heating mat and electricity supply can now be connected. Five simple steps to connecting your controller are:

1. The mains voltage is connected to the terminals marked (Mains L & N). L = Live N = Neutral

2. The devimat™ is connected via terminals L and N where : Blue Cable Central Core = Neutral Black Cable Central Core = Live

3. The screening around the black and blue wires of the devimat™ should be connected to the earth terminal within the electrical box, in accordance with the electricity regulations.

4. The sensor must be connected to the terminals marked NTC. This cable can be shortened as required and connected either way round.

5. The ‘Network’ terminal is not used.

Installation complete

Following installation the Warranty Certiﬁ cate on the back of this user guide should be ﬁ lled in.

The Devimat™ system should not be turned on until the adhesive and tile grout has completely dried, then once dried it can be turned on gradually over a 48 hour period.

No close ﬁ tting objects should be laid or ﬁ xed to the warm ﬂ oor area, for example thick mats or beanbags.

Testing

At each stage of the installation it is recommended that the heating mat is tested for the following:

Continuity- This checks that the heating cable (blue and black wires) are intact and have the correct resistance. The resistance is checked with a multimeter and the reading should match the resistance rating on the label on the cold tail of the Devimat™ with a tolerance of -5 to +10%. Ensure your multimeter is capable of reading values between 28-550 ohms.

Insulation- This checks that the earth screen around the heating cable has not been damaged and shorted to the heating cables. The test can be made with a multimeter and can be done by testing the path between the blue cable and the earth screen and the black cable and the earth screen, both should read inﬁ nity.
