By pressing the enter key you can confirm the menu or the position.
When you keep pressing the enter key, you can by pressing the
arrow key (at any Pos. and/or menu) get back to the different levels
or by simultaneously pressing the enter key and the arrow key you
can get back to the previous menu position.
After 3 minutes the display of the integrator switches automatically
back to the main menu.
7.4.3 Error messages
If a fault should occur with the heat meter, an error message will
be displayed on the intergrator LCD screen. This will be Err-sign
together with a numbered code. If several errors occur at the same
time, the numbers of the error codes are added.
The possible error messages are as follows:
Err1
The supply sensor is short circuited or disconnected
Err2
The return sensor is short circuited or disconnected
The temperature sensors are switched; the temperature
sensor in the return (cooler) pipe is higher than the
temperature sensor in the (flow) warmer pipe
Err4
The flow rate too high for the flow meter
Err8
EEPROM error in the integrator base (only active after the
second incident)
Err16
EEPROM error in the measurement and calibration part
(only active after the second incident)
Err32
Configuration error into the measurement and calibration
part
Err64
Configuration error into the integrator base
Err128 Internal electronic failure, return to manufacturer
Err256 Voltage drop (by mains supply or bus supply)
Err512 Defective communication module connection place 1
Err1024 Defective communication module connection place 2
Err2048 Error pulse inputs additional meter A1
Err4096 Error pulse inputs additional meter A2
Err8192 Internal electronic failure, return to manufacturer
If an error lasts longer than an hour, the error will be registered in
the error register with its date and time (beginning) and duration (in
minutes).
When an error lasts less than 60 minutes the error will be
automatically deleted without being memorized.
The two temperature sensor indicators are displayed on the
cumulated energy by the main menu when:
- Temperature sensors are switched - this installation error mode
happen with most installations during the summer time
- Temperature in the cooler line is higher than the one in the warmer
line.
These error messages are automatically deleted from the LCD
display 60 seconds after the error has been removed.
7.4.4 Battery back-up
The integrator unit is fitted with a back-up battery. This is supplied
factory fitted with a jumper that permits activation or de-activation of
the back-up battery.
For the back-up battery function to be activated, the jumper MUST
be fitted. Refer to Figure 7-21. DO NOT remove this jumper as this
will result in the battery back-up function being de-activated.
