Hi,
I've discovered a problem at one of my installation site. The comfort outputs are wired to relays (omron G2R-1S-DC12S rated coil at 43.2mA). These relays are then (the NO terminal) connected to Aircond Contactors (AC240VAC) so that we could achieve of controlling the aircond power. I've also add diodes (4001) to "+" and '-" on the omron relays.
The problem is whenever we try to switch the 2 or more outputs ON when all these are connected, the comfort outputs will reset and went to the OFF state. But if the AC contactors are removed, the problem will dissapear.
FYI, I am using Comfort version 5.075 File System 34 UCM 5.079 type 10.
Is there any tricks to avoid this??
