The WT-4000 Series Pneumatic-to-Direct Digital Control (DDC) Room Thermostats provide reliable zone comfort and enhanced energy economy via remote monitoring and temperature setpoint management. This arrangement provides greater energy policy compliance, and facilitates trending of floor space usage in commercial, industrial, and municipal HVAC environments.
The WT-4000 Series Room Thermostats are ideally suited for energy-saving, pneumatic-to-DDC building upgrades. Designed for non-invasive replacement of existing manual pneumatic thermostats, the WT-4000 Series Room Thermostats provide a number of DDC features, including remote wireless setpoint control and occupancy scheduling, and continuous room temperature, branch line pressure, and battery status monitoring. All of these features were previously unavailable in existing pneumatic HVAC control systems.
