General Functions "W" Input On (Call for Heat) Checks to see weight switch open Turns on Inducer Pressure Switch Closes; 15 Second Pre-Purge Starts Sparking & Gas Valve Turns On for 7 Seconds Flame Sensed Anytime During Spark Gas Valve Stays On Blower Comes On following 30 Second Delay "W" Input Off (Call for Heat Satisfied) Gas Valve De-Energizes Immediately Inducer Remains on for 29 Second Post Purge Indoor Blower De-Energizes after Selected Blower Off Delay

Slide 56

General Functions Continued.... Single Compressor Mode (Tab is not Broken) "Y" Input On (Call for Cooling) 3 Minute Anti-Short Cycle Timer from the time the compressor was keep going on. Cooling Speed Blower following a 7 second postponement "Y" Input Off (Call for Cool Satisfied) Cooling Speed Fan Off following 60 Second Delay Dual Compressor Mode (Tab is Broken) first Stage Compressor is Energized Externally "Y" Input On for second Stage Cooling following 7 Second Delay "Y" Input Off ; Cooling Speed Fan off following 60 Second Delay

Slide 57

General Functions Continued.... "G" Input On (Call For Fan) Fan Immediately on Heat Speed "G" Input Off Fan Immediately Shuts Off If "Y" input Occurs During "G" Blower Switches to Cooling Speed If "W" Occurs During "G" Blower off when Heat Blower On Delay Begins Continuous Fan Operates while control is in Heat Mode Lockout Test/Speed-Up Bypasses Compressor Short-Cycle Timer If Shorted for Over 4 Minutes ; Control Ignores = Operates Normal

Slide 58

Diagnostic Codes Steady On = Normal Operation in Standby 1 Flash = Lockout for Ignition Failure or Flame Dropouts 3 Trials for Ignition or 5 Flame Losses 2 Flashes = Pressure Switch Open with Inducer On 3 Flashes = Pressure Switch Stuck Closed with Inducer Off 4 Flashes = Limit Switch Open Heat Speed Blower and Inducer On Until Limit Closes Blower Runs through Off Delay; Inducer runs through 29 Second Post-Purge 5 Flashes = Flame Detected with Gas Valve Off Blower and Inducer Both On Until No Longer Sensed Control Locks out But Senses Limit and Flame Control is Reset By Removing Power or following 1 Hour Automatically 6 Flashes = Compressor Delayed for Short Cycle/Staging Timer Status Light Off = Board Hardware Fault

Slide 59

Flame Sense Checking Digital Meter set for least uA Setting Meter in arrangement with Flame Sense Rod Wire Control must read at least .5uA amid fire detecting period Average current perusing is around 3-5uA. Control continually screens Flame amid warming operation Issue: Flame Sense Rod gets eroded ; Clean w/steel fleece Issue: Flame Rod not arranged in Flame Correctly

Slide 60

Ground Check Meter set to Ohms or Resistance Setting Place Meter from P1-6 or COM fast associate with case ground Reading ought to be close to Zero ohms Issue: COM Quick Connect Loose ; causes board resetting when blower begins Issue: Flame Sensing issues if despicable establishing in framework

Slide 61

GPG TROUBLESHOOTING THEORY OF OPERATION Control of warming, cooling, and fan works because of a standard indoor regulator Direct start utilizing a chip to control timing, fire detecting, and start retries Monitoring of framework weight switch and breaking point switch Control of gas valve, indoor fan, and initiated draft engine in view of the indoor regulator request and status of security data sources Control of compressor contactor Diagnostic marker to give data on energy to the control and control status

Slide 62

GPG TROUBLESHOOTING Summary of Timing Functions (in seconds) 1. Warm speed delay on and off happen simply after fire has been detected and fundamental valve (MV) is invigorated Selectable with jumpers 3. Demonstrates timing when "Two Stage Comp" tab is severed, clock gets to be postponement on make 4. Shows timing when "Two Stage comp"tab is not severed, clock gets to be compressor bolt out between cycles(I.e. Least planning between compressor cycles) 5. Prepurge timing (not postpone on )
