Buderus outdoor sensor

I have a buderus logomax 142-30 and the boiler temp will not rise above 130 degrees, is there anyway to by pass the outdoor sensor to help this boiler get to 180 degrees. The sensor was damaged during construction and a new one won’t be here for a few days. I would appreciate any advice. Thanks

    Try disconnecting the sensor wires. This will fake the control out and it will think it's cold out and should send you to full heat. Worth a try

    How cold is it out side ? This may be the correct temperature with the outdoor reset control . Turn the large knob to look up outdoor temperature . If it looks correct, the sensor is ok .

    For safety concerns why do you want 180* ?

    The sensor was damaged want it to operate at normal boiler temp for now till the new sensor comes in. I am familiar with larrs and navien products.

    You can switch it to manual and set the boiler temperature with the knob . Just beware if you using a indirect for hot water and the Logamatic controls the temperature . You need to set the temperature below 150* , The hot water relief blow off at 150* ...
