The year of the first start-up must be permanentely marked on the identification plate. Make sure all existing shut-off valves of the fuel return line are open before using the system. Check the openings of the combustion air supply and exhaust pipe for dirt and clean if nessesary. After replacing the vehicles cooling fluid make sure to bleed the system of air thoroughly. Add cooling fluid when needed. After replacing the heating circuit water (solution) make sure to bleed the system of air thoroughly. Add solution when needed. (at least 20% antifreez) Make sure to use the fuel and operation power indicated on the identification plate. In case of heavy smoke development, unusual burner noise, or smell of fuel, disable the heating system by removing its fuse. Operate the system only, after a technical inspection by a SHEER trained person. Turn on the heating system at least once a month for 10 min.. The heating system must be checked by a SHEER trained person, before each heating saison. Liability claims can only be asserted, if the claimant can prove adherence to the the installation, maintenance, and safety instructions. 5

settings boiler controller Selection of space heating mode This setting is used to switch between the different operating modes. The selection made is indicated by a bar which appears below the respective symbol. Automatic mode Automatic mode controls the room temperature according to the time program. Characteristics of automatic mode: - Heating mode according to the time program - Temperature setpoints according to the heating program Comfort setpoint or Reduced setpoint - Protective functions active - Automatic summer / winter changeover (ECO functions) Continuous operation or Continuous operation maintains the room temperature at the selected operating level. Heating to Comfort setpoint Heating to Reduced setpoint Characteristics of continuous operation: - Heating mode with no time program - Protective functions active - Automatic summer / winter changeover (ECO functions) and 24-hour heating limit inactive in the case of continuous operation with Comfort setpoint Protection When using Protection mode, the heating system is off, but it remains protected against frost (frost protection temperature) provided there is no power failure. Characteristics of Protection: - Heating off - Temperature according to frost protection - Protective functions active - Automatic summer / winter changeover (ECO functions) and automatic 24-hour heating limit active Selecting the DHW heating mode The button is used to switch DHW heating mode on and off. The selection made is indicated by a bar which appears below the respective symbol. DHW heating mode - On: The DHW is heated according to the selected switching program. DHW push Triggering is effected by keeping the DHW operating mode button on the operator or room unit depressed for at least 3 seconds. It can also be started when: - The operating mode is Off - Operating mode changeover acts via H1 or centrally (LPB) - All heating circuits use the holiday function Adjusting the room temperature setpoint Turn the setting knob to increase or decrease the Comfort setpoint For the Reduced setpoint - press OK, - Select operating page Heating circuit and - adjust the Reduced setpoint After each readjustment, wait at least 2 hours, allowing the room temperature to adapt. Displaying information Various data can be displayed by pressing the info button. Error messages If this symbol appears, an error in the plant has occurred. Press the info button and read further information. Maintenance or special operation If this symbol appears, a maintenance alarm is delivered or the plant has changed to special mode. Press the info button and read further information. Manual operation When manual operation is active, the relays are no longer energized and deenergized according to the control state, but are set to a predefined manual operation state depending on their function. The burner relay energized in manual control can be deenergized by the electronic temperature controller (TR). After manual control has been activated, a change to the basic display must be made. There, the maintenance / special mode symbol appears. Press the info button to switch to info display Manual mode, where the setpoint can be adjusted. Chimney sweep function The chimney sweep function is activated by a short press (maximum 3 seconds) on the chimney sweep button. This function produces the operating state required to make emission measurements (flue gas). - Off: No DHW heating, but the protective function is active. 9
programming boiler controller Programming Settings that cannot be made directly with the operating elements require programming. For this purpose, the individual settings are structured in the form of operating pages and operating lines, thus forming functional groups of settings. The following example shows how to set the time of day and the date. Example: Setting the time of day - Press ESC to go one step back at a time, adjusted values on the previous page are not memorized. - If no setting is made for 8 minutes, the display returns to the default display. - Depending on the type of controller, some operating lines may be hidden. display pages instructions This is the default display. (If the default display does not show, press the ESC button until it shows.) Press the OK button to select the next operating page. At the bottom of this operating page are two operating lines. One of it is highlighted. Turn the setting knob until the operating line Time of day and date is highlighted. Press OK. At the bottom of this page, the last operating line shows Hours / Minutes. Press OK. Heating curve slope As the heating curve slope is raised, the flow temperature increases the quicker the lower the outside temperature or, in other words, if the room temperature is not correct at low outside temperatures but correct at higher outside temperatures, the heating curve slope requires readjustment. Increase adjustment: Decrease adjustment: Raises the flow temperature, especially when outside temperatures are low. Lowers the flow temperature, especially when outside temperatures are low. The programmed heating curve is based on a room setpoint of 20 C. If the room setpoint is adjusted, the heating curve automatically adapts to the new value. The display shows the hours flashing. Turn the setting knob to the current hours. Press OK. The display shows the minutes flashing. Turn the setting knob to the current minutes. Press OK. The settings are saved when the display stops flashing. To return to the default display press the ESC button until it shows. 10
