Cypress Envirosystems, a division of Cypress Semiconductor Corporation, declared that they have launched a ‘Deadband’ version for their renowned Wireless Pneumatic Thermostat (WPT).
This innovative product with pneumatic thermostats in older buildings will provide autonomous programmable cooling and heating options to save energy. The conventional pneumatic controls used in most of the commercial buildings in the US have only one temperature setpoint and are controlled manually.
According to Marcus Kramer, VP of Engineering, Cypress Envirosystems, the WPT with the deadband version features two independent setpoints; one for heating purpose and the other one for cooling. He explained further that if a heating point is set at 68° F and the cooling at 75° F, the heating option will be switched on automatically when the temperature of the room is lower than 68° F or in the other hand the air cooling will be functional if the room temperature exceeds 75° F. He concluded that heating or cooling will not be automated between these setpoints which enables saving of energy.
The latest buildings are controlled digitally with deadband facility, but till recently the buildings that are pneumatically controlled could not satisfy the energy-saving characteristics. Harry Sim, Cypress Envirosystems’ CEO commented that the deadband version meets all the characteristics of their widely used WPT and could save more energy with the coupling of deadband to the WPT. He added that the system can be installed easily within minutes and ensures a reprisal of 18 months.
Cypress Envirosystems’ WPT system provides direct digital control (DDC) operation within minutes. When compared to the traditional DDC components, the WPT is 80% cost-effective, offers payback within18 months and can be integrated easily within 20 minutes with least harm to the residents. It facilitates temperature remote sensing and setpoint control, night setback and programmable site control, auto-calibration, BACnet installation with the prevailing automations and transmission using the Demand Response programs. The information collected by the sensor employing WPT is deployed in ongoing and retro commissioning to lessen the maintenance expenses and save energy. WPT was launched in 2008 and widely used around 150 sites throughout North America covering universities, K-12 schools, Fortune 500 office buildings, hospitals, and government buildings. The major customers of the product include Santa Clara County Government, Kaiser Permanente, LA Chamber of Commerce and Western Michigan University.
