Configuring the Switching Outputs and the Continuous Output
As a standard feature, a 2-step heating controller is configured to switching output out1 (transistor output).
Control performance (2-step heating or cooling, 3-point discontinuous, step-action controller, continuous-action controller, split range controller) is
determined by the configuration selected for the actuating outputs. See also the “Configuration” table on page 16.
– Actuators for heating and cooling are selected independent of each other (this allows for the combination of, for example, step-action control for
heating, as well as for cooling.)
– If 2-step control is required, heating and cooling outputs may not be configured simultaneously for the respective controller.
– Several switching outputs can be assigned to the same controller output for separate control of several actuators with a single controller output.
– If a continuous and a discontinuous output are both configured for heating (or cooling) at the same time, the channel performs like a
continuous-action controller and the discontinuous output is inactive.
– If, inadvertently, only one “Less” output is configured for heating (or cooling), it remains inactive.
– The settings can be freely combined regardless of
controller type
and
controller sort
.
Relay Outputs for Actuating Signals
If, in the case of device variant A1 or A4, two relay outputs are required for the actuating signals, for example in the case of three-step or step-action
control, the alarm outputs can be exchanged with the actuator outputs.
The
Out = XCh
configuration (see page 16) exchanges the functions of
out1
with
A1
and
out2
with
A2
.
