The floor sensor should be installed within an approved non conductive installation pipe in accordance with EN 61386-1, which is embedded
in the floor. The pipe (flexible conduit) should be placed as high as possible in the subfloor. The floor sensor should be located equidistant
between two runs of the heating element with the tip at least 300mm away from the outside edge of the heater.
The enclosed 3 meter sensor cable can be extended up to 50m by means of a separate cable. The installation pipe must not contain any other
cables, such as the supplies to the heating wire. The switching peaks of such current supply lines may create interfering signals that prevent
optimum thermostat function. The heating supply cable should be placed in a separate pipe.
In the event of sensor failure, replacement of the sensor can be carried out with ease providing the sensor is installed within flexible conduit.
The floor sensor should never cross the heating element.

Remove this sensor from circuit before performing any high voltage insulation tests.
IMPORTAT:
ALWAYS DISCONNECT THE MAINS SUPPLY VIA THE SWITCH IN THE MAIN FUSE BOARD, CONSUMER UNIT BEFORE
COMMENCING ANY ELECTRICAL WORK. WHEN CONNECTING CABLES TO THE THERMOSTAT, ENSURE THAT ALL TERMINAL
SCREWS ARE FULLY TIGHTENED AND THAT EARTH WIRES ARE SLEEVED AND THAT NO BARE WIRES ARE SHOWING.
Release the front of the thermostat by
inserting a small flat screwdriver into
the 2 slots on the base.
Make electrical connections as de-
tailed in previous section.
Electrical connections are to be made as detailed on diagram. The circuit supplying this controller must be protected by a 30mA RCD. All
electrical connections must be performed by a fully qualified and part P certified electrician. Any doubts surrounding the installation of this
controller should be passed to the distributer prior to installation. Testing of all under-floor heating systems should take place prior to floor
coverings being installed..
Mount base part of thermostat onto
either a BS recessed or surface
mounted box.
