WTL-PD2-00 Johnson Controls Thermostat

Overview

The Johnson Controls WTL-PD2-00 is a wireless pneumatic, direct-acting two-pipe deadband thermostat from the WTL (Wireless Pneumatic Thermostats LoRa) Series. It is engineered to retrofit existing pneumatic thermostats, providing Direct Digital Control (DDC) functionality at a fraction of the time and cost without disturbing occupants. By combining pneumatic control with wireless LoRa communication, it allows integration into building management systems (BAS) via BACnet/IP to remotely monitor zone temperatures and branch pressures.

Features

• Wireless pneumatic two-pipe dual-action design supporting separate setpoints for heating and cooling with an adjustable deadband.
• Retrofits legacy pneumatic systems to provide DDC-like functionality, such as remote setpoint control and setback programming.
• Eliminates hardwired signal runs, reducing installation time and costs.
• Integrates with building automation systems through BACnet/IP.
• Includes a white plastic cover with the Johnson Controls logo.

Specifications

• Action: Direct Acting
• Setpoint Range: 55°F to 85°F (13°C to 29°C)
• Temperature Differential: 32°F to 122°F (0°C to 50°C)
• Air Consumption: 0.011 SCFM
• Maximum Pressure: 25 PSI
• Power Supply: Battery included (minimum 2-year battery life)

Applications

• Well-suited for commercial office buildings, schools, hospitals, and institutional facilities utilizing pneumatic HVAC controls.
• Controls equipment including variable air volume (VAV) cooling only, VAV with hot water, hot water radiators, fan coils, induction units, and constant air volume (CAV) systems.
• Ideal for retrofit and renovation projects where running new thermostat wiring is impractical or cost-prohibitive.
