Always connect the Devidry™ CD
between the power source and the
Devidry™ element. Connect the Devi-
dry™ floor heating system in accordance
with national standards and wiring
rules. Every fuse has its protective value
imprinted in Ampere (e.g. 10, 13 or 16 A).
Multiply this number by the mains volt-
age (e.g. 230 Volt) to find the available
output.
Example: Ampere (I) multiplied by Volt
(U) equals Power (P):
I x U = P
13 Amp x 230 V = 2990 Watt
When calculating the output available
for the Devidry™ system, you should
take all you electrical appliances on
this fuse into consideration. If you are
in doubt about which fuse covers the
particular floor area, you can simply turn
it off and see what appliances that are
not working.
You can typically find the power of your
electric appliances imprinted as wattage
on the back of the product. The ‘power’
of your fuses minus the total power of
your appliances equals the remaining
power that is available for your Devidry™
floor heating system. Calculate the avail-
able power for your Devidry™ floor heat-
ing system using the following table:
Calculation example
Fuse in the distribution board (e.g. 16 A x 230 V)
3.680 watt
