Hey guys, I have an existing honeywell R7184B 1032 primary control on my furnace. I have found a 7184b 1024 and a 1026 but no 1032 for a replacement. Does anyone now the difference? they both are 15 sec. it looks like the 1024 and 1026 have an extra set of terminals where the t stat connects. maybe for another t stat or alarm?
