NOTES:
1. IF ANY OF THE ORIGINAL WIRING AS SUPPLIED WITH THIS FURNACE MUST BE REPLACED, IT MUST BE WITH WIRE
HAVING A TEMPERATURE RATING OF AT LEAST 105ºC. WIRES 12, 48, 49, 50, & 51 ARE RATED 250°C.
2. FOR PROPER AIRFLOW IN COOLING/HEAT PUMP MODE, "Y1" MUST BE CONNECTED TO THE THERMOSTAT.
3. USE "Y1" FOR THE CONNECTION TO THE LOW-VOLTAGE TERMINAL BLOCK.
4. THE INDOOR BLOWER MOTOR AIRFLOW TABLES ARE LOCATED IN THE SERVICE FACTS. TO
CHANGE AIRFLOW USE THE MENU/OPTIONS BUTTONS.
5. LINE CHOKE AND WIRE BK/28 ONLY USED ON MODELS WITH 3/4 AND 1 HP MOTORS.
6. FLAME SENSE TEST PADS: 1 VDC = 1 MICROAMP. FLAME CURRENT
CAN VARY DEPENDING ON THE VOM THAT IS USED
AND THE VOLTAGE SUPPLIED TO
THE FURNACE. THE ACCEPTABLE
RANGE IS 0.75-3 MICROAMPS.
