IO Setup If the digital inputs have the same function allocation (also applies for timer function)
you can choose between an AND and OR operation.
OR operation (factory setting). The function becomes active when one of the digital
inputs or the timer is activated.
AND operation. The function becomes active when all digital inputs or also the timer
are activated.

Function Description
OFF
no function (factory setting)
Enable
(1D)
Enable (remote control) “ ON ” / “ OFF ”
External error
(2D)
External alarm indication
Limit
(3D)
“ Limit ” ON / OFF
In fl uences control circuit 1 and control circuit 2 in operation with two control circuits
E1 / E2
(4D)
Switch over input “ E1 ” / “ E2 ” (for operation with one control circuit)
Reset
(10D)
Complete re-start of the device
Max. Speed
(11D)
Setting Max. Speed “ ON ” / “ OFF ”
In fl uences the respectively set value “ 1. Max. Speed ” and “ 2. Max. Speed ” in operation
with two control circuits.
Override Time
(21D)
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 1.01
Setpoint1/2
(5D)
Switch over “ Set Intern1 ” / “ Set Intern2 ”
“ Setting External 1 ” must be at “ OFF ” .
Setpoint int./ext.
(6D)
Switch over “ Intern ” / “ Extern ”
For modes as controller (from 2.01. )
Setpoint1/2
(5D)
Switch over “ Setpoint 1 ” / “ Setpoint 2 ” for control circuit1
Setpoint int./ext.
(6D)
Switch over “ Intern ” / “ Extern ”
Possible only for operation with one control circuit!
Control/Manual
(7D)
Switch over “ automatic control ” / “ Speed manual ”
Possible only for operation with one control circuit!
Heating/Cooling
(8D)
Switch over control function (e.g.
“
heating
”
/
“
cooling
”
)
1.Setp+Pband1/2
(15D)
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
E1 / E2
(4D)
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.
2. Setpoint 1/2
(9D)
for control circuit 2: Switch over “ 2. Setpoint 1 ” / “ 2. Setpoint 2 ”
2.Setp+Pband1/2
(16D)
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
for control circuit 2 ”
