CH ignition delay
from TA and CR
request
e boiler is set to switch-on immediately aer a request. In the event
of particular systems (e.g. area systems with motorised thermostatic
valves etc.) it may be necessary to delay ignition

t7 Display lighting
Establishes the display lighting mode.
- 0: the display lights up during use and lowers aer 15 seconds of
inactivity. In the case of anomaly the display ashes.
- 1: display lighting o.
- 2: the display is always lit up.

t8 Display
Establishes what the indicator displays 19 (Fig. 37).
"Summer" mode:
- 0: the indicator is always o.
- 1: circulator active, it displays the ow temperature,
pump o the indicator is o
"Winter" mode:
- 0: it always displays the value set on the central heating selector
- 1: circulator active, it displays the ow temperature,
pump o always displays the value set on the CH selector

increase
Increases the ow o temperature at ignition only in the rst 60 sec-
onds. Aer the ame is detected, the temperature is increased by t9

A4
Storage tank ow
oset
Establishes the temperature to be added to the DHW set-point to cal-
culate the ow set to heat the storage tank (only useful with a coupled
storage tank and parameter A0=1).
5 - 50 °C 25
A5
Storage tank
activation oset
Temperature value to be subtracted from the DHW set-point to cal-
culate the boiler ignition to heat the storage tank (only useful with a
coupled storage tank and parameter A0=1).
0 - 15 °C 3
A6 DHW thermostat
Establishes the switch-o method in DHW mode.
- 0 Fixed: the switch-o temperature is xed at the maximum value
regardless of the value set on the control panel.
- 1 Correlated: the boiler switches o according to the temperature
set.
