Electronic control box
The electronic control box is located at the return air
opening on the base of the AC and the DIP switches are
visible through the opening.
The DIP switches are set to the Off position (except for
the 120 ohm switch) when shipped from the factory.
Heat pump models will have the appropriate switch
selected in the On position. Placing the switch in the On
position selects that option.
8.3.2 Setting the DIP switches
This section describes the appropriate electronic
control box DIP switch settings. The position should be
set to the appropriate On or Off position based on the
equipment options installed by the RV manufacturer.

DIP switch setting configuration
DIP location Description
1 Zone 2
Each thermostat can have up to four
zones. If only one rooop component is
installed, it becomes zone 1 by default
and DIP switch settings for zones 2, 3, or
4 are not required.
If more than one rooop component is
installed, assign each rooop component
a separate zone (2 through4). Each
rooop component must have a different
zone setting.
2 Zone 3
3 Zone 4
4 Stage
For applications requiring two
rooop components to work together in
the same zone, set the Stage DIP switch
to the On position.
Otherwise, leave in the Off position.

If a Furnace/Hydronic heating
system has been connected to this
rooop component, set the Furnace DIP
switch to the On position.
Otherwise, leave in the Off position.
