RECEIPT & INSPECTION
After receiving, inspect the unit for any possible physical damage that may have
occurred during transportation. After unpacking the unit make sure the box contains:
• 1 x WPS-0100 (Temperature & Pressure Sensor)
• 2 x EPDM Flat Washers
• 1 x Dual unions, tailpieces - NPT, sweat, press
• 1 x Flow pipe and tube with connection ttings
• Instruction Manual
Make sure the part number on the unit corresponds to the part number on

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. WFS 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

dEscriPtion
Install the temperature and pressure sensor in a location that will be easy to perform
periodic maintenance. Install shut-off valves upstream and downstream of the
sensors to aid installation and maintenance. Install a strainer or other ltering device
upstream of the ow and pressure sensors.
The rst length of straight of pipe connected to the ow sensor must be a
minimum of 3” long prior to a bend for the sensor to register a proper reading.

Recommended Fluid Concentration
Heating: 0-50%
Cooling: 0-30%
While initially lling the system take care to not produce any water hammer
at the sensor. Slowly increase initial ow and pressure to the sensor. Failure to
do so can cause the sensor to fail.
INSTALLATION
No pipe tape/dope
should be used on
threads.
Sensor can be mounted
Vetically or horizontally
within a 180 arc.
Sensor CANNOT be
mounted pointing below
