    Question ICM222 vs ICM221 Anyone Use These?

    I was looking over the ICM 222 lockout board and thinking of putting it in some near-death, huge Lennox circa 1989 units. Anyone out there use it and like it? Is the ICM 221 a better choice?

    Ive been using ICM controls and really like them. I bought a few ICM 151 controls for old water source heat pumps. They seem smaller then what you posted and have a selectable delay on make timer as well and the lock out function. I would check that one out as well.
    Plus they are Made in USA.

    Thanks for the tip. I will check that one out as no one around here seems to carry the ICM222
