9.26 P robe error management
The k.Air controller software features specifi c device management and/or control functions in the event of probe errors.
Normally, the device or function associated with a probe alarm is deactivated, so as to avoid control being based on inaccurate
values, however in some special cases the devices can be managed by setting a fi xed percentage, so as to allow the unit to
continue operating, albeit without guaranteeing optimal control.
There are two special cases:
1. fan control in the event of air quality/pressure probe error: the value can be set on screen Bb01 (supply fan) and Bc01 (return fan).
2. auxiliary control in the event of an error on the corresponding probe the value can be set on screen H02.

In addition, control probe errors are managed specifi cally, involving various devices. In this case, the following can be selected:
• shut the unit down (Off ), or switch off all of the devices after the corresponding delay times (post ventilation, damper closing
time, compressor times).
• set a fi xed percentage of operation for each device.
These values are available (if the function is enabled) on screens Ac70, Ac72, Ac74. In this case, all of the alarms still remain active.
It is also possible to enable this function even when the unit is Off , in which case only the water coils are forced to the set per-
centage for frost protection, as otherwise this cannot be correctly controlled. This function has priority over any other special
functions.
