Description Remedy
An address conflict has occurred. Ô A second control pan-
el with the same address is connected in the group. In
some cases a group can have 2 fan modules or 2 direct
evaporator modules (max. one module possible). Check
and change if necessary at the address selector switch (for
changes see "Setting Group Address" on page 25).
There are more than 16 controllers connected in a group.
➜ Check and, if necessary, correct the number of
connected units.
Error at the analog input X (X = 1 to 8) ➜ Check connection
of the sensor, possible cable break/short-circuit or missing,
even though the control (software) requires a sensor. For
further clearance of faults, see operation manual of global
modules.
NOTE
The relevant messages are connected with the designation of the relevant
faulty unit/module (location) and displayed. See chapter "Submenu: Operation
messages" on page 49.
