Wireless Pneumatic Thermostats

GPG-020, March 2015

The wireless pneumatic thermostat (WPT) is a new technology that can be retrofitted to an existing pneumatic control system. WPTs give conventional pneumatic controls the energy-conserving functionality of more contemporary control systems, such as direct digital controls (DDC), but at a fraction of the cost.Click on the infographic below to enlarge.

GPG Findings 020, March 2015, WIRELESS PNEUMATIC THERMOSTATS. Opportunity: Where are pneumatic thermostats typically found?
