Cypress Wireless Pneumatic Thermostat Overview

Cypress Wireless Pneumatic Thermostat Overview

The worldwide, patent pending Wireless Pneumatic Thermostat (WPT) delivers DDC-like functionality at a fraction of the time and cost of existing legacy systems. The WPT is installed without the need to change out pneumatic pipes, run wires, replace actuators or disturb tenants. It is not necessary to upgrade entire building at one time; installers may selectively retrofit individual thermostats for incremental benefits.

Cypress Envirosystems (Cypress) delivers high-performance, mixed-signal, programmable solutions that provide customers with rapid time-to-market and exceptional system value. Cypress’ offerings include the PSoC® programmable system-on-chip, USB controllers and general-purpose programmable clocks and memories. Cypress also offers wired and wireless connectivity technologies ranging from its CyFi™ Low-Power RF solution, to West Bridge® and EZ-USB® FX2LP controllers that enhance connectivity and performance in multimedia handsets. Cypress serves numerous markets including consumer, computation, data communications, automotive and industrial.

Conventional retrofits of pneumatic controls to DDC typically cost over $2,500 per zone and causes significant disruption to building tenants. The long investment payback (usually four to seven years) and the need to wait for tenants to vacate mean that most legacy buildings never upgrade despite compelling energy and productivity savings.

The new Cypress WPT accomplishes the same retrofit in less than 20 minutes, for less than 20% of the cost of conventional DDC. This means that retrofits can be performed right away, even while a building is fully occupied, and achieve payback periods of about one year. These are key advantages for stimulus funding eligibility.

The WPT is directly compatible with the majority of legacy pneumatic thermostats from Honeywell, Johnson Controls, Robertshaw, and Siemens. It can seamlessly integrate with modern building automation systems from virtually all major vendors via BACnet/IP. Numerous 3rd party systems integrators have successfully implemented the BACnet link including Emcor, ACCO, Johnson Controls, Siemens, RSD-Total Control, Wolf Mechanical, Syserco and others.

In addition, the system has completed compatibility testing with utility Auto-Demand Response systems, developed by Lawrence Berkeley National Laboratories, and is being used by California utilities to shed electrical load during peak consumption periods.

According to Dan Ginn, General Manager of RSD-Total Controls, a distributor and installer for the WPT, “In today’s challenging business environment, this technology can be a savior to help us implement projects that are otherwise economically unfeasible.”

“The Wireless Pneumatic Thermostat will help unlock an enormous reservoir of potential energy savings from legacy facilities, including older federal buildings,” said Bien Irace, Senior Vice President of Business Development for Cypress Envirosystems.

Strengths:

  • Integrates into current BMS platforms with standard protocols
  • Installation time is minimal; Building shutdown not required
  • Makes utility programs such as DR more viable

Weaknesses:

  • Functionality is only as viable as the pneumatic system it is being connected with.
