This DIP switch is used to match the utility’s signaling device to the Steffes microprocessor based heating equipment and the Steffes PLC Receiver(s) for peak control purposes.
Off = An open utility switch will signal an off-peak time to the heater (charging is enabled in the ETS heater). A closed utility switch will signal an on-peak time (charging is disabled in the ETS heater).
On = A closed utility switch will signal an off-peak time to the heater (charging is enabled in the ETS heater). An open utility switch will signal an on-peak time (charging is disabled in the ETS heater).
NOTE: The peak control signal is a priority signal. When the room heating units or mini receiver controlled devices are receiving a peak signal, an anticipated peak signal will be overridden.
