Trane CNT05639 Electronic Flow Switch Control Monitor 90-240VAC For SEN01674 Flow Sensor CH530 UC800

CNT05639 is the monitoring unit of Trane's original factory electronic water flow switch (model: CONTROL; MONITOR FOR FLOW SENSOR, AC90~240). CNT stands for Control, not the probe or the entire switch. It is combined with SEN01674 calorimetric probe, FTG01145 clamp adapter, and CON01379 three-meter connector cable to form a four-piece set. The probe determines the flow rate by two PTC sensors, without blades or moving parts, resistant to dirt and water scale, and replaces mechanical flow switches and differential pressure switches with solid state. It operates within a 90–240 VAC wide voltage range, with a -25~80℃ temperature range, adjustable insertion depth, and LED light column indicating low/high flow. It can be adjusted for set points and Hold for 6 seconds for calibration; a loss of flow indicates a water flow fault and triggers a shutdown. It is compatible with CH530, UC400, and UC800 platform units. When placing an order, it is necessary to check if the four-piece set is complete. Do not mix it with 24V's SC0522/0523/0525, SWT03335, or use it on the IPC/LLID bus.
