Logicpress: This is the same product as the Presscontrol, but with the extra features. The column of water between the switch and the highest outlet must not exceed 15 metres (1.5bar) – the “restart pressure value setting” - otherwise the system pressure may not fall to the pre-set “cut in” pressure and the system will not restart. This value is pre-set at factory, so no additional programming is required, or possible, during installation. Minimum flow required inwards is 1 litre per minute. It must be operated vertically. Optional pressure gauge (M).
Logicpress PLUS: this has the same features as the Logicpress, but is for higher flow rates and hence has a larger inlet and outlet.
