SMARTZONE ECONOMIZER OPERATION
WHEN THE Y TERMINAL ON ZONE 4 IS ENERGIZED BY AN OUTDOOR SENSOR, A COOLING CALL FROM ANY OTHER THERMOSTAT (ZONE
1 –3) WILL ACTIVATE ECONOMIZER MODE.
1. FRESH AIR DAMPER (Z-4) WILL OPEN
2. EQUIPMENT FAN (G) WILL ENERGIZE
3. ZONE DAMPERS CALLING FOR COOLING WILL OPEN
4. EQUIPMENT COMPRESSOR (Y1) WILL NOT ENERGIZE INITIALLY
5. IF THE SUPPLY TEMPERATURE DROPS BELOW THE LOW TEMP LIMIT**, THE FRESH AIR DAMPER WILL CLOSE BUT G WILL
CONTINUE TO RUN UNTIL THE SUPPLY TEMPERATURE RISES BACK ABOVE LOW TEMP LIMIT
6. ECONOMIZER MODE WILL STOP (FA DAMPER CLOSES) AND NORMAL COOLING (Y1) WILL START IF THE SUPPLY TEMPERATURE
RISES ABOVE THE ECONOMIZER HI TEMP LIMIT FOR 3 MINUTES. (SEE RIGHT TO SET THE ECONOMIZER HI TEMP LIMIT)
ECONOMIZER HI TEMP SETTING

2. HOLD THE DOWN ▼BUTTON FOR 6 SECONDS AND RELEASE
3. “ECO AND HI TEMP” SHOULD FLASH ON THE DISPLAY, THEN
USE THE ▲▼BUTTONS TO SET
(DEFAULT = 60, RANGE = 58 –68)
