Configuring the Heater

The MP Series heater utilizes DIP switches on the modulating controller to configure various options
available. The DIP switches are located under the modulating circuit board cover (See Figure 2.6), and
are labeled "Options" and "Address". These switches have to be configured correctly in order for the unit
to properly function.
