Creep feed rate limitation using a binary input

It is possible to report to the controller when the creep feed rate has fallen below a certain level
by using a limit switch of the primary valve connected to the terminals 04/12. Either the open
(bE=0) binary input or the closed binary input (bE=1) can be assigned to inform about the creep
feed rate status. Shortly after the alert, the controller closes the valve Rk1. As soon as the flow
temperature falls below the set point by more than 5 °C after the valve has been closed, control
operation is started again.

Locking manual level

To protect the heating system, this function can be used to lock the manual level. When this func-
tion has been activated, automatic mode is started when the rotary switch is set to
matic mode.
