Honeywell Smart Thermostat for Home - WiFi Programmable Thermostat with Energy Saving Mode | Perfect for Smart Home Automation & Remote Temperature Control

I ordered this Honeywell Universal Replacement HSI control board to replace a York 031-01234-000 control board.The Honeywell circuit board comes mounted to a supporting plastic base, as opposed having only stand-off posts. The plastic base covers the entire copper side of the board (a nice touch!) so it was of no concern the board was not packaged in hard Styrofoam partitioning. The circuit board was packaged in an anti-static foam bag. The shipping box included a clear plastic bag of connection adapter wiring harnesses and a folded-sheets installation manual. The harnesses bag was inserted in to the box first, with the wrapped circuit board assembly placed on top. Placement in that order protected the component-side (top) of the circuit board from the Molex connectors of the adapter harnesses.The folded-sheets manual includes the fixed and variable parameters of the universal control board, a reference list of all the control boards that may be replaced with this board and the recommended switch settings (the board includes slide-switches) to closely match parameters of the replaced boards. The available settings might not exactly match those on your original board but the small variances should be acceptable, i.e.; 6 seconds flame-detect time as opposed to 7 seconds, etc.The board assembly included all the required connections (spade lugs for blower motor, electronic air cleaner, humidifier, transformer and line) necessary to replace the original board and provide the same functionality. Two sheet-metal screws are also included. The board is smaller than the original York and it was necessary to drill two mounting holes on the chassis shroud in the blower compartment (where the original board was located). This particular installation required that I use an adapter cable to connect the combination inducer motor / hot surface igniter 4-pin furnace-side connector to the replacement board. The 12-pin furnace-side connector was a direct plug-in to connector on the board. I was able to connect all remaining spade-lugged wiring without issue. The board includes 5 neutral connection spade lugs.I drilled the two holes and installed the board and wiring in fifteen minutes. At first power-up the green communication LED on the board flashed in data-transfer fashion as the CPU executed self-diagnostics and read the slide-switch settings (which I set to match the recommended settings in the manual). After the flashing completed I powered off the furnace, waited 15 seconds then powered it on to a HEAT call. The board functioned perfectly in sequence: inducer motor, hsi, gas valve, flame-detect, blower motor. After a few days we needed to set for COOL call (warmer days!) and that also functioned perfectly: a/c compressor contactor, blower motor. The fixed and recommended parameters set on this board seem to work better with our York / LuxAire PBKM series furnace than those set on the original board. I highly recommend this board for adequate installation manual, harness-wiring adapters and mounting screws inclusion, ease of installation and replacement value (was on sale: $104)!
