Information about the handbook 1.1 Symbols Important information Important information/instructions are highlighted in this way (with lines above and below the text). 1.2 Concept explanation Heat distribution Indicates all components of the heating system used to store heat (buffer / hot water tank) or distribute it (the hot water circuit itself), as well as connections to alternative energy sources (solar system, external boiler).

• Your pellet heating system has a thermal capacity that varies from 30% to 100% of nominal power, and is automati- cally self-regulating in relation to demand. The equipment should be run as far as possible at moderate to high power (depending on heating demand), in order to avoid unnecessary emissions in low power mode.
Operating limits: Max. ambient temperature 0-45° C; max. humidity 0-95 % Only use original Biotech Energietechnik GmbH spare parts! Biotech Energietechnik GmbH guarantees repairs and supply of spare parts for at least 10 years after the date of purchase! Safety information and instructions...

Status display The following symbols apply to multiple component types. Component-specific symbols are detailed below for each component separately. The entire system/boiler/power distribution or component is switched off. None Ready The component is in standby. When all start conditions are satisfied, it goes into active Symbol mode.

5.3.1.5 Hot water Charging starts when the time is within an active time window and the hot water tank temperature is below the "Switch on temperature" setting. If the temperature rises to above the "Switch off temperature" setting, charging stops. If the time window expires during a charge cycle, the cycle is continued until the deactivation temperature is reached.
5.3.1.6 Heating circuit The heating circuit is controlled by the ambient temperature, i.e. the flow temperature is determined in relation to the outdoor temperature. Up to three time phases can be set per day, in which the target temperature is given by the "Day temperature"...

5.3.2.5 Boiler log The controller saves the most important heating system operating values every day. In order to analyse this data / optimise operation of the system, these records can be displayed on the controller. ...
5.3.2.6 Energy log See Boiler log, page 22 Shows the heat distribution records. 5.3.2.7 Components When the boiler is running, you can select components (boiler, buffer, heating circuit, etc.) to display the status of their units and the values of the corresponding sensors. If the boiler is off and in standby (heating operation must have shut down in an orderly manner), all outputs can be turned on/off If a unit is to be automatically turned on/off while its page is open, its status does not change.

B. Frost protection Each component has its own frost protection process. Buffer If the buffer is off (power manager Off or mode Off), charging is started when indicated by the activation/deactivation temperature, regardless of the time settings. Hot water If the hot water tank is off (power manager Off or mode Off), charging is started when indicated by the activation/deactivation temperature, regardless of the time settings.
