Pentair Ichlor Flow Switch – Temperature Sensor 1/2″ Mpt – 3 Wire Leads – 523100

Description

Pentair Flow Switch 1/2″ mpt with integrated Temperature Sensor 3 Wire Leads for Flow and Temperature (replaces older 4 wire Switches) For Ichlor 15 and Ichlor 30 Salt Generator Cells 1.0 amp Model #: Q-12DST-C2 Harwil Flow/ Temp Switch MPN: 523100 UPC: 788379878788 The flow switch also contains a thermistor that senses water temperature. The water temperature is used for the salinity calculation. If the thermistor is failing the salinity will be incorrect. Flow switch has 3 wires on cells manufactured after September 2018, green wire not used on cells made after 2018 Red – flow switch White – temperature sensor Black – common Green wire no longer used on Intellichlor cells after 2018 The IntelliChlor uses the Harwil Q-12DST-C2 flow switch. It has an integrated 10k thermistor for temperature sensing When the sensor fails and the software detects failure, it defaults to a standard temperature of 77 F Pentair part number 520736 need to reference the manual included with the part. Per the manual included in the box for the 520736 switch; switches manufactured before September 2018 are four wires, switches manufactured after September 18th are three wires. Three wire switches will work with four wire cells but four wire switches will not work with three wire cells. Three wire cells were manufactured after September 2018.
