Definition of switch-on and switch-off
temperatures for heating.

Definition of switch-on and switch-off
temperatures for heating.
Only if "type of heating control" = "2-state".
Selects a control algorithm (PI or 2-state) with
data format (1 byte or 1 bit) for the cooling
system.
Only if "Transmit actuating variables for heating
and cooling to shared object" = "no".
If "Transmit actuating variables for heating and
cooling to shared object" = "yes", the parameter
settings for "Type of heating control" will be
accepted.
Adapts the PI algorithm to different cooling
systems using experience values for the
proportional range and reset time control
parameters.
Separate input of control parameter.
Separate setting of the "proportional range"
control parameter.
Only if "Type of cooling" = "via control
parameter".
Separate setting of the "reset time" control
parameter.
Only if "Type of cooling" = "via control
parameter".
