thermostat control fan
 
I installed a Taylor waterstove and now have two heat sources.I am trying to stop using gas.I am trying to make my thermostat only control the blower and not the gas part of the furnace. I disconected the W wire from the furnace and the thermostat.The thermostat called for heat and nothing happened.Perfect.Then I added a jumper wire from the W to the G set the themostst to call for heat went under the house depressed the door switch it worked perfect until I replaced the door and upon crawling out from under the house realized the airconditioner was also on. Why? Is the solution complicated?Is there power feeding through the ground?

Your going to need a relay, when your energizing G its somehow energizing Y also, the problem is probably in the T-stat...
