1.
Activation and deactivation
delay
is parameter is used to set the activation delay for all
appliances except the pin appliance.
e ignition delay of the appliances is not only given by
this parameter but also by the regulating algorithm.

2. KI factor compensation
is parameter slows down the integral part of the
control algorithm. If the activation of the appliances
aer the pin appliance is too slow, lower this value (the
use of the 'Activation and deactivation delay' parameter
is preferable in any case).

3. PI loop period
is parameter indicates how oen the calculation
of the control algorithm is performed. A lower value
makes the system faster but also more unstable, while
a higher value makes the system more stable but less
responsive to changes.

value
1. Maximum
Denes the maximum eective power of the individual
appliance. 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 lev-
el. If the maximum fan speed is changed, this parameter
must be adjusted to the new maximum power obtained.

2. Minimum modulation level
Denes the actual modulation ratio of the individual
appliance. 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 minimum ow rate as per the data sheet; in this case
this parameter should not be adjusted.
