Sanyo ecoi - problem
Hello All !
I bought a used Sanyo Ecoi VRF systems with one outdoor unit and 12 indoor units fitted with 12 wired controllers.
Before to install everything i powered the indoor units to check them electrical .
5 of the indoor units did not power and red led is blinking inside on the board .
The models of the indoor units are SPW-KR94GXH56B (8 units ) and SPW-KR124GXH56B (4 units)
All SPW-KR124GXH56B did not work + one SPW-KR94 . All with same problem with blinking red led.
The outdoor unit models is SPW-C1155DXH8 .
Anyone can suggest what can be the problem ?
Thanks in advance

Re: Sanyo ecoi - problem
Did you connect all of the indoor unit to the main unit when you tested them?

Re: Sanyo ecoi - problem
yep its it shows indoor pcb is powered and transmitting a signal- transformer hasnt 2 outputs 12 and 24v - best option is get them fitted quick to then test it properly
usually sanyo kit is ok, compressors are expensive- but you can disable a faulty pot
