Below (Figure 3.6) is the SRD notifications system communication diagram. A website will monitor a few SRD. This website
will be monitored and accessed by the Daikin BMS Servicing department. Should the alarm notification be sent out, then
technicians will be mobilised immediately.

Currently, all the existing R410A multi-split air conditioning
system uses a single port to measure low-pressure refrigerant
pressure, as shown in Fig. 4.1. All the latest R32 multi-split air
conditioning system model comes with multiple low-pressure
ports. The servicing team faces the problem of measuring
the refrigerant pressure - a single manifold gauge is unable
to measure multiple low-side ports at the same time during a
refrigerant pressure check.
