Hello,
we have a new heating system installed. Model Buderus Logamax. Due to various circumstances (illness, the COVID-19 pandemic, etc.), I unfortunately did not receive an introduction or instructions. Maybe someone here can help?
In the menu under "Heating," there are options for "Heating" and "Lowering" with a temperature set behind them (currently set to 22°C (72°F) for heating and 15°C (59°F) for lowering).
There seems to be an outdoor temperature sensor installed, as this value is shown in the info menu—for example, today it shows 15.5°C (60°F). There does apparently not appear to be a room temperature sensor, since this value is not displayed.
Now I am wondering: how does the heating system detect the room temperature? Because if I understood correctly, with "Heating" and "Lowering" I set the desired room temperature for day (heating from 6 a.m.) and night (lowering from 11 p.m.), right? But how does the system know when this temperature is reached?
The radiators don’t get properly warm, only lukewarm at most. All radiators have been bled. With the old oil heating system, they became very hot.
Best regards

Hello,
Please check the settings in the submenu. Press and hold the menu button for 3 seconds to access the deeper menu levels, then post the settings here. After that, look under "Commissioning" and "Heating Circuit 1." Which heating system is listed there?
Which controller is installed?

we have the same heating system as you. At an outside temperature of 15.5°C (60°F), you will have a low supply temperature (the system adjusts this automatically). During transitional seasons, this can result in a supply temperature that is too low for the house. In that case, you can simply raise your desired room temperature, which will increase the supply temperature at higher outside temperatures. Otherwise, as mentioned above, you will need to manually adjust the heating curve in the menu.
If you have any trouble with this, feel free to contact me again.

T_im_Norden5 May 2020 21:24In simple terms, the heating system works like this:
The heating system does not know the actual temperature inside the rooms.
The outdoor sensor measures the temperature, and based on a curve stored in the device, the system produces hot water accordingly.
The 22 degrees Celsius (72°F) is a calculated temperature and does not have to match the room temperature.
To optimize the heating system, you should perform a hydraulic balancing.
It is very important to know that the thermostatic valves in the rooms are only there to reduce heating when there is external heat.
The room temperature is controlled solely by the heating system.
The heating curve adjusts the ratio: for example, at 7 degrees Celsius (45°F) outside temperature, the system produces 45 degrees Celsius (113°F) hot water to reach a room temperature of 22 degrees Celsius (72°F).
The lower this temperature (flow temperature) is, the more efficient your condensing boiler or heat pump operates.
