21.3 Using the leak detection function
21.3.1 About automatic leak detection
The (automatic) leak detection function is not by default activated and can only
start working when the additional refrigerant charge is inputted into the system's
logic (see [2‑14]).
The leak detection operation can be automated. By changing parameter [2‑88] to
chosen value, the interval time or the time until the next automatic leak detection
operation can be chosen. The parameter [2‑88] defines whether the leak detection
operation is executed one time (within [2‑65] days) or intermittent, respecting an
interval of [2‑65] days.
Availability of the leak detection function feature requires input of the additional
refrigerant charge amount immediately after finishing the charging. The input must
be executed before performing the test operation.
NOTICE
If a wrong value is input for the additional charged refrigerant weight, the accuracy
of the leak detection function will decrease.
INFORMATION
▪
The weighed and already recorded amount of additional refrigerant charge (not
the total amount of refrigerant present in the system) must be entered.
▪
When the height difference between indoor units is ≥50/40 m, the leak detection
function can not be used.
