▪ Example: Remote controller is set to Cooling and temperature is set to 19°C. R5T
(discharge temperature) is 19°C but we expect that air will reach the room at
21°C due to heat losses in the ducting. In this case, you MUST use of correction
factor 21-13=5 [it means CF=2]. Then the unit tries to achieve R5T = 17°C which
will result to target temperature = 19°C.

F1/F2 wiring should ONLY be connected to EKVDX-A in case of EKVDX-A/VAM pair.
Upon communication initialization of F1/F2 communication circuit via VRV outdoor
unit, if EKVDX-A is detected alone (due to installation mistake or issues at P1/P2
wiring between EKVDX-A and VAM etc) then UJ-35 error will be triggered. If F1/F2
is connected to VAM as well, then UJ-36 error will be triggered.
BRC1H52/82* is the dedicated remote controller for R32 units. In case of VRV R32
and BRC1H51/81 is used, U5-04 error will be triggered. No more than 1 pair of
EKVDX-A/VAM CAN be connected through P1/P2 wiring. EKVDX-A/VAM is ALSO
