[. . . ] 950 325 Page 2 / 4 Display Messages Display message Explanation "Standby dot"; appliance has been switched off manually via I/O key. The stove does not respond to external controllers when in standby mode. PL AUF AL AUF FT AUF PE res ON start signal (appears briefly when you switch on the stove) The stove has been started. After briefly showing the programme being used it enters the TEST phase. OFF stop signal (appears briefly or alternates with "A" for 4 minutes when you switch off the stove) The stove has been switched off and after going through phases A1 ­ A4 enters fan after-run phase G OFF. This is the programme and programme version (appears for some seconds during start-up). B1 = programme for 3 ­ 9 kW stove; B2 = 3 ­ 11 kW; B3 = 3 ­ 13 kW; B4 = 3 ­ 13 kW 001 = programme version 1; 002 = programme version 2; flashes alternately with TEst (see below). TEST phase (appears after starting the stove) Checks all stove functions; flue gas exhaust flap cycle starts. [. . . ] The stove restarts automatically after the temperature has dropped sufficiently. The stove needs cleaning; example: RA 0. 1 = cleaning overdue since 0. 1 t pellets. Service prompt (appears briefly) The stove needs servicing. example: RA 0. 1 = servicing overdue since 0. 1 t pellets. Fuel hopper open The hinged cover of the fuel hopper is open. If it is open for longer than 3 minutes without interruption while the stove is in operation (display shows Test, A, H, HM, H. M, HE, HE OFF, TW OFF, G OFF), this will produce an error shutdown (PL Err). Ashpit door open The ashpit door is open in standby mode. If it is open for longer than 3 minutes without interruption while the stove is running (display shows Test, A, H, HM, H. M, HE, HE OFF, TW OFF, G OFF), this will immediately cause an error shutdown (AL Err). Only open the ashpit door when the stove is not running! Firedoor open The firedoor is open in standby mode. If the firedoor is opened while the stove is in operation (display shows Test, A, H, HM, H. M, HE, G OFF), the stove will immediately produce an error shutdown (FT Err). Only open the firedoor when the stove is not running! Fuel level below reserve line The fuel hopper is almost empty and should be refilled immediately. If the display message PE res appears for longer than 5 minutes the stove will produce an error shutdown (PE Err). "Function currently not available" This display message appears when the function you have called up is currently not available (e. g. switching off the appliance while an automatic routine such as grate cycle/ash removal is still running. HE . . . HM 3. 0 HE OFF Externally controlled heating programme (only possible with external modulating controller) The stove is being operated at the indicated output level via an external controller; example: HE 7. 2 = heating programme running at 7. 2 kW via an external controller Heating programme running at minimum level (only possible with external controller) The stove has been set to its minimum output level (3 kW) via an external controller (MIN/MAX input). Note: Don't confuse H. M (dot between H and M ­ internal) with HM (no dot ­ external). Heating programme switched off via external controller (only possible with external controller) The stove has been switched off via an external controller (via input ON/OFF or BUS). Subject to change without notice. Page 3 / 4 Error Codes In the event of errors of error class 1 (F1) use the error code to find the cause of the error, rectify the error and then do a reset by pressing the I/O key. In the event of class 2 errors (F2) the stove automatically carries out a reset as soon as the cause has been eliminated. Display Error class (F1) or (F2) / Cause of error message RE (F1) ­ Bridge wire at "auxiliary input" (RE) open or error in external component/device connected to it. Er1 PE (F1) - Fuel level (error message "PE Res") permanently below reserve line / minimum filling level for Err longer than 5 minutes replenish pellets!RO (F1) ­ Grate hasn't reached "open" position (RO) ashpit full ( clear ashpit). Swivelling grate Err possibly soiled / jammed or grate motor / limit switch / grate axis driver / cabling defective. [. . . ] Shows the combustion temperature currently measured by the TR sensor in the firebox. Shows the water temperature currently measured by the internal boiler sensor in the heat exchanger Shows whether the "Pumpe" (pump) output is live (ON) or not (OFF) Functional message ON = stove is running (though error may be present) OFF = stove not in operation Collective error message = no error OFF = has produced an error shutdown / has been switched off manually Error message from temperature sensor at pellet chute (TP) ON = temperature at pellet chute (TP) too high OFF = temperature at pellet chute (TP) ok Functional message (via monitored potential-free safety relay) ON = stove is running (though error may be present) OFF = stove not in operation Example: BW 56 = 560 hours since last servicing Example: BG 56 = 5, 600 total operating hours. Examples: PR ­0. 9 = another 0. 9 t of pellets can be burnt before the next cleaning becomes due. PR 0. 2 = cleaning overdue since 0. 2 t Examples: PW -2. 9 = another 2. 9 t of pellets can be burnt before the next servicing becomes due. [. . . ]
