Not sure this is the correct place to post this!
I need help with the wiring of a HAI RC100B Omnistat in the RS232 mode to a
Lennox CBX32-10-P var speed air handler with 10kw heat strips(ECB29-10-P).
Lennox XP15-042 Condensor.
I had to replace my HVAC system and the old CAMSTAT t-stat will not handle the aux (heat strips).
A wiring dirgram would be most helpfull....
