When a sensor is incorporated the maximum working pressure is as follows: 25.0 bar with either the IPS44 or VTU sensor, (unless they are used on a pump with a maximum working pressure of 16.0 bar, in this instance the lesser pressure applies). The MBS3000 sensor can be used on all models, the pump maximum working pressure applies. Cold water use only.
