(1) Switch names and functions
There are four main ways to set the settings as follows:
Dip switches (SW1 - SW3)
Dip switches used in combination with the push switches
Rotary switches
Slide switches
See below for how these switches are used to set certain items.
Different types of switches on the PCB

The action that the switch takes when set to a certain position depends
on the type of system configuration (e.g., individual or multiple system) REMOTE REMOTE
Slide switch (SWS2) Unused AA
Push switch (SWP1)
Switches the display between the item code and the current value for a specific item.
Increases value.
--
Push switch (SWP2)
Switches the display between the item code and the current value for a specific item.
Decreases value.
--
Push switch (SWP3)
Advances the item code.
Saves the changed value.
--
Dip switches (SW1-3) Switches the LED display contents.
