Function of Object 6
Function
Determine the maximum actuating
value
This object has 2 functions here:
1. Receives actuating values from the other
actuators (other rooms), in order to be able
to compare them with its own.
2. Sends its own actuating value to the heating
boiler, if it is higher than the others.
(See also: Determining maximum actuating
value)
Sends the actual valve position
Sends the current valve position (0..100%).
This function can be enabled (e.g. diagnosis) as and
when required.
This function is not required for normal operation.
• Object 7 "Current actuating value, heating"
This object is present only when selected on the "Heating control" page as follows.
The current actuating value (0…100%) can then be sent to other continuous actuators (Cheops
drive) in the same room/control circuit.
If you wish to read out Object 7 via the bus, Object 8 must not be present ("Used control
functions" on the "Settings" parameter page set to "Heating control only"). The
"Read" flag must be set.
If you wish to read out Object 8 via the bus, this parameter must be set to "Not present".
• Object 8 "actuating value cooling"/"Actuating value of additional heating"
The function of this object depends on the "Input for actual value" parameter on the "Settings"
parameter page.
