Title: Newbie needs help, (in soooo many ways), thermostat control
Post by: Sawdust on July 24, 2010, 06:30:34 AM

 Hello, I am considering purchasing a Woodmaster 4400, that being said, I am in need of how to wire a thermostat so as to control the existing HVAC blowerfan. I have an older modle Lennox HVAC system including inside back-up electric coil. My problem is , the old lennox wiring uses different color code, or the installer did'nt follow standard color wiring. I would appreciate any help. If I go to the blower and backtrack the wiring to the first relay or contactor, could I splice-in some sort of diodes or isolation relay, so that the blower could be controlled from a second thermostat? Thanks for any info . Sawdust
