12.34.44 Control cooling – I-component (min)
Options
Input from 0 to
255
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". In addition, the
"Cooling type" parameter must be set on "Free configuration".
The I-component refers to the reset time of a control. The integral component has the
effect of moving the room temperature slowly toward, and ultimately reaching, the setpoint
value. Depending on the type of system used, the reset time has to have different values.
In general, the more inactive the overall system, the greater the reset time.
12.34.45 Control cooling – Extended setting
Options No
Yes
This parameter enables additional functions and communication objects, e.g. "Basic
stage cooling".
12.34.46 Basic stage cooling – Cooling status object
Options No
Yes
Note: Only available when the "Extended settings" parameter under "Cooling
control" is set on "Yes".
This parameter enables the “Status cooling” communication objects.
12.34.47 Basic stage cooling – Control direction of control valve
Options Normal
Inverse
Note: Only available when the "Extended settings" parameter under "Cooling
control" is set on "Yes".
The mode of the control value can be used to adapt the control value to de-energized
opened (normal) or de-energized closed (inverse) valves.
