DEVICE WIRING
1/2: Input Power: This input is to power the sensor. 1 Amps at 24VAC is required to
power this device.
3. Ground Power: This input is for the ground wire. WPS Sensor must be grounded to
the pipe. Refer to Device Wiring (Page 7-8).
4. Thermistor Input: Pins 4, 3 Optional temperature sensor. (Ex. Tank temp)
Under no circumstance should power be applied to these terminals!
Permanent damage to the controller’s circuitry may result.
5. Triac Output: Pins 5, 2 This input is to send a triac output to energize a relay. 24VAC
is required to power the triac. Optional
6: Modulating Output: This output carries the modulating signal (0.5 – 3.5 VDC) to
modulate the device. Optional
