9.8.52 Control of additional cooling stage - Extended settings
Options:
No
Yes
- This parameter enables additional functions and communication objects, e.g. "Additional cooling stage".
9.8.53 Additional cooling stage
Note:
Only available when the "Extended settings" parameter under "Control of additional cooling stage" is set on "Yes".
9.8.54 Additional cooling stage - Mode of the control value
Options:
Normal
Inverse
The mode of the control value can be used to adapt the control value to de-energised opened (normal) or de-energised closed (inverse) valves.
-
Normal
: Value 0 means "Valve closed".
-
Inverse
: Value 0 means "Valve open".
9.8.55 Additional cooling Stage - Hysteresis (x 0.1°C)
Options:
Setting option between 3 - 255
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".
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%".
9.8.56 Additional cooling stage - Control value difference for sending of cooling control value
Options:
2 %
5 %
10 %
The control values of the 0 - 100% PI continuous controller are not transmitted after every calculation. Instead, they are transmitted 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.
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".
9.8.57 Additional cooling stage - Cyclic sending of the control value (min)
Options:
Setting option between 1 - 60 minutes
The current control value used by the device can be cyclically transmitted to the bus.
Note:
This parameter is only available when the "Control value type" parameter is set either on "2-point 1 Byte, 0/100%", "PI continuous, 0-100%" or "Fan coil".
9.8.58 Additional cooling stage - Maximum control value (0 - 255)
Options:
Setting option between 0 - 255
The maximum control value of the PI controller defines the maximum value outputted by the controller. If a maximum value under 255 is chosen, the value will
not be exceeded, even if the controller calculates a higher control value.
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".
