Description
The York S1-031-03757-000 is a circuit board, a special control part for the two-stage defrosting HVAC equipment. This circuit board plays a essentialrole in supervising the defrost cycle of heat pumps and air conditioners for proper performance in cold climates. In this case, controlling the time and sequence of the defrost operation assists in keeping a check on the ice building on the evaporator coils which in turn hampers heat transfer and reduces the efficiency of the system. In addition, the 2-stage functionality allows for more accurate control, and therefore energy consumption will be more efficient as well as the full functionality of the product.
