Checking Dipswitches on DXM2

Use a magnet to pull the internal slide to one side or another.
Verify that dipswitch number 1
is in the ‘On’ position.
If dipswitch number 1 is in the
‘Off’ position, the thermostat
will not function.
Under most residential
situations, dipswitch banks
1 and 2 will all be in the ‘On’
position.
If any of these dipswitches
need to be switched to ‘Off’,
consult the DXM2 AOM
(97B0003N15).
