A40: Hysteresis mode contact K1
A41: Hysteresis mode contact K2
These parameters allow selection as to whether the hysteresis values which are adjustable with
P2, P3 are set symmetrically or one-sided at the respective switching point. At symmetrical
hysteresis, half of the hysteresis’ value is effective below and half of the value above the switching
point. The one-sided hysteresis works downward with heating contact and upward with cooling
contact (see fig. 1 + 2).
A51: Minimum action time K1 “off”
These parameters permit a delay in switching on the relay in order to reduce the switching
frequency. The adjusted time sets the entire minimum time period for a switching-off
phase.
A56: Alarm suppression after ”mains-On” and/or "Standby-On"
This parameter allows a switching-on delay of the alarm contact after switching on the mains
voltage or standby. 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 course.
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: Reset mode of fat operation time
To force the exchange of used fat, a reset of the fat operation time is only possible in case of an
alarm message or regulation blocking together with the cool-off according to parameter P29.
If the fat exchange is secured otherwise an unconditional reset can be enabled with this parameter.
A86: Key delay for Standby key
This parameter is to activate a delay time for the On/Off key. Please note the 0.1 seconds scale.
A87: Standby function with Start/Stop key
The standby function can be disabled.
A88: Reduced heating
With this parameter the “reduced heating” mode can be enabled.
A89: Initial setpoint selection after mains on and/or standby
