I am currently working on a 2 heat 1 cool system that has a single speed air handler. What I am trying to accomplish is to have the zone of baseboard on W1 or first stage heat, and the air handler on second stage heat. The issue is that the tstat energizes R-G and turns the blower on whenever there is a call for heat. So now I think, why not install an aquastat set to 140, that will hold off the blower until the second stage zone valve opens. This would hold the blower off until the second stage calls on. BUT, now how do I deal with turning on the fan during the cooling season ? There is only on Red wire with a jumper between RC and RH. Is there a way that I could wire in a RIB relay or something to bypass the aqaustat ?
