7 .6 DOMESTIC HOT WATER NTC SENSOR
When a sensor failure occurs in hot water system, H2 warning code appears on LCD screen.
7 .7 CENTRAL HEATING NTC SENSOR
When a sensor failure occurs in central heating system.H1 warning code appears on the LCD
screen
7 .8 HIGH WATER PRESSURE PROTECTION
When there is over pressure in the heating system, the 3 bar safety valve discharges water
and decreases the pressure.
7 .9 PRECAUTION AGAINST PUMP LOCK
When the boiler is in the OFF position, the pump is operated in every 24 hours by the control
card for a certain period of time to prevent locking and jamming of the pump.
7 .10 MOTORISED VALVE SAFETY
When the boiler is in the OFF position, the 3-way valve is operated in every 24 hours by the
control card for a certain period of time. The motorized valve returns to its previous position
after a certain period of time after changing the position.
7 .11 AUTOMATIC BY-PASS
If there is thermostatic valve one each radiator, even when all thermostatic valves are switched
off, there is an automatic by-pass system in order to provide of passing of minimum water flow
in order to prevent rapid over heating of the boiler.
8. MAINTENANCE
We recommend that the following controls are made by authorised service once a year.
1-Check for leaks in the water circuit and, if necessary, replace the joints to ensure water
tightness.
2-Check the status of the device visually.
3-Check the safety system of the heating system if it is working properly. Heat limit and safety
thermostats artificially and check that they are functioning.
4-Check all electricity connections of the device. Fasten any loosened cables.
5-Check the operation of resistances with required measurement equipment.
6-Check the hot water production efficiency as flow and temperature.
7-Check the general operation of the device.
CAUTION!:
Especially during winter, when the ambiant temperature decreases below 0°C
there is a risk of freezing and the system water must be drained if the electrical connection of
the device is interrupted during these periods.
WARNING! : Make sure to cut off the electricity from the short circuit relay before making
any maintenance or repair on the boiler.
