Electronic heat cost allocator E-ITN 30.xx EX with external sensor
Data reading
Due to integrated radio transmitter, presence of flat occupant is not required when data are read. Data reading can be made by billing company employee using mobile receiving unit RFU 35 from outside of the house.Protection against cheating
Both the allocator and the remote sensor are equipped with a mechanic and an electronic seal. The allocator is delivered in sealed state with both electronic seals activated.If either electronic seal is violated the allocator saves the date of breach of the electronic seal to its memory and stops to show measured data on the display. Only the notice oPEn is displayed and indicates breach of one or both electronic seals.
The allocator continues in measuring and transmitting of measured data. Information about breach of the electronic seal is available in data transmitted by radio module and in data transferred via IR interface.
Application
E-ITN 30 is intended to be installed in one-tube horizontal/vertical and two-tube heating systems with the lowest mean design heating medium temperature tmin ≥ 35 °C and highest mean design heating medium temperature tmax ≤ 105 °C.Technical data
| Measuring principle | two-sensor measuring principle |
| Conditions for measuring | sensor temperature of the radiator ≥ 23 °C temperature difference between the mean heating medium temperature and the reference air temperature <= 5 K (according to standard EN 834:2013), different conditions for registration in the summer period |
| Resulting rating factor K | depends on the type of allocator, see. manual |
| Calendar functions | depends on the type of allocator, see. manual |
| Data imaging | 5-dial LC display + 2 special symbols |
| Data reading | 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 |
| Data backup | daily backup of measured values including real time |
| Function control | automatic, can be activated and controlled by user |
| Dimensions | allocator 100 x 37 x 40 mm, sensor 21 x 37 x 45 mm |
| Power supply | lithium battery 3,0 V |
| Material | ABS + PC / Al - F22 |
| IP code | IP 42 |
| Conformity | EN 834 |
Technical data of the radio part |
|
| Operating frequency | 868 MHz |
| Transmitting power | < 5 mW |
| Transmission length | depends on the type of allocator, see. manual |
| Transmission range | 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. |
| Data coding | yes |
