8 Parameters
8.8 P8x - Switch-o
Parameter
P8x
Designation Description Setting
P80 Regular switch-o:
Transition time
Using this parameter, a transition
time can be activated in which the
MPA remains after the failure of the
temperature controller / heat re-
quest. The ame remains burning.
During this time, the MPA moves to
the modulation degree dened in
P81.
This function can be used to avoid
that the MPA switches o in an un-
desired modulation degree.
Attention! This setting can only be
applied for the regular switch-o. In
case of a safety switch-o, the MPA
switches o without changing the
modulation degree to the desired
setting.
P81 Regular switch-o:
Power during transi-
tion
This value denes the desired
modulation degree for a regular
switch-o. Chose the value so that
no undesired noise or vibrations
are generated during the regular
switch-o.
Attention! A suciently long transi-
tion time after a regular switch-o
(P80) must be dened in order to
reach this modulation degree.
Attention! This setting can only be
applied for the regular switch-o. In
case of a safety switch-o, the MPA
switches o without changing the
modulation degree to the desired
setting.
P82 Follow-up time See state: "Follow-up time".
Denes the time during which the
external light is not monitored after
a regular switch-o.
P83 Post-aeration time Denes the post-aeration time after
a regular switch-o.
Attention! After a safety switch-o,
this post-aeration is not carried
out!
P84 O-period before
restart
Denes the duration of the compul-
sory waiting time until the automat-
ic burner control is allowed to start
again.
