12.34.61 Additional cooling stage– Hysteresis (x 0.1 °C)
Options
Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the control function parameter is set on either
"Cooling with additional stage" or "Heating and cooling with additional stages", only
available when the "Control value type" parameter is set either on "2-point 1 Bit, Off/On"
or "2-point 1 Byte, 0/100%".
The hysteresis of the two-point controller specifies the fluctuation range of the controller
around the setpoint value. The lower switching point is located at "Setpoint value minus
hysteresis" and the upper point is at "Setpoint value plus hysteresis".
12.34.62 Additional cooling stage – Control value difference for sending of cooling
control value
Options
Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the control function parameter is set on either
"Cooling with additional stage" or "Heating and cooling with additional stages", only
available when "Control value type" parameter is set either on "PI continuous, 0 – 100%"
or "Fan coil".
The control values of the 0 - 100% PI continuous controller are not transmitted after every
calculation. Instead, they are transmitting when the calculation results in a value that is
different enough to the previous sent value to make a transmission meaningful. This value
difference can be entered here.
12.34.63 Additional cooling stage – Cyclic sending of the control value (min)
Options
Note: Only available when the "Device function" parameter is set on either
"Single device" or "Master device" and the control function parameter is set on either
"Cooling with additional stage" or "Heating and cooling with additional stages", only
