I bypassed the thermostat and the heater kicked on. I purchased a Honeywell programmable model RTH2300/RTH221 for replacement. Not sure of the wiring. I am going to storage to match wiring diagram of stock unit (2 wires) with new unit (multiple terminals). Has anyone done this type of replacement and can help? Thanks
