Configurable digital input can be activated via signal triggered by push button, presence detector or any other external
device with digital output, such as Building Management Systems (BMS)
Configurable digital inputs are grouped in levels of priority, Configurable Digital Input 1 being the highest,
meaning it can’t be overwritten by other user functions.
5.5.1.4 Digital input and Mode hierarchy
User modes and functions have a different hierarchy. User functions activated via HMI or mobile APP, such as AWAY,
CROWDED,FIREPLACE,HOLIDAY and REFRESH, are interrupted by manual selection of AUTO and MANUAL fan modes.
AFIREPLACE function has the highest priority between user functions. Other functions activated via HMI/APP can in-
terrupt each other.
If FIREPLACE function is hard-wired on the connection board and configured as digital input (DI) then it has a higher
priority than AUTO and MANUAL mode. Digital input for a FIREPLACE function has also a higher priority than other
hard-wired digital inputs (DI) for: AWAY,CENTRAL VACUUM CLEANER,COOKER HOOD,CROWDED,HOLIDAY or REFRESH.
Fig. 2 Hierarchy of user modes and digital inputs
Modes are listed from the highest to lowest priority; A — user modes that can be activated from the control panel; B —
user modes and functions activated via digital input
