9.10.2.11 Switch over Setpoint 1/2 for control circuit 2
|
9D
|
Switch over between “ 2.Setpoint 1 ” and “ 2.Setpoint 2 ” (for operation with two control circuits)
Contact e.g. at ditgital input “ Digital In 1 ” (depending on device type at terminals “ D1 ” - “ D1 ” or “ D1 ” -
“ 24 V ” ).

Info
Operation with “ 2. Setpoint2 ” is signalized by the moon symbol for reduced operation.
If Setpoint 2 was activated additionally for control circuit 1
“
1.Setpoint 2
”
by a digital
input with function

|
The value for “ Max Speed ” adjusted in menu “ Settings ” , is activated over a digital input. I.e. the unit
works independently of the controller function
fi
rm with this value.
Contact e.g. at ditgital input “ Digital In 1 ” (depending on device type at terminals “ D1 ” - “ D1 ” or “ D1 ” -
“ 24 V ” ).
This function in fl uences both circuits in operation with two control circuits.

9.10.2.13 Switch over Setpoint 1/2 and Pband 1/ 2 for control circuit 1
|
15D
|
Switching between “ 1st setpoint 1 ” / “ 1st setpoint 2 ” and “ 1st Pband 1 ” / “ 1st Pband 2 ” (from 2.01 , not
for 2.03 ).
Function basically the same as
|
5D
|
, it is additionally switched over to Pband 2.
When programming this function, “ Setting ” additionally lists the parameter: “ 1.Pband 1. for control
circuit 1 ”
Contact e.g. at ditgital input “ Digital In 1 ” (depending on device type at terminals “ D1 ” - “ D1 ” or “ D1 ” -
“ 24 V ” ).
Example for “ D1 Inverting ” = “ OFF ” :
•
With open contact:

”
= 5 K
•
With closed contact: “ 1.Setpoint 2 ” = 17 ° C + “ 1.Pband 2 ” = 3 K
