13.2.10 High limit temperature setting (G)
Parameter G, adjustable between 90 and 110°.
This value sets the high limit temperature at which the
boiler module will shutdown in a lockout condition requir-
ing manual intervention.

Important!!
If the factory setting is reduced, a
corresponding reduction in flow setpoint will be required
otherwise the min flow rate may be effected.
13.2.11 Modulation start point at dT (H)
Parameter H, adjustable between 10 and 30°.
This value sets the flow/ return dT point at which the
control modulation begins. The boiler module starts to
modulate at the setpoint and will be at minimum output if
the dT continues to rise to 40°. At 45° the boiler mod-
ule will shut (shut-off code b #)). For installations
with low flow rates the starting point modulation can be
brought forward (i.e. 15°), closer matching boiler output
to system demand. In systems with small volume flows
the modulation start point can be brought forward. The
boiler module is better equipped to anticipate low heat
demand.
The factory setpoint should be correct for most instal-
lations. The start point should only be changed if abso-
lutely necessary.
13.2.12 Minimum water pressure (I)
Parameter I, adjustable between 0.8 and 6 bar.
This setting only applies if an optional hydraulic pres-
sure sensor has been connected.
This value sets the point at which the boiler module
will shutdown if the system pressure falls below it. The
boiler module will resume normal operation when pres-
sure is restored.
13.2.13 Adjustments options/ accessories (J)
Parameter J, adjustable between 0 and 15.
This setting is only applicable if options from table 21
are connected to the boiler module. The control unit
detects which options have been connected by means
of the value of this parameter and adjusts the boiler con-
trol on this basis.
The required feedback message (as output in % or
as temperature in °) can also be selected here if the
(standard) analog output is used. A list of values that
have been assigned to specific options can be found in
table 21. Adding together the values of the options used
gives the parameter J.

Parameter J:
table 21 Adjustments options/accessories
Examples:
- Factory setting is 0: the analog output will be in %.
- Water pressure sensor (1) and valve leak proving
system (8) options are connected: parameter J is
set to (1) + (8) = 09.
13.2.14 "Low" speed with H/L control (L)
Parameter L, adjustable between 10 and 60 (x 100) rpm.
This setting only applies if the boiler module is in High/
Low control mode (parameter A = 21).
13.2.15 Boiler type (P)
This code appears only when replacing the control unit.
After placing the new control unit, code P05 appears
automatically in the display. The value 05 must be
changed in to the correct value for your boiler type (see
mounting-instructions of the service unit).
