Installation and service manual M2015/04b [EN]
Table 10: Menu structure in service mode, type E-ITN 10.6
Number of measuring cycles in single-sensor mode 7526. SM
Max. temperature of radiator sensor in last billing period 61.9°C SM
Date when max. temperature of radiator sensor in last billing period was
reached
3.12. SM
Min. temperature of radiator sensor in last billing period 25.4°C SM
Date when min. temperature of radiator sensor in last billing period was
reached
12.12. SM
Value for penultimate billing period 3258 SM
Values are not displayed in 6 s intervals like in user mode, it is necessary to press the button shortly to see
next value. If button is not pressed for 20 s, allocator switch back to the user mode. Switching to user mode
can be speed up by button long press (press and hold the button till --A-- appear on the display.
4.5.3.1. Number of measuring cycles in single-sensor mode
Number of measuring cycles is single-sensor mode in last billing period is displayed as e.g. 7526 SM
(without meaningless zeros). Maximal displayable value is 99 999. If this value is exceeded, E SM is
displayed.
4.5.3.2. Max. temperature of radiator sensor in last billing period
Maximal temperature of radiator sensor in last billing period is displayed as e.g. 61.9°C SM with accuracy to
one decimal place.
4.5.3.3. Date when the max. temperature of radiator sensor in last billing period was reached
Date when the maximal temperature of radiator sensor was reached is displayed as e.g. 3.12. SM.
4.5.3.4. Min. temperature of radiator sensor in last billing period
Minimal temperature of radiator sensor in last billing period is displayed as e.g. 25.4°C SM with accuracy to
one decimal place.
4.5.3.5. Date when the min. temperature of radiator sensor was reached in last billing period
Date when the minimal temperature of radiator sensor was reached is displayed as e.g. 12.12. SM.
4.5.3.6. Value in penultimate billing period
Value in penultimate billing period is displayed as e.g. 3258 SM. Value will be overwritten at 00:00:00 when
the new billing period begins.
4.5.4. Last year of battery life
Battery lifetime is programmed in the microprocessor memory and the last year of battery lifetime is indicated
on LCD by blinking of the special symbol: BAT. After finishing this time the symbol stays displayed
permanently. Calculated battery lifetime is 10 years + 1 year reserve.
4.6. ERROR MODE
In error mode the notice Error is permanently displayed and allocator does neither measure temperatures,
count the increase of consumption nor transmit measured data. Allocator just actualizes real time. Allocator
switches from working mode to error mode automatically after registration of serious error (e.g. fault in A/D
converter, when the power supply of microprocessor was interrupted and loss of data in RAM memory
occurred, etc.).
Allocator backups important data to permanent memory daily. Data in this memory are saved even if the
power supply is interrupted. Even in the case of battery failure these data are not lost. Saved data could be
read by special tools.
