* When a line has a “*” at the end, pressing OK when the line is highlighted will open a graph showing the last 120 variable values stored every 12 minutes (24-
hour history). e sample will not be averaged over the 12-minute period.

1. Maximum
Denes the maximum eective power of the individual ap-
pliance. is parameter is used within the control algorithm.
If the maximum power is changed via the 'Maximum power'
parameters (DHW and heating), this parameter should not
be adjusted, as depowering acts at the cascade level and not
at the individual appliance level. If the maximum fan speed is
changed, this parameter must be adjusted to the new maxi-
mum power obtained.

2.
Minimum modulation
level
Denes the actual modulation ratio of the individual appli-
ance. is parameter is used within the control algorithm. If
the maximum power is changed via the "Minimum power"
parameters (DHW and heating), this parameter should not be
adjusted, as the change in power acts at the cascade level and
not at the individual appliance level. If the minimum fan speed
is increased, it may be necessary to adjust this parameter.
Note: with collective ue system use, the minimum fan speed
is increased to bring the individual appliances to the mini-
mum ow rate as per the data sheet; in this case this parameter
should not be adjusted.
