A50 Minimum "On" time, regulation contact 1
A51 Minimum "Off" time, regulation contact 1
A52 Minimum "On" time, regulation contact 2
A53 Minimum "Off" time, regulation contact 2
These parameters make it possible to ensure that the output contact remains on or off for a specified time in order to reduce the switching frequency.
The time specified here is the total minimum time for the on or off state of the contact (factory setting: 0 s).
A54 Delay after power on
With this parameter, activation of regulation contacts 1 and 2 can be delayed by a specified period after the mains voltage is switched on.
A55 Mutual delay, regulation contacts 1 and 2
This parameter permits the activation of regulation contact 1 to be delayed by a specified period with respect to activation of regulation contact 2 or
vice versa, depending on which contact is activated first.
A56 Alarm suppression after power on
This parameter permits the activation of the alarm contact to be delayed by a specified period after the mains voltage is switched on (factory setting:
20 minutes).
A60 Temperature sensor
This parameter permits selection of the type of PT100 temperature sensor connection (factory setting: three-wire connection).
A70 Software filter
The measured value is averaged over the number of measuring cycles specified here. This average value is displayed and used for regulation. A70=1
deactivates the software filter.
A80 Temperature scale
The temperatures can be displayed in Fahrenheit or Celsius (factory setting). Note that the values and setting ranges for the parameters and setpoints
remain unchanged when the scale is changed. If, for example, a controller whose setpoint is set to 0°C is modified to display the temperatures in
Fahrenheit, the setpoint is then interpreted as 0 °F, corresponding to a temperature of -32° C.
In addition, you can specify whether the controller displays the word AUS (German) or OFF (English) when it is in standby mode.

(A92 No connection)
Depending on the hardware, the relays can be connected to various signals from the regulator:
Regulator outputs
Regulation contact 1 Regulation circuit set with the parameters S1, P2, A1
Regulation contact 2 Regulation circuit set with the parameters P1, P3, A2
Alarm
Alarm circuit set with the parameters P30, P31, P32, A30
Buzzer function
As for internal horn, intermittent, can be acknowledged with the DOWN button (affected by parameter A31)
