Pneumatic to Direct Digital Control DDC Room Thermostats

Pneumatic to Direct Digital Control DDC Room Thermostats

The WT-4000 has been discontinued, check out the WTL for Digital Pneumatic and like-for-like replacement Thermostat needs.

Product Overview

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.

Features

  • Pneumatic-to-DDC piezoelectric air valve — eliminates the need for mechanical calibration; provides longer, more dependable, and maintenance-free operation
  • Wireless RF communications — provides real-time status for proper room thermostat operation; centrally automates the building temperature control system; reduces installation time and costs
  • Stand-alone capability — allows the room thermostat to be configured in the field for stand-alone applications.
  • Optional WT-ROUTER Router — enhances the wireless mesh network by extending the range of the network; provides multiple routes of communication with the WT-BAC-IP Gateway
  • Easily applicable data types — allows transmission of the sensed temperature, setpoint temperature, occupancy status, and low battery conditions to the associated WT-ROUTER Router and WT-BAC-IP Gateway
  • Programmable temperature control schedule — maximizes energy savings without sacrificing occupancy comfort
  • Two-pipe, direct acting/reverse acting (DA/RA) dual control action — allows replacement of a wide variety of existing pneumatic room thermostats
  • Motion sensor input (WT-4002-MCM and WT-4002-MFM models) — maximizes up to 30% energy savings in high-energy usage environments; facilitates trending of floor space usage
  • Liquid crystal display — provides an intuitive user experience, with real-time indication of control system and room conditions
 

Recycling Program

Johnson Controls supports and sponsors thermostat recycling programs in the U.S. and Canada. We are a member of the Thermostat Recycling Corporation (TRC), a not-for profit organization that facilites the collection and proper disposal of mercury-containing thermostats in the United States. TRC maintains a network of more than 3,400 collection sites nationwide. To find a collection point in your area, go to thermostat-recycle.org and enter your zip code.
