Hey all,
Haven't posted for a while but come across a bit of a strange one on this job.
Outdoor to indoor unit wiring.
Outdoor is on 3ph, with 4 core to indoor unit, terminals 1,2,3,E. The units are literally powering up to full fan mode on the indoor and there is no activity on outdoor at all, apart from HAP blinking healthily and Red off.
Now, on inspecting the wiring, it goes:(outdoor to indoor)
1-1
2-2
3-condensate pump-return to 3.
As far as I am aware, terminal 3 is a data bearer as is 2, so could that be causing the units to be fan only? Irony is that there is no condensate for it to shift away :confused:
Just doesn't seem to make any sense!
Cheers as always :cool:
