1 INTRODUCTION
E-ITN 10 is modern electronic device intended for ratio based allocation of heat cost in buildings with central
heating system
The heat cost allocator E-ITN 10 4 uses one (E-ITN 10 41) or two temperature sensors with surrounding
temperature sensor is used for start only (E-ITN 10 42) Allocators E-ITN 10 5x, E-ITN 10 6 and E-ITN 10 7x
are based on the two-sensor measuring principle Using this principle, allocator ensures measurement of
consumption value only when the radiator really emits heat (i e it does not measure in the summer)
E-ITN 10 is intended to be installed in one-tube horizontal/vertical and two-tube heating systems with the
lowest mean design heating medium temperature ≥ 35 °C or 55 °C (depending on type of the allocator, see
chapter 3 Technical specifications) and mean design heating medium temperature ≤ 90 °C
Each radiator in billing (account) unit with common invoicing heat meter must be equipped with a heat cost
allocator of the same type Technical conditions of heating system must be fulfilled when using heat cost
allocators E-ITN 10
E-ITN 10 is not intended for heat cost allocation for floor heating systems, ceiling radiant heating, flap
controlled radiators, radiators with fan, systems with steam heating medium, air heaters and single tube
radiators if exceeds the scope of one user It must not be also used for heating elements that shape and
design does not allow reliable transfer of heat to heat cost allocators
1 1 LC DISPLAY
Basic allocator status and measured values can be displayed on LCD LCD can display five alphanumeric
characters These values are highlighted by underline and overline in following text, e g 395
Meaning of some values may be different if the additional symbol „SM“ at the right bottom corner is
displayed These values are mentioned with „SM“ symbol in text , e g 385 SM
The last symbol on the display indicate end of the battery life, see chapter 4 5 4 Last year of battery life
To save the battery, after longer period of inactivity (approx 1 min ), energy-saving mode is activated and
display is switched off Display can be activated by pushing the button (Illustration 1: E-ITN 10)
