Hi! First time poster here and I could really use some help.
I just replaced a non-programmable digital thermostat with a new Honeywell RTH-6450 5-1-1 programmable stat. Installation was a breeze and my air conditioner is working perfectly. However, I'm confused as to how to set up the advanced settings for my heating system.
I live in a condo building and checked with the original HVAC installer, who informed me that I have a two-stage heating system with perimeter radiant heat/forced air. As far as I recall, it's always worked where the radiant heat comes on first and then, rarely, the forced air engages if necessary. The installer told me to set everything up for electric in the advanced settings, which I did. I also made sure to enter the setting for single-stage air/two-stage heating (I checked and I do have both W and W2 wires hooked up for heat). However, when I tested the heat by knocking the temp up two degrees from the room temp, the blower came on immediately. As I said, I don't believe the blower is supposed to come on right away.
My advanced settings are as follows:
Function 1: "System type"
I entered #7 - "Heat/Cool Multiple Stages: Two heat stages (wires on W and W2), one cooling stage (wire on Y)"
Function 3: "Heating fan control"
I entered #2 - "Electric heat"
Function 5: "Heating cycle rate"
I entered #2 - "Electric furnace"
Function 6: "Stage 2 Heat cycle rate"
I entered #9 - "Electric furnace"
What did I do wrong? I even tried switching Function 5 to #3 - "Hot water or high efficiency furnace", thinking that this might work since the radiant heat uses hot water pumped through a pipe in the floor, but nothing changed.
