2.21.50 Control of additional heating stage — I-component (min)
Options: Setting option between 0 - 255
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.
Note
This parameter is only available when "Control value type" parameter for the
additional stage is set either on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or
"Fan coil". The "Additional heating type" parameter must be set on "Free
configuration".
Note
The following parameters are available when parameter "Controller function" is
set on "Cooling" and parameter "Control value type" on "2-point 1 bit, On/Off" or
"2-point 1 byte, 0/100%".
2.21.51 Cooling control — Cooling type
Options: PI continuous, 0 – 100% and PI PWM, On/Off:
■
Area (e.g. cooling ceiling) 5°C 240 min
■
Free configuration
Fan coil:
■
Fan coil 4°C 90 min
■
Free configuration
Two cooling types (area or fan coil) with preset parameters are available to the user.
If the required cooling type is not available, individual parameters can be specified in free
configuration.
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".
