4. ELECTRICAL SYSTEM AND CONNECTION RULES
1. The boiler room should be equipped with a 230V/50Hz electrical system, according to the
applicable regulations.
2. The electrical system (regardless of its type) should be terminated with a connection outlet fitted
with a protective terminal. Use of an outlet without a protective terminal causes electrical shock
hazard!!!
3. Connect the Controller to a separately installed power line protected with a properly selected
quick circuit-breaker or a residual-current device (RCD breaker). Do not connect any other devices
to this line!!!
THE CONTROLLER IS POWERED FROM 230V/50HZ MAINS
ANY REPAIRS MAY BE CARRIED OUT ONLY WITH POWER SUPPLY
CUT OFF AT THE FUSE

6.5. Alarm Conditions
The Controller uses 8 different alarm conditions. In each alarm condition, the Controller displays the
alarm number and activates the alarm sound output. In case of several alarm conditions occurring
simultaneously, their numbers are displayed in sequence. You can exit an alarm condition only by pressing
. This does not include the AL12 alarm condition.
Alarm conditions:
AL1
STB activated or fuse blown
AL2
Boiler water outlet temperature sensor failure
AL3
Feeder temperature sensor failure
AL4
HUW/return temperature sensor failure
AL9
No feeder rotation / reed switch failure
AL11 Maximum feeder temperature exceeded
AL12 Boiler overheating
AL13 Boiler burnout
6.6. Power Failure
After a power failure the Controller starts to reactivate according to the condition it was in before the
power down. The Controller waits 1 minute to stabilise the mains power parameters, and then restores
operation with the previously programmed settings.
During the waiting period, the display shows time in seconds remaining until the end of the period,
along with indication of its condition before the power outage:
blinking “A” for AUTO mode,
blinking “P” for MAINTAIN mode,
blinking “r” for MANUAL mode.
Respective indicators (AUTO or MAINTAIN ) are blinking along with the letters.
