KNX communication objects
LVLØ controller is cyclically sending water condition values to the bus so these can be used in KNX
visualization. Water treatment hardware can be also monitored via KNX. It is possible to:
Display actual pH, Redox or free chlorine values.
Monitor conditions of water in pool and alert in case of issues with pH and redox parameters.
Monitor chemical stock alerts.
Monitor sensors status and alert in case of damaged or problematic probes, etc.
Monitor next service intervals for installed probes.
Change interval for cyclical sending of actual water condition communication object to KNX bus.

Backwash valve
3.11.1
Overview
Regular and correct backwash process of pool filter system is vital for ensuring crystal clear water. To always
get flawless results, LVLØ can directly control the backwash process in swimming pool. You can choose
between multi-port (6-way valve) and push-pull valve (e.g. Besgo). Possible 6-way valve positions are:
Filter - runs pool water from pump through the sand filter and back into the pool. This position is used most
of the time.
