METEO GREEN HE R.S.I.
WORKING THE BOILER
Adjust the ambient thermostat to the required temperature (approx. 20°C).
If there is a demand for heating water, the boiler starts and the symbol
is shown on the display (Fig. K). The boiler will remain working until the set
temperatures are reached, after which it will go on stand-by. In the event of
ignition or operating faults, the boiler will perform a “safety stop”.
The flame symbol will go out and the fault code and
will be displayed
(Fig. L). For a description of faults and how to reset them, consult chapter
“Troubleshooting”.
17.2 - SWITCHING OFF
Switching off for short periods
For brief absences press the button to switch off the boiler. The display
will show two segments in the central area (Fig. M). When the boiler remains
powered with the gas tap open, it is protected by the following systems:
- anti-freeze: when the temperature of the water in the boiler falls below
safety values, the circulator and the burner work at minimum power to
increase the water temperature to a safe value (35°C). The
symbol
lights up on the display.
- circulator anti-block: one operating cycle is performed every 24 hours.
Switching off for long periods
For prolonged absences press the button to switch off the boiler (Fig. D).
The display will show two segments in the central area. Turn the main switch
to “off”.
Turn off the gas tap under the boiler by turning it clockwise (Fig. N).
In this case, the anti-freeze and anti-block systems are disabled . Empty
the water circuit or suitably protect it with a good make of anti-freeze .
17.3 - BOILER FUNCTIONS
Filling the circuit
If circuit pressure reaches 0.6 bar, the pressure value flashes on the dis-
play (Fig. O); if it falls below a minimum safety value (0.3 bar), fault code
41 appears on the display (Fig. P) for a certain time, following which, if the
fault persists, fault code 40 is displayed (see chapter on “Troubleshooting”).
In the event of faul 40 (Fig. Q) proceed as follow to restore the correct pres-
sure value:
- press button
- open the filling tap external to the boiler, until the pressure shown in the
display is between 1 and 1,5 bar.
If you have to fill the system several times, contact the Technical Service
Centre to check whether the heating circuit is watertight (see if there are
any leaks).
Information
Press , the display turns off and just the word InFO appears (Fig. R). Press
the button to view operating information. Press the button again to move
on to the next piece of information. If the button is not pressed, the system
automatically exits the function.
Info list:
Info 0 - shows the word InFO (Fig. R)
Info 1 - only with the external probe connected, displays external temperature
(e.g. 12°C) (Fig. S). The values shown on the display range between - 30°C
and 35°C. Beyond these values the display shows “- -”
Info 2 - shows circuit pressure (Fig. T)
Info 3 - shows the set heating temperature (Fig. U)
Info 4 - shows the setted temperature (only water tank with sensor, Fig. V)
Info 5 - displays the set heating temperature, in reference to the second
circuit, only if it is connected.
S.A.R.A. function (Fig. W)
If the “winter” mode is selected, the S.A.R.A. function is activated for the
heating circuit. This function allows to reach the required ambient tempera-
ture more quickly.
Depending on the temperature set on the ambient thermostat and the time
taken to reach it, the boiler automatically adjusts the heating water tem-
perature to reduce operating times, thereby increasing operating comfort
and energy saving.
