A1/A2 Function of regulation contacts ½
Regulation contacts 1 and 2 can be set separately to act as a heating contact or a cooling contact. If set as a heating contact, the contact closes if the
actual temperature is less than the setpoint. For use as a cooling contact, the function is inverted. See also Figs. 1 - 4.
A3/A4 Function of regulation contacts 1/2 in the case of a sensor fault
Regulation contacts 1 and 2 switch to the position specified here in the case of a sensor fault. If a fault is detected in the parameter memory (display:
EP), which means that the saved settings cannot be used, regulation contacts 1 and 2 are switched to a state where no current flows.
A5 Operation with setpoint or DeltaW for regulation contact 2
This parameter determines whether the controller operates with two independently adjustable contacts (A5=0, operation with setpoint, factory
setting) or with two mutually linked contacts (A5=1, operation with Delta W).
This parameter always affects regulation contact 2.
A8 Display mode
The actual value can be displayed as an integer or with one digit after the decimal point (resolution 0.5 °C or 0.1 °C). If a resolution of 0.5 °C is
selected, the actual value is rounded up or down. All parameter settings and setpoints are always displayed with a resolution of 0.1 °C.
A9 Weighting factor
The actual value can be weighted with the aid of this parameter. The measured value is multiplied by this factor and the resulting value is displayed
and used for regulation.
A19 Parameter locking
With the setting A19=0, all parameters are accessible.
With the setting A19=1, all A parameters are locked except for A19 itself (factory setting).
With the setting A19=2, all A parameters and all P parameters are locked.
When parameters are locked, they cannot be changed with the buttons on the front panel. Any attempt to do this results in the message ”---" on the
display.
A30 Function of alarm output
The state of the alarm output depends on actual values with respect to the upper and lower limit values (see parameters P30 and P31). With this
parameter, you can select whether the alarm is activated when the actual temperature lies between the two limit values or when the temperature lies
outside the limit values. In the case of a sensor fault, the alarm is activated regardless of this setting. The output can also be inverted. See Figs. 5
to 8.
