The Steffes Time Clock Module is an option for providing a peak control signal to the heating system. It mounts inside the system’s low voltage electrical compartment and interfaces with the relay expansion board via an interface cable. Peak control times must be programmed into the system once the module is installed to enable the time clock feature.
