thermostat. Gently pull the control panel
straight off the base. Forcing or prying on the
thermostat will cause damage to the unit.

power supply module using appropriate
wiring schematic. See figure 4
3. Using two mounting screws mount the power
base to the wall. Place a level against bottom
of base, adjust until level, and then tighten
screws. (Leveling is for appearance only and
will not affect thermostat operation.)
