Due to integrated radio transmitter, presence of flat-occupant is not required when data are read. No strangers also enter the flat.
Data reading can be made by billing company employee using mobile receiving unit. Data can be also read by central reading system CRS 40 permanently installed in the building if required.
If water meters with radio modules E-RM 30 are also used, data are read simultaneously.
Every user can control current value during actual billing period and archive value for past billing period on LC display. LCD is placed for better accessibility on the top side of the fashionably designed allocator.
- current value in actual billing period
- archive value for past billing period
- control alphanumerical code
- first part of allocator serial number
- second part of allocator serial number
Protection against cheating
Heat cost allocator E-ITN 30 is equipped with electronic seal. This seal is able to recognize unauthorized manipulation and record its exact date. Data about unauthorized manipulation is transmit in radio signal.
When thermally influenced, allocator is switched to single-sensor mode. Allocator is switched back to standard two-sensor mode when thermal influence is finished. Consumption values and radiator temperatures for past 12 months can be read from the allocator memory via infra-red interface.
E-TIN 30 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 and highest mean design heating medium temperature ≤ 90 °C.
||two-sensor measuring principle
|Conditions for measuring
||temperature of the sensor of the radiator temperature ≥ 23 °C
difference of surroundings temperature and mean temperature of heating medium ≥ 4 °C
|Resulting rating factor K
||K = 1
||value for past year,
for past 12 months: month consumption value, min., aver. and max. radiator temperature, number of heating days
||5-dial LC display + 2 special symbols
||visually, radio and infra-red interface
|Protection against cheating
||continuous control of surroundings temperature, if the thermal influence is detected, allocator is switched to single-sensor mode
electronic seal records manipulation date when uninstalled
||daily backup of measured values including real time
||automatic, can be activated and controlled by user
||100 x 37 x 33 mm
||lithium battery 3,0 V
||ABS + PC / Al - F22
Technical data of the radio part
||< 5 mW
||up to 250 m (without entering the building, with additional panel antenna)
Rem.: it is necessary to consider that all metal parts of construction (armouring, lifts, switch rooms, etc.) can negatively affect the range of radio signal.
