– Normal: Value 0 means "Valve closed".
– Inverse: Value 0 means "Valve open".
12.34.48 Basic stage cooling – Hysteresis (x 0.1 °C)
Options
Note: This parameter is 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".
12.34.49 Basic stage cooling – Control value difference for sending of cooling control
value
Options
Note: This parameter is 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.
12.34.50 Basic stage cooling – Cyclic sending of the control value (min)
Options
Note: This parameter is only available when "Control value type" parameter is
set either on "PI continuous, 0 – 100%", "PI PWM, On/Off" or "Fan coil".
The current control value used by the device can be cyclically transmit to the bus.
