average incoming water temperatures. The combination of
these two occurrences can result in short-cycling when
used in conjunction with preheating.

PREHEATING
TOUCH & GO
By setting parameter PREHEATING = 2 the function Touch&Go is
activated. This function allow you to activate one preheating
cicle
by open and close the water tap just before an hot water request.
SLIDING OUTLET (heat only boiler)
The SLIDING OUTLET function modifies the outlet setpoint used by
the boiler when receiving a DHW request. The factory setting for
this parameter is FUNCTION NON ACTIVE; this setting performs a
modulation to a fixed outlet value of 176°F (80°C) when there is a
DHW request. Select FUNCTION ACTIVE using the “up” and “down”
buttons, confirming the selection. In this case, the outlet
setpoint in a DHW request is no longer fixed at 176°F (80°C) but
variable, and it is calculated automatically by the boiler based
on the difference between the desired DHW setpoint and the
temperature value detected by the indirect tank sensor.
Note: we do not recommend activating this function for water
tanks with a capacity of over 26 US gallons (100 liters) since the
water tank filling would be too slow.
NOTICE
: it may be necessary to set the value of this parameter
again after replacing the PCB.

The following parameters will be also available by
accessing technical parameters with a SERVICE authorization
level:
HYST ON HIGH TEMP
This parameter allow you to change the central heating setpoint
value detractor for burner ignition on high temperature zone
type
Range 2sec - 10sec, factory setting 5sec
HYST OFF HIGH TEMP
This parameter allow you to change the central heating setpoint
value add for overtemperature burner power off on high
temperature zone type
Range 2sec - 10sec, factory setting 5sec
HYST ON LOW TEMP
This parameter allow you to change the central heating setpoint
value detractor for burner ignition on low temperature zone type
Range 2sec - 10sec, factory setting 3sec
HYST OFF LOW TEMP
This parameter allow you to change the central heating setpoint
value add for overtemperature burner power off on low
temperature zone type
Range 2sec - 10sec, factory setting 3sec
SP INCR HIGH TEMP
This parameter allow you to change central heating control
setpoint offset on high temperature zone type
Range 0sec - 10sec, factory setting 0sec
SP INCR LOW TEMP
This parameter allow you to change central heating control
setpoint offset on low temperature zone type
Range 0sec - 10sec, factory setting 0sec
CH DELAY POST-DHW
This parameter allow you to enable central heating delaying at
the end of an hot water request:
0 = function disabled (factory setting)
1 = function enabled
CH DELAY TIME
When CH DELAY POST-DHW is enabled, this parameter allow you to
setup the central heating delay time in teh range 1sec - 255sec,
6sec is the factory setting
WATER TRANSDUCER
This parameter allow you to setup the water pressure transducer
type:
0 = water pressure switch
1 = water pressure transducer (factory setting)
AUTO WATER FILL ENABLE
When WATER TRANSDUCER = 1, this parameter allow you to enable
a water fill valve management:
0 = function disabled (factory setting)
1 = function enabled
BEGIN SYSTEM FILLING
When AUTO WATER FILL ENABLE = 1, this parameter allow you to
setup the water pressure threshold for auto fill
DHW DELAY
This parameter allow you to setup an hot water request burner
ignition delay in the range 0sec - 60sec. 0sec is the factory
setting.

Configuration of the zone
It is possible to customize the management of the heating
zone by accessing the ZONES MANAGER menu.
- Access the technical parameters as explained in the
section “11.6 Access to the technical parameters”.
- In sequence, select INSTALLATION, ZONES MANAGER
and MODIFY ZONE with the “up” and “down” buttons,
confirming the selection by pressing the “ENTER” button.
