NOTE:
When using an external analog (0 -10V) or 2 wire modulation input, the factory
default
03
should be changed to
00
.
Parameter

)
Adjustable from

30
°C factory default 20°C.
Refer to Par. 6.6.7.
6.6.11 DHW control option (

6.6.12 HTG cut in temp (
N
)
Adjustable
1)
(-10) to
20
°C, factory default
03
.
This value sets the
∆
t below actual return temp at the moment of control stop during
HTG demand.
A control stop occurs when the flow temp equals the flow temp set point + 5°C.
HTG cut in temperature = actual return temperature at the moment of control stop (e.g.
60) - parameter
N
(3)
ie 60 - 3 = 57°C
If this takes longer than the maximum delay time (parameter
U
), the boiler will restart
(unless flow temperature exceeds flow temperature setpoint).
Parameter
O
not applicable
6.6.13 Boiler type (
P
)
Factory default
44
(Quinta 45) and
64
(Quinta 65), must not be changed.
Parameter
T
factory set must not be changed.
6.6.14 Maximum delay time (
U
)
Adjustable from
00
-
99
minutes, factory default 15 minutes (
15
).
This value sets the maximum off time following a control stop. The minimum off time is
preset to a fixed value (150 sec.).
A combination of both values is used to prevent hunting taking place.
