Other Contacts
Aux(iliary) Contacts: The auxiliary contact set is dry, meaning no supply of power is present at the terminal. The
maximum allowable load is 10A. The auxiliary dry contact is for switching another device (ie. the heat source)
when there is a call for heat.
Flow Sw(itch) Contacts: The wiring harness of the optional Flow Switch for DHW Priority (FLWSWITCH) uses these
contacts (see page 14).
