3. Mounting and installation<br />
<strong>Thermostat</strong><br />
TA is intended for flush mounting in a standard 65 mm<br />
wallbox. It should be positioned approximately 1,5 metres<br />
above the floor, protected from direct sunlight and<br />
draughts. All electrical conduits passing into the thermostat<br />
box that contain cables must be sealed to protect the<br />
thermostat against warm air, e.g. with a piece of insulation<br />
in the conduit outlet.<br />
TA can also be mounted in an external wall box. If the<br />
thermostat will be mounted on a rough wall surface, e.g.<br />
bricks, put a string of silicon glue under the top frame.<br />
Assembly frame and front can be exchanged by pushing<br />
with a screw driver on two knobs, placed on the sides of the<br />
thermostat. (Fig. 2)<br />
Floor sensor<br />
The floor sensor should be installed in a separate flexible<br />
conduit/hose for easy replacement. For best control<br />
performance, position the floor sensor between two heating<br />
cables as close as possible to the top floor surface. Do not<br />
position the floor sensor tip closer than 3 cm to the heating<br />
cable.<br />
The floor sensor cable can be extended to 100 m with a<br />
separate standard installation cable 2 x 1.5 mm2 (230VAC).<br />
In order to avoid signal disturbance resulting in a possible<br />
malfunctioning of the thermostat, the sensor should not be<br />
installed in a conduit together with other power carrying<br />
cables.<br />
Connection of the thermostat<br />
The thermostat must be connected to 230VAC according to<br />
the circuit diagrams. When connecting multiple heaters to<br />
the thermostat where the combined total load is above 13A,<br />
you are required to use a contactor or switchgear.<br />
If the protective earth terminal, (PE) on the thermostat is<br />
used, the incoming power cable to the heating cable shall be<br />
connected to the common earth terminal on the thermostat,<br />
otherwise a separate terminal connection block (not<br />
included) must be used.<br />
