1.1 Function
In control and monitoring mode, the unit regulates connected heaters to a given set-point (i.e.
target temperature). Monitoring is done based on preset temperature limits. If a limit is
exceeded or is not reached, potential-free contacts are switched (K3). The unit can be
configured for four different types of controller in the factory.
