Anleitung Zusammenfassung


The HSI, blower motor FAN speed (AMBER LED boards only) HEAT speed, and COOL speed will run for 10 – 15seconds each. Gas valve and humidifier will not be turned on. Was there a previous status codeother than #11? Is door switch closed?Is there 115V going to switch? Replace door switch. Replace transformer. Does the control respond to W, Y1 (if present), Y/Y2, and G (24V) thermostat signals? Run system through a heating or cooling cycle to check operation. Status codes are erased after 72 hours. On RED LED boards storedstatus codes can also be erased whenever (115V or 24V) is interrupted. Replace furnace control. Close door switch and go back to START. Is circuit breaker closed? Check for continuity in wire from circuit breaker to furnace.Close circuit breaker and go back to START. Check room thermostat orinterconnecting cable. Is 24V present at W, Y1 (if present), Y/Y2 or G thermostat terminals on the furnace control? Disconnect all the thermostat wires from thefurnace control.Does the problem repeat when usinga jumper wire?The thermostat is not compatible with the furnace control. Either install a ballast resistor, connect the Com24V thermostat terminal tothe thermostat, or replace the thermostat. NO YES YES NO NO YES YES YESYES NO YESYES NO YES NO YES NO NONOYES NOYESNO START TROUBLESHOOTING GUIDE NO Is LED status light on?Is LED status light blinking rapidly without apause?Is LED status light blinking ON/OFF slowly with a combination of short and long flashes? Determine status code. The status code is a2 digit number with the first digit determined by the number of short flashes and the seconddigit by the number of long flashes?Go to section below for the status code thatwas flashed. Is there 115V at L1 and L2?Is there 24V at SEC-1 and SEC-2? Replace furnace control. Check for correct line voltage polarity and ground- ing. If units are twinned, check for proper low-voltage (24V) transformer phasing.To recall status code briefly remove and reconnect one RED wire from the Limit Switch or Flame Rollout switch to display stored status code. On RED LEDcontrol do not remove power or blower access panel before initiating statuscode recall. You can also recall the previous status code by momentarily shorting the TEST/TWIN terminal to Com24V terminal until the LED goes out. LED will flash the previous status code or status code #11 (1 short and 1 long flash) ifthere was no previous code. After the control repeats the code 4 times, the control will go through a brief component test sequence. The inducer will start and run for the entire component test.

On RED LEDboards stored status codes can also be erased whenever power (115V or 24V) is interrupted. Run system through a heating or cooling cycle to check system. 12 BLOWER ON AFTER POWER UP – (115V OR 24V) – Normal operation. Blower runs for 90 seconds, if unit ispowered up during a call for heat (R-Wclosed) or when (R-W opens) during theblower on-delay period. 13 LIMIT CIRCUIT LOCKOUT – Lockoutoccurs if the limit or flame rollout switch is open longer than 3 minutes. Control will auto-reset after 3 hours. See code 33. 14 IGNITION LOCKOUT – System failed toignite gas and prove flame in 4 attempts. Control will auto-reset after 3 hours. See status code 34. 21 GAS HEATING LOCKOUT – Turn offpower and wait 5 minutes to retry. Check for: - Stuck closed gas valve relay on control. - Miswire or short to gas valve wire. 22 ABNORMAL FLAME-PROVING SIGNALFlame is proved while gas valve is de- energized. Inducer will run until fault iscleared. Check for: - Stuck open or leaky gas valve. 23 PRE...
