Electronic heat cost allocator E-ITN 40 complies with ČSN EN 834:2014.
Allocator consist of cover and printed circuit board covered with mounting plate. Mounting plate is bolted with
cover and secured with latch and seal.
Cover, mounting plate, latch and seal are made from plastic material. There are marked values of the lowest
and highest heating medium temperature, manufacturer's mark, type of the allocator, serial number (both as
number and 2D data matrix) and optionally the partner's mark on the cover. The base plate is made of
aluminium alloy to ensure of a good thermal contact with the radiator.
To install the heat cost allocator, place it at the upper end of the aluminium back plate, push down so that
the locks in the housing fit in the aluminium back plate and push the bottom part of allocator towards back
plate. Allocator is fastened to back plate by latch and seal. Now the heat cost allocator can only be uninstall
after breaking the seal.
Device has an electrical circuitry with a 16-Bit microprocessor with extremely low current consumption, is
equipped with radio transmitter and powered by lithium battery. The accuracy of the measuring circuit is
independent of the battery voltage. The LCD-display has 5 large main digits separated by dots and special
symbols.
