Features

LH-Kit is an alternative to LH Heating Films and is Ideal for use when the floor area is known but the layout of the room cannot be verified.  The installer will be required to cut the film to length and to make crimped connections using the tool provided.  This system should only be installed by a professional electrician.

Film Specification

• Approved to EN60335-2-96 as required by the 17th Edition Wiring Regulations (BS7671.2008)
• EMC compliant
• 230V supply
• Polyester film less than 1mm thick

Installation

Three layers are required:

1st Layer - DEP6 Insulation/Underlay

The entire floor area must be covered by a 6mm thick layer of DEP6. This layer performs four functions.

• Thermal insulation limiting downward heat loss
• A moisture proof barrier between the heating film and the sub-floor
• Sound deadening
• A non-abrasive surface onto which the heating film can be installed

2nd Layer - LH-K Film

A number of LH-K heating films are installed side by side to fill the floor area

The heating films are electrically connected in parallel and controlled by a single thermostat

3rd Layer - VB Vapour Barrier

The entire floor must be covered in a layer of VB vapour barrier. This layer performs three functions

• Secondary electrical insulation
• Protection from major liquid spills
• A mechanical barrier between the heating film and the floor surface preventing abrasion DEP6, LH Film and VB should all be secured using LHT High Adhesive Tape. One 50m roll is required for each 10m² of floor area.

Control

Thermostatic control must be used. BN Thermic offers a range of thermostats all of which are supplied with a floor probe. The thermostats can be configured for primary control via the built-in air sensor or via the floor sensor. For larger rooms, check that the combined load of the heating films is within the switching capacity of the selected thermostat. When the combined load is greater than the switching capacity of the selected thermostat an appropriately rated contactor must be selected.

A16C

Simplicity is the key. The A16C has a smart uncluttered appearance with a dial for temperature adjustment and an on/off switch. Capable of switching loads up to 3.4kW, the A16C is configurable for ‘air and floor sensor’ or ‘floor sensor only’

U16C

The U16C offers simple 7-day programming with programming buttons hidden behind hinged doors on the thermostat face. Capable of switching loads up to 3.4kW, the U16C is configurable for ‘air and floor sensor’ or ‘floor sensor only’. Features include a backlit screen and a summer switch allowing the heating to be switched off without losing the programme.

T16C

Our latest full colour touch screen thermostats can switch loads of up to 3.6kW and provide ultra-simple 7-day programming.  Available with a choice of white or silver surrounds, the T16C can be configured for ‘air and floor’ or ‘floor only’ control.  When required, the air temperature can be controlled via an IP65 rated remote mounted wall-sensor (T16R).  This arrangement is particularly well suited for bathroom applications. The T16C also allows the user to monitor energy usage and running costs.
