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 system..

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....

Thanks

Ed
