7. WIRING THE THERMOSTAT (Cont.)
c) Check each wire to ensure it is securely fastened, not broken, and exposed wires
are not touching.
8. REASSEMBLE THE THERMOSTAT
No tools required – line up pins on circuit board with the corresponding terminal blocks.
Use your hands to push the front panel securely to the mounted base.
CAUTION: Loss of internal programs may result from static discharge to thermostat circuit
board. Installer must touch a grounded metal object before handling the circuit board.
9. HVAC SYSTEM CHECK OUT
HVAC installer may need to connect 24V AC to the R and C terminals to check HVAC
operation. If the automation system is to be installed after the HVAC installation, leave the
R and C terminals connected to ensure the HVAC system operates. If the automation system
is installed before the HVAC wiring, then do not connect HVAC wires to R and C.
When the thermostat is first turned on all of the graphics of the main LCD are momentarily
displayed; this will look like Figure 6.
