WARNING: DO NOT SHORT (JUMPER) ACROSS TERMINALS OF
GAS VALVE OR SYSTEM CONTROL TO TEST OPER-
ATION. THIS WILL DAMAGE THE THERMOSTAT

CAUTION: DO NOT SWITCH SYSTEM TO COOL IF THE TEMPERATURE IS

ING SYSTEM AND CAUSE PERSONAL INJURY.
1. Place the AUTO-HEAT-OFF-COOL switch into
the COOL position.
2. Press the ٚ button until the temperature setting
is at least 3 degrees below the room temperature.
The air conditioning system should turn on within
a few seconds.
NOTE: ONCE THE THERMOSTAT TURNS OFF WHEN IN THE COOL MODE, A
BUILT IN 5-MINUTE DELAY PREVENTS THE SYSTEM FROM TURN-
ING ON AGAIN. THIS PROTECTS THE COMPRESSOR. NO ADDI-
TIONAL TIME DELAY RELAY IS REQUIRED. TO OVERRIDE THE 5-
MINUTE DELAY FOR INSTALLATION, PRESS THE RESET BUTTON.
