Control of additional heating stage - P-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 is set either
on "PI continuous, 0 – 100%", "PI PWM, On/Off“ or "Fan coil". In addition, the
"Additional heating type" parameter must be set on "Free configuration".

11.3.26
Control of additional heating stage - Temperature difference to basic stage (x 0.1°C)
Options:
Setting option between 0 - 255
The setpoint temperature of the additional stage is defined as a function of the current setpoint
temperature of the base stage and is expressed as a difference. The value represents the
setpoint value starting at which the additional stage will operate.

11.3.27
Control of additional heating stage - Extended settings
Options:
No
Yes
This parameter enables additional functions and communication objects, e.g. "Additional
heating stage".

11.3.28
Additional heating stage
Note
Only available when the "Extended settings" parameter under "Control of
additional heating stage" is set on "Yes".

11.3.29
Additional heating 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.
– N
ormal
: Value 0 means "Valve closed".
–
Inverse
: Value 0 means "Valve open".
