3.1. CONSTRUCTION
Electronic heat cost allocator E-ITN 10 complies with ČSN EN 834:1995.
Allocator consist of cover and printed circuit board with spring and push-button. Cover is 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 bar code) 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 lower end of the aluminium back plate, push up so that the
locks in the housing fit in the aluminium back plate and fix allocator with bolt M3x8 in this position. Then
secure the device with seal (marked seal should be inserted into the holes in the upper part of the allocator)
against unauthorized manipulation. Now the heat cost allocator can only be uninstalled after breaking the
seal.
Devices are equipped with a 16-bit microprocessor with extremely low current consumption 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 two special symbols.
Warning!
Spring on the printed board circuit is intended to maintain the good contact between temperature
sensor and base plate. Do not change the temperature sensor position or prestress of the spring.
