depress

button and hold it for 3 seconds to confirm selection. All LED indicators go in for a
while to confirm the settings. If the selection is not confirmed within 5 seconds the attempt the
change settings is cancelled and the module moves to regular operation.

Troubleshooting
The EcoAlpa5 Control Unit offers basic self-test functions that enable:
monitoring of communication lines and detection of line breaks,
monitoring of voltages and content of internal memories,
operability tests of rechargeable batteries,
checks whether a shutoff valve with the 12 V control voltage and/or an additional ZMZ module
are correctly connected,
• failure (break) of the control line for transmission of shut off signals,
• failure (break) of the line for connection of an additional ZMZ module.
8.5.1
Test of the user interface
The test is initiated by short depression of the
TEST
button, which triggers activation of all indicating LEDs of
the device for about 1 second and horning of the internal buzzer (the same test is also launched after each
power up of the device).
In case when any irregularity of the device operation is spotted please contact the device manufacturer.
8.5.2
Test of the shutoff valve
The control unit offers also the functionality to test the gas shutoff valve.
The need to run the test is indicated by slow blinking of the TEST indicator and is reminded after each three
months from execution of a previous test.
The test is initiated by an operator from the level of the control unit. Prior to execution of the test please
make sure that a short-term interruption in supply of gas is safe and harmless at the moment (observe the
procedures effective for the entire system). To run the test please follow the following procedure:
depress the
TEST
button and hold is depressed for about five seconds, the TEST indicator light up
and remain continuously on,
check whether the valve is reliably closed,
open the valve.
If any irregularity of the shutoff valve actuation to close the supply line is spotted please contact the device
manufacturer of a service company.
Initiation of the shutoff valve test is infeasible when the control unit indicates failure of the
valve itself (see Table 6) or its battery (see Table 7).
