dIP Switch Setting Modes of Operation (Mode) The Controller allows for eight modes of operation in (A) Factory / Installer order to define the Controller operation and piping arrangement used. The piping arrangement can be categorized into primary or primary/secondary. The The Factory / Installer DIP switch is used to select mode of operation is selected using the MODE item in which items are available to be viewed and / or adjust-... - Page 6 Two Setpoints with Primary/Secondary Piping Mode 2 (Mode = 2) Mode 2 is designed for setpoint operation using Primary/Secondary piping (see Fig. 9). A CFH is avail- able to activate a setpoint for space heating. An indirect DHW override is available to activate a second setpoint for heating an indirect domestic hot water tank.

During light loads, the dif- ferential is increased to allow longer on and off times to reduce the potential for short-cycling. During large loads, the differential is narrowed thereby improving comfort in heating spaces by reducing temperature swing.
