Setting Max. Speed "ON" / "OFF"
Influences the respectively set value "1. Max. Speed" and "2. Max. Speed" in operation
with two control circuits.

"Freeze function" = maintain momentary modulation value
Overwrite timer function (in operation with timer)
The timer output is overwritten for a settable time with a selectable status (ON / OFF).

For Mode Speed controller
Switch over "Set Intern1" / "Set Intern2"
"Setting External 1" must be at "OFF".
Switch over "Intern" / "Extern"

Switch over "Setpoint 1" / "Setpoint 2"for control circuit1
Switch over "Intern" / "Extern"
Possible only for operation with one control circuit!
Switch over "automatic control" / "Speed manual"
Possible only for operation with one control circuit!
Switch over control function (e.g. "heating" / "cooling")
for control circuit 1: Switch over Setpoint 1/2 and Pband 1/1
When programming this function, "Setting" additionally lists the parameter: "1.Pband 1.
for control circuit 1"
Only active in operation with a second control circuit
The output for control circuit 2 is set additionally to "A2" to "A1" (regardless of the
programmed function for "A1"). Control circuit 1 has no output for the duration of the
switching.
The switch over input "E1" / "E2" as in operation with one control circuit is no longer
possible.
for control circuit 2: Switch over "2. Setpoint 1" / "2. Setpoint 2"
for control circuit 2: Switch over Setpoint 1/2 and Pband 1/2
When programming this function, "Setting" additionally lists the parameter: "2.Pband 2
