Description
Establishes the switch-off method in DHW mode.
1 Correlated: the boiler switches off according to the temperature
set.
0 and 2 Fixed: the switch-off temperature is fixed at the maximum
value regardless of the value set on the control panel.
The boiler is set to switch-on immediately after a request. for DHW
In the case of coupling with a solar storage tank positioned upstream
from the boiler, it is possible to compensate the distance between the
storage tank and the boiler in order to allow the water to reach the
boiler. Set the time necessary to verify that the water is hot enough
(see par. Solar panels coupling)
The pump can function in two ways.
0 intermittent: in winter "mode" the circulator is managed by the
room thermostat or by the remote control
1 continuous: in "winter" mode the circulator is always powered
and is therefore always in operation
The boiler is set-up for functioning with the relay P.C.B. (option-
al), which can be configured
0 = Off
1 = Main zone control
2 =General alarm
3 = CH phase active
4 = External gas valve power supply
5 = (Do not use on this boiler model)
The boiler is set-up for functioning with the relay P.C.B. (option-

2 = CH phase active
3 = External gas valve power supply
4 = Secondary zone control (from TA on relay P.C.B. contact)
5 = Heat pump
