I've recently had XV90 with XR13 A/C installed in my house and wander if it set up correctly for Comfort-R. Installer set up deep switches on the control board for Comfort-R operation (5,6 - ON) but didn't put any jumpers between Y-0 or Y-R. I got single stage thermostat White-Rodgers 1F90-371, might upgrade to 2 stage stat (still debating). Was installer supposed to set jumpers for my configuration or not? It is a little early in the year to worry about A/C operation by I wanted to know ahead of time. I'll have A/C checked before the cooling season to ensure that it operates properly. Furnace appears to be working OK. It wasn't cold here in Ohio since the install. At 28-30 degrees outside furnace would come on for 10-12 min with 15 min off time. Is it normal?
