Zone setting
Each zone is configured for the area of competence via the dip switches mounted on the
associated board (see above), and by entering on the boiler board the number of
connected additional boards (max. 4) by setting parameter P60.
If control of zones 1 and 2 differs from standard control (remote control assigned to zone2
and ambient thermostat to zone1), you change the combination via parameter P61.
At this point, you can access parameter setting for each zone:
Zone 1:
Parameter P10 setting to enter the thermoregulation curve (with an external probe)
or the operating range (without an external probe).
Regulation via the heating button of the fictitious ambient temperature (with an
external probe) or the fixed-point flow value (without an external probe) according to
the selected range. Parameter P32 displays the calculated flow temperature, and
parameter P31 the current value read by the boiler probe.
Zone 2:
Parameter P62 setting to enter the thermoregulation curve (with an external probe)
or the operating range (without an external probe).
Regulation of the fictitious ambient temperature via parameter P63 (with an external
probe) or the set-point flow value (without an external probe) according to the
selected range. Parameter P33 displays the calculated flow temperature, and
parameter P34 the current value read by the boiler probe.
Important. If zones 1 or 2 are remote controlled, 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), and regulation of the set-point (without an
external probe) or the fictitious temperature (with an external probe) must be carried out via
the remote control.
Zone 3:
Parameter P66 setting to enter the thermoregulation curve (with an external probe)
or the operating range (without an external probe). Regulation via parameter P67 of
the fictitious ambient temperature (with an external probe) or the set-point flow
value (without an external probe) according to the selected range. Parameter P36
displays the calculated flow temperature, and parameter P37 the current value read
by the boiler probe.
