1 Water only at the base of the plant and early in the day. Long periods of moisture on foliage encourage blight.  Use a tomato staking system and remove suckers to increase air movement through the plant and to reduce moisture on the foliage. Staking also improves fruit quality and helps prevent root rot.

It has 2 plugs that plug into it. That is the entire controlling aspect of the blower operation with an automatic climate control system. There are no other relays.
ECM blower motor replacement. I'm thinking about replacing the standard PSC induction blower motor in my gas furnace with one of the newer ECM replacement motors such as the Emerson 5540ET. The electric savings would be nice, but the primary reason I want to do it is to eliminate the hum that the current motor generates when it starts.
