6.2 Setpoint offset
The
can be adjusted in the RAM 712 via object 1
manual setpoint value
offset
.
In this case, the setpoint value is changed by sending the desired offset to object 1.
This involves the differential (may be preceded by a minus sign) being sent in EIS5 format
to object 1.
The differential between the setpoint value offset and the base setpoint value is sent by object 10
at each change (e.g. -1.00).
The offset limits are set on the
setpoint values
parameter page with the
maximum valid setpoint
offset
parameter.
The offset always relates to the
and not to the current setpoint value.
Example
Base setpoint value of 21°C:
If a value of 2.00 is sent to object 1, the new setpoint value is calculated as follows:
21 °C + 2.00K = 23.00°C.
To then bring the setpoint value to 22°C, the differential is resent to the programmed base
setpoint value (here 21°C), in this case 1.00K (21°C+1.00K=22°C)
