11.8.55 Additional cooling stage

Note
Only available when the "Extended settings" parameter under "Control of
additional cooling stage" is set on "Yes".
11.8.56 Additional cooling stage — Mode of the control value
Options:
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".
11.8.57 Additional cooling stage — Hysteresis (x 0.1°C)
Options:
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%".
11.8.58 Additional cooling stage — Control value difference for sending of cooling control
value
Options:
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".
