Cleaning programme R + number of seconds it has yet to run After 1 hour continuous operation in heating mode the stove starts an automatic cleaning cycle of 120 seconds duration. Specifically, pellet feed rate is reduced and fan speed is increased to reduce the amount of pellets in the burner pot and remove the flue ash from it. Fan after-run (=stove switches off; 15 minutes duration) The stove switches off. The fan runs for another 15 minutes to completely burn down the remaining pellets and carry off the flue gas. Note: Only when G OFF does not flash alternately with HE OFF or TW OFF does the stove go into standby after fan afterrun is over. In all other cases the stove restarts automatically after fan after-run is over. Heat exchanger is cut off by a thermal switch ( Service prompt (appears briefly) heat is not fed into the heating system) The stove switches off via an internal control mechanism because boiler water temperature TW > 80 °C. The stove restarts automatically after the temperature has dropped sufficiently. Message only valid for Waterplus appliances. example: RA 0. 1 = servicing overdue since 0. 1 t pellets. "Function currently not available" This display message appears when the function you have called up is currently not available or if there is no function assigned to the key you have pressed. HE . . . HM 2. 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 (2 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). © Wodtke GmbH Tübingen.
