lem01-m2

[salizam]

 I have a comfort G2 (two main board, 1 digital w/i 1 analog) with the firmware \"'entry' 'greeting' 5.54 24.2\" . I just added a LEM01-M2 so that i can hv 16 zone and 16 output.

 My problem is that when I add the LEM01-M2 the comfort does see the 8 new zones, but it does not see the 8 new output 12vdc. However when I unplug the Ribbon cable  connector to the LEM01-M2 the comfort complains saying \"Zone 9, 10 and so on up to 16.. Trouble….. etc\" . This indicates that the comfort is aware that the  zones exist but is not seeing the output.

Pls help.

thanks

Are you saying that there is no 12V present on the outputs even before you attempt to control them? If so, is your OP1 Board sitting properly on the LEM01-M2?

I checked the OP1, its seated properly and firmed on the socket. Infact i also try to interchange the one on the LEM01-M2 with the one on the main board. And the result is the same, no respond.

How do you test that there is no output? are you using a real load or are you measuring the voltages?
