2 2 Lago Edition Boiler controller with direct heating circuit and hot-water function Lago Basic 0101/1001 Boiler module / Mixer module Basic function Control of a fixed flow temperature or a fixed return temperature by controlling a heat generator or mixer. A room thermostat or timer (24 V) can be connected. Hot-water function via sensor or thermostat. Weather- and room temperature-dependent flow temperature control by controlling a heat generator or mixer (time-dependent control available with add-on module). Heating module in a cascade. Performance features Safety temperature limiter test Cooling operating mode (1001 in conjunction with mixer operation) Start-up relief Frost protection function Charging pump relief Circulation pump control (not with fixed value control) Pump blocking protection Mixer blocking protection Delayed pump switch-off Choice of sensor (5 kω NTC <-> 1 kω PTC) The Lago Basic is a basic module, which is suitable for the most diverse applications and is expansible for a more specific application. This controller is suitable for wall mounting. The electrical connection of the controller and the control components is possible via screw terminal blocks in the base. The controller features a demand-related pump circuit for every heating circuit. When connected to an outdoor sensor, the controller calculates a boiler or flow temperature based on the outside temperature, which can then be supplemented by a room control module with time control (see accessories). Control of a fixed flow temperature or a fixed return temperature by controlling a heat generator or mixer is achievable with the Lago Basic. The Lago Basic can also act as part of a cascade control. Here it is feasible to use it as a boiler or heating circuit controller. Display mode In the normal mode Run, the flow temperature of the heat generator or heating circuit is displayed. The following temperatures are given: 1. Outside temperature 2. Hot-water temperature 3. Room temperature Information about outputs Burner ON / Mixer OPENS Feed pump ON / Mixer CLOSES Heat generator pump ON / Heating circuit pump ON Bus communication OK

3 Lago Edition Boiler controller in cascade mode Boiler controller with header pump / mixer extension

4 4 Lago Edition Lago 0321 Basic function The unit includes the control for a one-stage heat generator, a process water generator and for a maximum of two heating circuits (one with mixer). Saving functions (demand-related circulation pump control) are also integrated. Alternatively, the pump relay of the direct heating circuit can also be used for the following functions: Circulation pump Return temperature increase Header pump If no heat generator sensor is connected, the unit can be used as a mixer extension. When a heat generator sensor is connected and an address is set (bus ID), the heat generator can be used in a cascade. It is then activated by a system controller.
