-
Green flashing
boards with no request;
-
Red flashing slow-slow (1s on, 1s off)
faulty communication with boiler board;
-
Red steady

Red green steady
flow probe fault with error E36 on the boiler display;
Zone setting
The zones are set with the relevant zone configuration by means of the dip switches on
the zone board (see previous paragraph), and then indicating on the boiler board how
many supplementary boards are connected through parameter P60 setting (max. 4).
In case of zone 1 and 2 management different than the standard one (remote control
associated with zone 2 and ambient thermostat with zone 1), change the coupling using
parameter P61.
It is now possible to access the parameter programming for each single zone:
Zone 1:
parameter P10 setting to set the thermoregulation curve (with external probe) or the
operation range (without external probe).
Adjustment, through heating key, of the fictitious ambient temperature (with external
probe) or of the flow value at fixed point (without external probe) according to the
selected range. Parameter P32 displays the calculated flow temperature, whereas
parameter P31 the current one detected by the boiler probe.
Zone 2:
parameter P62 setting to set the thermoregulation curve (with external probe) or the
operation range (without external probe).
Adjustment through parameter P63 of the fictitious room temperature (with external
probe) or of the flow value at fixed point (without external probe) according to the
selected range. Parameter P33 displays the calculated flow temperature, whereas
parameter P34 the current one detected by the boiler probe.
Warning: with remote control for managing zones 1 or 2, the boiler board communicates to
the remote control the minimum and maximum flow limit according to the curve set by the
relevant parameter (reduced or standard range), whereas the setting at fixed point (without
external probe) or of the fictitious temperature (with external probe) must be carried out with
the remote control.
Zone 3:
parameter P66 setting to set the thermoregulation curve (with external probe) or the
operation range (without external probe). Adjustment through parameter P67 of the
fictitious ambient temperature (with external probe) or of the flow value at fixed point
(without external probe) according to the selected range. Parameter P36 displays
the calculated flow temperature, whereas parameter P37 the current one detected
by the boiler probe.
Zone 4:
parameter P70 setting to set the thermoregulation curve (with external probe) or the
operation range (without external probe). Adjustment through parameter P71 of the
fictitious ambient temperature (with external probe) or of the flow value at fixed point
