0 … 100%
The actual calculated output ratio is displayed. Cannot be
changed. Display in percent of installed heating power. Nega-
tive values for cooling.
H L y
Max. output ratio limitation
"heating"
>PID<
0 … 100%
Max. output ratio limitation is only necessary for strongly
over-sized heating power supply. Under normal conditions
output ratio limitation is not necessary (setting: 100 %).
The limitation intervenes if the calculated output ratio is
higher than the adjusted max. output ratio limitation value.
Warning! Output ratio limitation does not work during auto-
tune.

Adjustment of Control Parameters:
Normally the controller operates in PD/I control mode, without control deviation and
largely without overshoot during start-up.
The control action can be altered by adjusting following parameters:
a. no control action, on-off setting P = OF F
b. P action setting D and I = OF F
c. PD action setting I = OF F
d. PI action setting D = OFF
e. PD/I modified PID-mode (set P, D, I)
According to the configuration, certain parameters
are not visible.
