DHW flow switch ProKondens ET pos. 26 Intercal 88.20270-0230

Flow switch for the domestic hot water circuit of ProKondens ET boilers. This sensor detects the start of water draw-off and sends a signal to activate DHW mode. If the switch malfunctions, the boiler may not respond to opening the tap or may operate intermittently. Replacing the part restores correct hot water operation. The switch is sensitive to minimal water flow, ensuring quick switching. Installation is simple but requires care when connecting the wiring.
