Display Panel:
Thewood grain fireplace has 2 working modes, Standby and Poweron.
StandbyMode:
Connect the fireplace plug to power supply,fireplace powered on, the display board in standby mode, powersupply light in red, all other lights off. only ON/OFF button canwork, other buttons do not work.
If itis a new fireplace, after powered on for the first time (ON/OFF instandby mode), long press MODE button for 3 seconds, feed motorlight on, continuously feeding for 4 minutes and 50 seconds thenenter into power on mode. During the feeding period, conventionblower, exhaust fan and poker do not work. Long press MODE buttonwill work as feeding only and do not have any otherfunction.
Afterpower on the fireplace, before press ON/OFF button, if detect thetemperature control switch has been closed(for example, it is a hotfireplace when power on), exhaust fan and convention blower work on220V voltage for heat radiation, the convention blower and exhaustfan will stop working when the temperature control switch off. Ifpress ON/OFF button, fireplace enter into igniteprogram.
Power onmode: Include ignite, normal work,power off, 3 procedures.
Ignite procedure:
Whenthe control board is connected with power supply, press ON/OFFbutton to power on the fireplace, the light will change from red toyellow green. MANUAL light, feed light on, exhaust fan and feedmotor start working, exhaust fan and feed motor light on. Thescreen display room temperature. When the exhaust fan startworking, fireplace inside will become negative pressure, when testthe pressure switch is closed, the poker will be ignited, pokerlight on. It takes 4 to 10 minutes from poker ignited to fireflame. When there is fire flame, the temperature will increase, andwhen the fireplace inner temperature up to65°C, the temperature control switch close,convention icon light on, convention blower start working, blow theheat into the room. Timing from the fireplace powered on to 12minutes, if convention blower already works, it means ignitesucceed, shut off the poker, ignite light off, then enter intonormal work procedure. If 12 minutes later, temperature switch donot close, convention blower do not work, then the ignite failurealarm.
PressON/OFF, feed motor continuously feeding for 3 minutes and 30seconds, stop feeding for 1minutes, then follow FEEDING 3S/STOP 4Sto feed spasmodically until ignite procedure finish. After ignite,feed under the related rank accordingly. The display board feedinglight will uniform with feed motor, feed motor work and light on,feed motor do not work then light off.
PressON/OFF, when time up to 5 minutes 30 seconds, exhaust fan voltageis 175V, after 5 minutes 30 seconds then the voltage rise to 220Vuntil ignite procedure finish. After finish igniting, exhaust fanwill work base on the related voltageaccordingly.
Duringignite procedure, press UP/DOWN button, rank light can switchcircularly, but the light will onto the working rank only whenignite finish. During ignite procedure, press MODE will notwork.
| FeedTime(Seconds) | Exhaust,Convention Voltage | ||
| 1st Rank | Feed 2/Stop5 | 175V | |
| 2nd Rank | Feed 3/Stop4 | 175V | |
| 3rd Rank | Feed 5/Stop3 | 190V | |
| 4th Rank | Feed 7/Stop3 | 205V | |
| 5th Rank | Feed 10/Stop3 | 220V(FullVoltage) |
PressON/FF and 12 minutes later, if temperature switch close, conventionblower works (175V), this means ignite succeed, and shut off poker,ignite procedure finish, enter into normal work procedure.According to different ranks, each rank will have different feedtimes, exhaust fan and convention blower voltage. Press UP/DOWNbutton can switch the rank, rank 1 to rank 5 can switch inturns.
Auto-work mode:
Thedefault work mode is manual mode, and upper descriptions for manualwork mode, can switch to auto-work mode only when the igniteprocedure succeed.
PressMODE button can switch manual mode and auto mode in turns. TheMANUAL and T-STAT lights over MODE button will show work mode.Under auto-work mode, then can set temperature, when press UP orDOWN button, screen will show the saved value in EEROM, UP increase1, DOWN reduce 1, 4 seconds later will recover display the roomtemperature. When room temperature3°F lower than settemperature, fireplace will return to original manual set rank.When room temperature the same as set temperature, fireplace willwork under the value in rank 1. Can not manual switch the rankunder auto-work mode, if want switch the rank, then must switch tomanual mode.
Power off procedure:
PressON/OFF button enter into power off mode during the fireplaceworking procedure. During power off procedure, feed motor stopwork, exhaust fan and convention blower work under full voltage,the fire flame will burn out slowly, temperature will reduceslowly, when temperature reduce and temperature switch disconnect,exhaust fan and convention blower stop working, power off finish,fireplace turn to standby mode. Timing from power off, iftemperature switch not disconnect 30 minutes later, then shut offforcibly. During power off procedure, if press ON/OFF button, thefireplace will power on again, and enter into ignite procedure.(The ignite, feed motor, exhaust fan, convention blower icons willbe show according to its related working mode)
Fault Alarm:
Ifhave fault during ignite procedure and normal work procedure, thefireplace control board will alarm. Alarm with belowsituations.
Negative pressure alarm: DisplayE2
Duringignite procedure, if pressure switch do not close, continuouslydetected for 30S and still not close, then stop igniting work andalarm. The reason for this situation may be resulted from the dooris open.
Duringnormal work, if negative pressure disappear, when control boarddetects negative pressure switch disconnect, delay 30S, if theswitch still disconnect, then it will make negative pressure alarm.Exhaust fan and convention blower work under full voltage, feedmotor and poker stop working. Temperature display will turn to E2as indicator for negative pressure alarm. After stop feeding,temperature will reduce slowly, when temperature switch disconnect,the exhaust fan and convention blower will stop, the light stillblink to remind user it makes negative pressure alarm, until userpress ON/OFF button to reset and control board turn to standby modeagain. Press ON/OFF button can not reset before the temperaturereduce.
Reset:Plug out the power cable and plug in again, press ON/OFF button topower on again.
Over-heat alarm: DisplayE1
Thereis an over-heat switch inside the fireplace, the switch is closedif fireplace not over-heat. It will disconnect when the fireplaceover-heat.
Whenthe control board detects the over-heat switch disconnected, delay30S and detect again, if still disconnect then make over-heatalarm. Convention blower and exhaust fan work under full voltage,feed motor and poker stop. E1 blink as indicator for over-heatalarm. When temperature reduces, exhaust fan and convention blowerstop, press ON/OFF to reset. Press ON/OFF button can not resetbefore the temperature reduce.
Reset:Plug out the power cable and plug in again, press ON/OFF button topower on again.
Flameout alarm: DisplayE3
Duringnormal work procedure, if detect temperature switch is disconnect,delay 30S and detect again, if still disconnect then make flameoutalarm. Feed motor stop feeding, exhaust fan and convention blowerstop working. E3 blink as indicator for flameout alarm. PressON/OFF button to reset when it alarm.
Ignite fail alarm: DisplayE4
Iftemperature switch do not close after ignite for 12 minutes,convention blower do not work then make ignite failalarm.
Timingfrom ignite start, if 12 minutes later, temperature still notincrease to make the temperature switch close then make ignite failalarm. Exhaust fan and convention blower work under full voltage,E4 blink as indicator for ignite fail alarm.
Reset:Press ON/OFF button to reset.
Temperature sensor fault alarm: DisplayE5
Afterconnect with power supply, it will display room temperatureautomatically. Temperature sensor fault will displayE5.
Afteropen the feed door, feed light off and stop feeding. If feed doorfault (open circuit) or door not well closed, then feed light offand stop feeding.
Remotecontrol:
Thereare 4 buttons on the remote control, the function is the same asdisplay board.
°C/°F switchtemperature: Press UP and DOWN buttons for 3S at the same time,after hear “BEEP” sound, temperature display switchsucceed.
