A50: Minimum action time contact K1 ”On”
A51: Minimum action time contact K1 ”Off”
These parameters permit a delay in switching on/off the relay in order to reduce the switching
frequency. The adjusted time sets the entire minimum time period for a switching-on or switching-
off phase.
A54: Delay after “Power-on”
This parameter allows a switching-on delay of relays after switching-on the mains voltage. This
delay corresponds with the time set here.
A56: Alarm suppression after "Power-On"
This parameter allows a switching-on delay of the alarm contact after switching on the mains
voltage or setpoint change-over. This delay corresponds with the time set here.
A60: Sensor type
These parameter permits selection of the sensor type, if the needed hardware prerequisites are
available.
A70: Software filter
With several measuring values, it is possible to obtain an average value. This parameter can
determine by how many measured values an average value is to be formed. If a sensor with a very
fast reaction to external influences is used, an average value ensures a calm signal process.
A80: Temperature scale
Indication can be switched between Fahrenheit and Celsius. At conversion, the parameters and
setpoints maintain their numerical value and adjustment range. (Example: A controller with the
desired value of 0°C is switched to Fahrenheit. The new desired value is then interpreted as 0°F,
which corresponds to a temperature of -18°C).
NOTE: Indication limits with °F can be smaller than the actual measuring range!
A85 Function key A
A86 Function key B
0: no function
1: actual value will be indicated if A32=1, otherwise no function
2: Setpoint S1 is switched to setpoint S1’ (see A33)
A87: Function standby key
The following functions are available:
0: the respective key has no function
1: the controller is switched to standby mode
A88: Delay for Standby ON
A89: Delay for Standby OFF
For switching the controller on and off, a delay for the Standby key can be defined here.
