ACCESS TO THE ADVANCED SETTING
MENU (INST)
The gas-fired convector electronics allow for a range of
advanced settings and functions that can only be enabled
by the TAC.
The advanced settings menu (INST) is protected by an ac-
cess code; to access the menu, proceed as follows:
1. Press button B MENU
for more than 5 seconds; re-
lease it and press the MENU button again for another
5 seconds: the display will show "CODE".
2. Turn the knob counterclockwise until the code "987" is
displayed: press the knob to confirm the code.
3. The first displayed submenu is the "fault history"; brief-
ly press the MENU button to access the second sub-
menu "transparent control parameters".
Access to the "transparent control parameters"
submenu and any modification of them are the ex-
clusive responsibility of the TAC.
5.4.1
"Fault history" submenu
Accessing this menu, the display shows the letter "H" at
the top, followed by a progressive number (from H001)
and the error code in the centre (see Table 7.1
p. 29).
The display shows the errors codes that have occurred on
the gas-fired convector from the most recent (H001) to
the least recent (H010).
To scroll through the faults, turn the knob. Up to 10 faults
can be displayed.
5.4.2
"Transparent control parameters"
submenu
On accessing this menu the display shows at the top the
