Thank you for choosing the Wireless Pneumatic Thermostat (WPT) Commissioning App.
This app is intended for use by customers and installers of the Wireless Pneumatic Thermostat system, which is sold by Cypress Envirosystems.
The WPT Commissioning App gives users the ability to create custom CSV files which are needed to commission the Green Box Controller and LoRa gateway to ensure secure wireless communications for the WPTs. Instead of manually typing in the MAC address from each thermostat and the other required fields, the WPT Commissioning App allows the user to scan the QR code or bar code for each thermostat’s MAC address, which will populated automatically. In addition, the other fields such as the node ID, location, description, and BACnet number will be easier to complete.
Once the user completes a CSV file, they can email the file to an email address so that the file can then be uploaded to the Green Box Controller and gateway.
WSTM Payback Calculator2 (years)
1. Orifice diameter should not be confused with pipe diameter. Consult the steam trap manufacturer if orifice size is not known.
2. Calculations are theoretical estimates and actual results will vary. Payback calculation includes avoided lost steam and inspection labor. Benefits from avoided damage resulting from blocked traps are not included in model. The formula used for steam loss in this model is: L=24.24*Pa*D2. Where L=pounds/hour, Pa=Pgauge + Patm , D=orifice diameter. https://www1.eere.energy.gov/manufacturing/tech_deployment/pdfs/steam_pressure_reduction.pdf
3. Actual WSTM installed cost will vary based on volume and integrator.
4. Refers to the manual inspections of steam traps that are currently being done at the facility. The frequency determines the potential avoided failure time when using the WSTM.
5. The frequency and cost of inspection determine the labor savings enabled by the WSTM.
6. The failure rate per year should be based on historical data from the facility. 15-20% failure rates per year are typical. In unmaintained facilities, the failure rate can be much higher: https://www1.eere.energy.gov/femp/pdfs/om_combustion.pdf
