See assembly instructions/functional description for room temperature sensor FRA 2.1.6 Boiler enable input When setting the system type, the parameter "Boiler enable input available" is preset to enable potential analysis of an external floating release or start contact. Boiler enable input available YES This is set if the boiler enable input is available. As long as the contact is closed, the controls operate according to the specified operating mode. If the external contact is opened, the boiler loses the enable and follows the shutdown procedure. As soon as the handle is opened, the controls cease to accept any heat requirement (e.g. flue gas thermostat of a supply boiler). Boiler enable input available NO This is set if there is a boiler start input or no allocation. As long as the contact is open, the controls operate according to the specified parameters. If the external contact is closed, the boiler starts and works in continuous operation. (e.g. heat requirements of a heating fan) Note: No handle required for operation. If the boiler is enabled or started by the parameter, it goes at least to "Heating" status, even if the signal has stopped in the meantime. Only then does the boiler follow the shutdown procedure. 10 Froling GesmbH A-4710 Grieskirchen, Industriestraße 12 www.froeling.com

The screen is disabled for 10 seconds to allow you to clean it without opening a menu or inadvertently adjusting a parameter. 4.9 Boiler modes 4.9.1 Explanation of terms Boiler time The time in which the boiler is producing heat, i.e. during this time the boiler is adjusted to its boiler temperature setpoint. Outside this time there is no heat available for the heating system. If there is a storage tank, the boiler time is replaced by the storage time Heating times of the boiler Storage tank loading time The time in which the storage tank can be loaded by the boiler, provided that the criterion for starting the boiler is met ("Boiler start if difference between boiler setpoint and top store is larger parameter). Storage tank loading only takes place within the defined time window. Heating times of the storage tank Heating time The time in which the heating circuit is supplied at the desired temperature. Outside this time (setback mode) the heating circuit is supplied at reduced temperature. Requirement: a sufficiently high temperature in the boiler or top storage tank. See "Heating times of the heating circuits" [page 60] DHW tank loading time The time in which DHW tank loading is released. Requirement: The DHW tank temperature is below the minimum value and the boiler or storage tank temperature is sufficiently high. See "Heating times of the DHW tank" [page 66] Filling time This is the time at which the filling process of the day store is started. In this way you can prevent the filling process starting automatically at inappropriate times (e.g. when people are asleep). Note: The boiler is turned off for filling. For this reason we recommend that the filling times be set before or after the storage tank loading times to ensure that energy is provided at these times. 42 Froling GesmbH A-4710 Grieskirchen, Industriestraße 12 www.froeling.com

Operation Boiler modes 4 4.9.2 Transition op. without storage tank In transition operation without a storage tank the boiler only produces heat during the specified boiler times. Outside these times the boiler follows the shutdown procedure and switches to "Standby" status. It is, therefore, important to note that in this mode the heating circuits and DHW tank are only supplied with heat during the boiler times. In example 1 the boiler times have been set to cover the necessary heat requirement. The heating times and DHW tank loading times have been set within the boiler time range, with the heating time being extended approximately one hour beyond the boiler time. This allows the residual energy in the boiler to be used by the heating circuits after the end of the boiler time. Note that outside the boiler times for setback mode, heat is only available until the boiler temperature falls below the setting value (parameter "Pumps start at"). Example 1: Transition operation without storage tank Boiler heating time 1 Boiler heating time 2 Heating time 1 Heating time 2 Setback mode DHW tank loading time 1 DHW tank loading time 2 Tip: In systems with solar panels, choose the DHW tank loading time so that solar energy can be used. Example 2: Transition operation without storage tank with solar panel system Time Boiler heating time 1 Boiler heating time 2 Heating time 1 Heating time 2 Setback mode DHW tank loading time 1 Time Operating Instructions Lambdatronic P 3200 P1 - Touch B1030114_en 43

4 Operation Boiler modes 4.9.3 Transition op. with storage tank In transition operation with storage tank the boiler only produces heat if the storage tank actually requests heat within the specified storage tank loading time. Outside these times the boiler is in Standby" status. The heating times should be set within the storage tank loading times so that the provision of heat is guaranteed over the entire heating time. Note that the heating circuit and DHW tank are only supplied with heat if the storage tank temperature is sufficient for the requirement. Example 1: Transition operation with storage tank Storage tank loading time 1 Heating time 1 Heating time 2 Setback mode DHW tank loading time 1 DHW tank loading time 2 Tip. In systems with a storage tank and solar panels, choose the storage tank loading time so that solar energy can be used. Time In order to ensure that there is sufficient heat at the start of the DHW tank loading time and heating time, we recommend setting the storage tank charging time to begin before the start of the DHW tank time or heating time. Example 2: Transition operation with storage tank and solar panel system Storage tank loading time 1 Heating time 1 Heating time 2 Setback mode DHW tank loading time 1 DHW tank loading time 2 Time 44 Froling GesmbH A-4710 Grieskirchen, Industriestraße 12 www.froeling.com

Operation Boiler modes 4 4.9.4 Winter op. without storage tank In winter operation the boiler produces heat around the clock, in other words it tries to maintain its boiler temperature setpoint 24 hours a day. The boiler time settings are ignored in this mode. The heating times and DHW tank loading times can be distributed throughout the day as required. Example 1: Winter operation Heating time 1 Heating time 2 Setback mode DHW tank loading time 1 DHW tank loading time 2 Tip: In systems with solar panels, choose the DHW tank loading time so that solar energy can be used. Example 2: Winter operation with solar panel system Heating time 1 Heating time 2 Setback mode Time DHW tank loading time 1 Time 4.9. Winter op. with storage tank To ensure efficient operation, set systems with a storage tank to transition op. rather than winter op. Set systems with a storage tank to transition op.

Operation Boiler modes 4 4.9.7 Summer op. with storage tank In systems with a storage tank, note that in summer operation the storage tank loading times remain active as the DHW tank is supplied with heat from the storage tank. Within the storage tank loading time the boiler only produces heat if the storage tank temperature is below the minimum value and the DHW tank is requesting heat. Example 1: Summer operation with storage tank Storage tank loading time 1 DHW tank laoding time 1 DHW tank loading time 2 Tip: In systems with a storage tank and solar panels, choose the storage tank loading time so that solar energy can be used.

High temperature requirement because of DHW tank 1 loading High temperature requirement because of DHW tank loading For high temperature requirement don't look at DHW tank 01 NO NO NO If DHW tank 1 is supplied directly from the heating circuit as well as the isolating valve, this parameter must be set to YES. If there is a requirement from the DHW tank and the criteria for DHW tank loading have been met, the isolating valve immediately clears the way for boiler loading. The heating circuit pump starts running as soon as the Load if temperature difference between boiler and DHW tank is criterion is reached. Once DHW tank loading is complete, the heating circuit pump will stop, the isolating valve will remain active for a specified period of time and the heating circuit mixer will close. If time has run out, the heating circuit will go back to being supplied on a weather-compensated basis. NOTE: only available with heating circuit 1 and generally only used in conjunction with the unit model of the P1 Pellet pellet boiler! If this parameter is set to YES, the remote line is operated according to the set heating curve + overcharge. Whilst the DHW tank is loading, the remote line is supplied for a short time at a higher temperature, but once the DHW tank is loaded, it is supplied again according to the heating curve. NOTE: s for heating circuit 2 only! If DHW tank 1 is positioned in front of the network mixer, it should not affect the temperature control of the remote line, therefore this parameter should be set to YES.

PWM / 0-10V settings.17 PWM / 0-10V settings Normal pump (pump with load-tap changer) Set when a standard pump a switching valve with RC element is run at the respective output. When using a switching valve, set the minimum speed of the output to 100%. When a pump is used, it is controlled at the 230V output using pulse packets. PDM / field pump There is a permanent power supply of 230V at the output for the high efficiency pump. The pump is controlled using pulse duration modulation at the respective PDM output. PDM / Solar pump Here again, the pump is controlled by means of pulse duration modulation at the respective PDM output. In this case, however, the characteristic line is inverted and can only be used for specially marked high efficiency solar pumps. PDM field Pump+valve The signal for the field pump is emitted at the PDM output. If the signal exceeds 2%, the 230V output is switched on. If the signal is below 2% for more than 4 minutes, the output is switched off again. 0 10V / field pump 0 10V / solar pump 0 10V field Pump+valve The same functions that apply with PDM apply to the parameter values with 0-10V. The only difference is that instead of pulse duration modulation, a 0-10V signal is used to control the pump. Operating Instructions Lambdatronic P 3200 P1 - Touch B1030114_en 123

6 Troubleshooting Procedure for fault messages 6 Troubleshooting The term "fault" is a collective term for warnings, errors and alarms. The boiler reacts differently to the three types of message: WARNING ERROR ALARM In case of warnings the status LED flashes orange and the boiler initially continues controlled operation. When there is an error, the status LED flashes red, the boiler follows the shutdown procedure and remains in Fault status until the problem is resolved. An alarm triggers a system emergency stop. The status LED flashes red, the boiler switches off immediately and the heating circuit controller and pumps remain active. A window with the corresponding fault text will also appear. Pressing the Cancel icon takes you back to the basic display. If the quick select icon and the warning triangle flash alternately, there is still a fault. The Error display button will now appear in the quick menu. 6.1 Procedure for fault messages If you open the window with the respective fault text, the right arrow will take you to possible causes of the fault. 124 Froling GesmbH A-4710 Grieskirchen, Industriestraße 12 www.froeling.com

Troubleshooting Procedure for fault messages 6 Tapping Solution will also display action to be taken to resolve the problem. If there are several options available, these will be listed one below the other. Once the fault has been resolved, tap the Cancel icon to return to the basic display.
