    Honewell RTH230B installation
    I purchased a Honeywell Thermostat (RTH230B) to replace a Janitrol HPT 18-60. The Janitrol has 7 wires hooked to the back and the Honeywell only has 5 places for wires. Is my Honeywell compatible? Thanks

    If your Janitrol is a heat pump it is not compatible. No multistage heating.
