INTRODUCTION
This manual will help with the installation, parameter setting, trouble shooting and general
maintenance requirements for the Controller. To guarantee the safe and reliable operation
of this Control, you must rst read this manual in detail and take particular note to any and all
warnings or caution directives prior to connecting to AC power.
Only suitably qualied individuals with formal training in electrical and HVAC controls should
attempt the installation of this equipment. Incorrect wiring and installation will affect the
warranty provided with this unit. Wiring must be completed in accordance with the codes and
practices applicable to the jurisdiction for the actual installation.
The HBX Sensorlinx™ Metering System is a microprocessor based controller and as such is not
to be regarded as a safety (limit) control. Please consult and install the heating or cooling
appliance in accordance with the manufacturer’s recommendations.

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 WFS-0100 (Temperature & Flow Sensor)
• 1 x WPS-0100 (Temperature & Pressure Sensor)
• 4 x EPDM O-rings
• 2 x Dual unions, tailpieces - NPT, sweat, press
• 2 x Flow pipe and tube with connection ttings
• Instruction Manual
Make sure the part number on the unit corresponds to the part number on
the original box
STORAGE
The Sensorlinx™ Heat Meter should be kept in its original shipping carton prior to
installation. In order to retain the warranty coverage it should be stored properly:
• Store within an ambient temperature range of +10ºC to +40ºC
• If possible, store in an air-conditioned environment where the relative humidity is
less than 95%
• Do not store in places where the unit may come into contact with corrosive
gases or liquids
• Do not store in an area or upon an unstable surface where it may become
damaged due to falling

DESCRIPTION AND MAIN PARTS
dEscriPtion
The SensorLinx™ Sensor System is designed to measure and record the thermal energy
used in a residential or commercial heating or cooling system including HVAC, Solar
thermal heating and Geothermal. The sensors can be used individually to track many
system parameter congurations in real time using the HBX ThermoLinx™ App. When
the Sensorlinx™ sensors are used in conjunction within your liquid system, the system
allows for accurate Heat measurement.
SENSOR REPLACEMENT: If one of the sensors fails or must be replaced when
being used in Heat Meter conguration, both the WFS and WPS sensors must
be replaced, as they come pre-paired.
comPonEnts
1. Power Supply Cable: 24V.
2. Wi-Fi Set Button: Press set button to connect to local Wi-Fi network or create local
Wi-Fi connection.
3. NPT Tail Piece: Tailpiece to connect to return/supply piping.
4. Flow Pipe: Composite or Stainless steel option.
5. Sensor Clip: Secure the sensor inside the ow pipe. Clip must be ush with the ow
pipe.
6. EPDM Flat Washer: Washer must be placed inside before installation.
7. Flow Pipe Union: Brass Union
8. Name Plate: Contains sensor Sync-Code

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-0100 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
