by AF 0924 e3 — September 26, 2008—Cypress Envirosystems, a subsidiary of Cypress Semiconductor Corp., has introduced a wireless pneumatic thermostat (WPT) to reduce energy consumption and maintenance costs in older buildings with legacy HVAC systems.
The Cypress Envirosystems WPT can be installed in minutes with no disruption to existing systems, says the company. It enables automatic zone-by-zone scheduling of temperature setpoint changes, automatic calibration, and remote monitoring of temperature and pressure.
The retrofit solution allows building operators to change from legacy pneumatic thermostats to digital functionality in minutes.
Legacy pneumatic thermostats require manual setpoint control and calibration, resulting in costly maintenance and wasted heating and air conditioning of unoccupied areas, according to Cypress.
Until now, these shortcomings could only be overcome via expensive, disruptive and time-consuming replacement of the pneumatic system with a Direct Digital Control (DDC) HVAC system. DDC retrofits require the replacement of existing pneumatic pipes and terminal boxes with electrical actuators and dampers and additional cabling at a minimum cost of $2,000 per zone. The Cypress Envirosystems WPT can be installed for about $400 per zone.
