Installation Instructions
CAUTION
19. Gently tug each wire to be sure of proper
connection. Verfiy that each wire is connected to
the proper terminal.
20. Now we will set our dip switches located on the
rear of the wall thermostat. For Heat Pump models
(beginning with GRHS), flip dip switch #1 to "ON".
Additionally, if your unit will not be connected to a
furnace, or you want to disable the furnace, flip dip
switch #4 to "ON". If you want your wall thermostat
to display ambient temperature instead of setpoint
temperature, flip dip switch #3 to "ON". If your RV
AC will not be connected to a furnace, or you want
to disable furnace functionality, flip dip switch #4 to
"ON".
21. Reattach the thermostat cover by aligning the cover
and snapping the bottom in place.
22. Turn on power to the system at the main service
panel.
23. Test thermostat operation as described in the
