Mode, by pressing the button you can toggle between
these two modes.

Manual Mode

In this mode the temperature set on the
display is maintained 24 hours a day,
i.e. no timing facility and therefore no
displayed. Whilst in manual mode, if you
rotate the dial to level 1.0 then turn the
dial vigorously further anti-clockwise,
the thermostat will switch o and display
‘OFF’.

Enter timer mode

end of the period and press button again.
Continue this through the whole week.

To save programs, press and hold the
button to return to the normal display.
By pressing the button once you can
now toggle between manual and timer
modes.

Set oor level

The button now controls the heat level
of your Devimat system. The controller
can be adjusted to the required heat level
on a range from 1-10, level 10 being the
maximum oor heat. The displayed heat
level is what the controller will provide
at the times programmed. It is recom­mended that you initially set to level 5,
then adjust to suit.

First start time

Rotate button to indicate the start of the
rst time period when you want a warm
oor (i.e. 06:00) and then press the button

First end time

Rotate the button to highlight duration of
rst warm oor period, then press button
to indicate the end of rst time period (i.e.
07:30)

If you multiply the level number by 5 it
will give you the temperature in °C.
Do not set this higher than the maximum
oor temperature.
