D (LIT) 1. IF ANY OF THE ORIGINAL EQUIPMENT WIRE IS REPLACED USE WIRE RATED FOR 105°C. 2. INDUCER (IDM) AND BLOWER (BLWM) MOTORS CONTAIN INTERNAL AUTO-RESET THERMAL OVERLOAD SWITCHES (OL). 3. BLOWER MOTOR SPEED SELECTIONS ARE FOR AVERAGE CONDITIONS, SEE INSTALLATION INSTRUCTIONS FOR DETAILS ON OPTIMUM SPEED SELECTION. 4. USE ONLY COPPER WIRE BETWEEN THE DISCONNECT SWITCH AND THE FURNACE JUNCTION BOX (JB). 5. THIS WIRE MUST BE CONNECTED TO FURNACE SHEETMETAL FOR CONTROL TO PROVE FLAME. 6. FACTORY CONNECTED WHEN LGPS NOT USED. 7. REPLACE ONLY WITH A 3 AMP FUSE. 8. YELLOW LEAD NOT ON ALL MOTORS. 9. BLOWER-ON DELAY, GAS HEATING 60 SECONDS, COOLING OR HEAT PUMP 2 SECONDS. 10. BLOWER-OFF DELAY, GAS HEATING 90, 135, 180 OR 225 SECONDS, COOLING OR HEAT PUMP 90 SECONDS. (135 SECONDS ONLY ON SOME MODELS) 11. IGNITION-LOCKOUT WILL OCCUR AFTER FOUR CONSECUTIVE UNSUCCESSFUL TRIALS-FOR-IGNITION. CONTROL WILL AUTO-RESET AFTER THREE HOURS. 12. SOME MODELS MAY HAVE SPADE QUICK CONNECT TERMINALS.

Briefly short the TEST terminal to the "Com 24V" terminal. Status LED will flash code and then turn ON the inducer motor. The inducer motor will run for the entire component test. The hot surface ignitor, blower motor-heat speed, and blower motor-cool speed will be turned ON for 10-15 seconds each. Gas Valve and Humidifier will not be turned on. GRYWCom HUMTEST STATUS320615-102 REV. J CONTINUOUS OFF -Check for 115VAC at L1 and L2, and 24VAC at SEC-1 and SEC-2. CONTINUOUS ON -Control has 24V power. RAPID FLASHING -Line voltage (115V) polarity reversed. If twinned, refer to twinning kit instructions. LED CODE EACH OF THE FOLLOWING STATUS CODES IS A TWO DIGIT NUMBER WITH THE FIRST DIGIT DETERMINED BY THE NUMBER OF SHORT FLASHES AND THE SECOND DIGIT BY THE NUMBER OF LONG FLASHES. STATUS 24V 11 NO PREVIOUS CODE - Stored status codes are erased when power (115V or 24V) to control is interrupted or 48 hours after each fault is cleared. 12 BLOWER ON AFTER POWER UP (115V or 24V) -Blower runs for 90 seconds, if unit is powered up during a call for heat (R-W closed). 13 LIMIT OR FLAME ROLL-OUT SWITCH LOCKOUT - Control will auto reset after three hours unless flame roll-out switch or fuse link is opened, refer to #33. 14 IGNITION LOCKOUT -Control will auto-reset after three hours. Refer to #34. 21 GAS HEATING LOCKOUT - Control will NOT auto reset. Check for: - Mis-wired gas valve -Defective control (valve relay) 22 ABNORMAL FLAME-PROVING SIGNAL - Flame is proved while gas valve is de-energized. Inducer will run until fault is cleared. Check for: - Leaky gas valve -Stuck-open gas valve 23 PRESSURE SWITCH (ES) DID NOT OPEN Check for: -Obstructed pressure tubing. - Defective pressure switch (stuck closed). 24 SECONDARY VOLTAGE FUSE IS OPEN Check for: - Short circuit in secondary voltage (24V) wiring. 31 PRESSURE, DRAFT SAFEGUARD, AUXILIARY-LIMIT (when used) , OR BLOCKED VENT SHUTOFF (when used) SW...
