Settings service level
*NOTE: see Par. 6.1.4 for values over two digits
6.6.1 Flow temperature set point during forced part load (
$
)
Adjustable from 20 to 90°C, factory default 80°C
This value will prevent the flow temperature exceeding this temperature during the part
load time.
6.6.2 High limit thermostat (
%
)
Adjustable from 90 to 110°C (
!0
), factory default 100°C (
)0
).
This value sets the high limit temperature at which the boiler will shut down in a lock
out condition requiring manual intervention.
Note:
this parameter will have an effect on the minimum flow rate requirement,
see
Par. 7.4.7.
6.6.3 Fan speed at full load HTG (
^
)
Adjustable from 18 to 100% output (= 1100 (Quinta 45) / 1200 (Quinta 65) to 5200
rpm), factory default 52 (100%). This value sets the maximum output of the boiler.
6.6.4 Fan speed at part load (HTG and DHW -
&
)
Adjustable from 18 to 100% output (= 1100/1200 to 5200 rpm), factory default
11
(Quinta 45) /
12
(Quinta 65) (18% output). This value sets the minimum output of
the boiler.
6.6.5 Starting point modulation (
*
)
Adjustable from 5 to 30°C, factory default 25°C.
This value sets the flow/return
∆
t point at which the control modulation begins. If the
∆
t
continues to rise, at 40°C the boiler will be at minimum output (parameter
&
), at 45°C
the boiler will shut off (
code
b#)
,
see Par. 6.4
).
The factory default should be correct for most installations. Changing this value should
only be carried out on advice from the service engineer.
NOTE:
Installations with low flow problems would benefit by reducing this set point to
force modulation to begin sooner and minimise boiler off time.
