'emergency' operation on Daikin VRV
Good evening gents,
Been working on an old R22 'K' series VRV.
model: RSEY10KJW1.
Having problems with the inverter side of unit; inverter comp seized.
So, I've set the 'emergency' switch to on at the main pcb. Set all 7 fan coils to heat and ramped the temperatures up to 32.
Unfortunately the VRV does not want to run. No fault codes showing on R/C's.
I powered down the VRV prior to using the emergency switch.
As far as I know, this should be the only adjustment required to operate the VRV on standard comp.
Any other ideas?
regards,
Jase
