Thermostat
NRG-Temp is intended for flush mounting in a
standard 65 mm wallbox. It should be positioned
approximately 1.5 metres above the floor, protected
from direct sunlight and draughts. All electrical
conduits passing into the thermostat box that contain
cables must also be sealed to protect the thermostat
against draughts, e.g. with a piece of insulation in
the conduit outlet.
NRG-Temp can also be mounted in an external wall
box. If the thermostat will be mounted on a rough
wall surface, e.g. bricks, use silicon glue to make a
seal with the top frame. Assembly frame and front of
thermostat can be removed by pushing with a screw
driver on the two fasteners located on the sides of
the thermostat. (Fig. 2)
Floor sensor
The floor sensor should be installed in a separate
flexible conduit/hose for easy replacement. For best
control performance, position the floor sensor between
two heating cables as close as possible to the top floor
surface. Do not position the floor sensor tip closer than
3 cm to the heating cable.
The floor sensor cable can be extended to 100 m with
a separate standard installation cable 2 x 1.5 mm
(230VAC).
In order to avoid signal disturbance resulting in a
possible malfunctioning of the thermostat, the sensor
should not be installed in a conduit together with other
cables.
