Description
The Weil McLain 640-000-003 Control Module Assembly is a electronic operator unit used to regulate and coordinate the work of heating elements in HVAC systems. It is installed in the control compartment of the equipment and uses ABM08, and it takes input signals from thermostats, sensors and safety tool to program operations like ignition, activation of the blower motor and safety shutdowns. The understanding of signals, and the transmission of relevant commands are also assisted by the module to make sure that the heating appliance works in the right sequence, and reacts to the temperature needs.
