Amerec 3224-022

This 3224-022 board replaces both the 3221-xxx and 3223-xxx boards. It is compatible with any controls or room temperature sensor that were connected to previous versions. Some versions had only four of the large black relays instead of six. The 3224-022 will work with those as well, just leave no connections on the back set of relays labeled K5 and K6.

NOTE: To preserve the originality, operation and safety of replacement parts, this product is not returnable.
