LIMITER
The controller can also be used as a limiter. If the actual value
of the heating circuit exceeds the set limit value, the limiter
switches off the heating circuit (via the safety relay) and locks
it. In order for the heating circuit to be unlocked again, the
actual value must first fall below the limit value. In addition,
the unlocking must be confirmed on the limiter (with DigIn2
or by pressing„ “ for 5 seconds).
The set limit value may only exist as a fixed setpoint, so the
only options are an external setpoint or setpoint W1.
