| When switched off manually or after a maximum operating time of 60 minutes or the coolant reaches a temperature of 84° C, combustion is ended and the run-on mode begins. The circulation pump -V55- and the combustion air blower -V6-, however, continue to run to cool down the auxiliary heater (run-on mode) and are switched off automatically. |
Note | The post-operation period of the recirculating pump -V55- and the combustion air blower -V6- depend on the operating mode in which the auxiliary heater was switched off. |
| The post-operation period is 175 seconds when heater is switched off during full-load and 110 seconds for part-load. |
| Depending on the control unit software version, slight deviations in the specified run-on values are possible. |
