A wireless pneumatic thermostat with direct digital control-like functionality enables automatic zone-by-zone scheduling of temperature set point changes, automatic calibration, and remote monitoring of temperature and pressure. According to the manufacturer, it can be installed in older buildings with legacy pneumatic thermostats where upgrading to a direct digital control HVAC system would require the replacement of existing pneumatic pipes and terminal boxes with electrical actuators and dampers and additional cabling, which is both expensive and disruptive. Building operators have the flexibility to retrofit only selected zones rather than an entire building all at once. The thermostat can operate as a standalone system or can integrate with existing building automation systems such as Siemens, Honeywell, Johnson Controls, and TAC via BACnet. The thermostat has the ability to control and track after-hours HVAC usage, particularly for cost recovery in multitenant buildings.
