The actual calculated output ratio is displayed. Cannot be
changed. Display in percent of installed heating power. Nega-
tive values for cooling.

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 =
OFF
b. P action
setting
D and I =
OFF
c. PD action
setting
I =
OFF
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.
