5-2. Number of connectable units
The table below summarizes the number of connectable units.
Unit type
Number of connectable units
Indoor units, independent OA processing units, LOSSNAY units, DIDO
controllers (PAC-YG66DCA), Air To Water (PWFY) units, Advanced
HVAC CONTROLLERs, HWHP (CAHV) units, AI controllers (PAC-
YG63MCA), PI controllers (PAC-YG60MCA) in each AE-200/AE-50
system
Up to 50 units (including the interlocked LOSSNAY
units)
*1*2*3*4
Indoor units, independent OA processing units, LOSSNAY units,
DIDO controllers (PAC-YG66DCA), Air To Water (PWFY) units,
HWHP (CAHV) units in a group
1–16 units
(Indoor units, independent OA processing units,
LOSSNAY units, DIDO controllers (PAC-YG66DCA),
Air To Water (PWFY) units, and HWHP (CAHV) units
cannot be combined in one group.)
Remote controllers in a group
0–2 units
System controllers in a group
0–4 units (Up to four remote and system controllers
combined can be assigned to each group.)
Advanced HVAC CONTROLLER in a group
0–1 unit

Indoor units that can be interlocked with each LOSSNAY unit
1–16 units
*1 The maximum number of controllable units varies, depending on the number of channels used for the DIDO controller. In a system with
connection to Advanced HVAC CONTROLLERs, the number of connectable units is 70 units when using the monitoring function on the
Maintenance Tool, and 60 units when not using the monitoring function on the Maintenance Tool.
*2 By connecting AE-50 controllers to an AE-200, up to 200 units can be controlled (when connecting three AE-50 controllers).
*3 Each contact of DIDO controller (PAC-YG66DCA) counts as one unit.
*4 Although up to 15 PI controllers (PAC-YG60MCA) can be set for each AE-200/AE-50, the number of PI controllers in a system with
connection to one or more AE-50 controllers must be 20 or less.
