Description

WTL Thermostats

The WTL (Wireless Pneumatic Thermostats

LoRa) Series Wireless Thermostat is a pneumatic

thermostat that retrofits existing pneumatic

thermostats to provide Direct Digital Control

(DDC) such as single zone control functionality at a

fraction of the time and cost, without disturbance to

occupants.

The WTL Thermostat controls the following

equipment:

• Variable air volume (VAV) cooling only

• VAV with hot water

• Hot water radiator

• Induction unit single coil summer/winter

• Induction unit two coils heating or cooling

• Fan coil

• Constant air volume (CAV) with mixing box

• CAV with hot water reheat

The WTL Thermostat is available in the following

direct-acting and reverse-acting models:

• Single setpoint, for cooling only or heating only

applications.

• Dual setpoints, for heating and cooling

applications.

• Summer/winter, for single setpoint control with

summer and winter mode.

Use the WTL Thermostat to remotely monitor the

zone temperature and branch pressure, remotely

control the temperature setpoints, and program the

setback.

You can integrate the WTL Thermostat with

an existing building management system

(BAS) through BACnet

/IP. As a result, the

WTL Thermostat can help save energy through

the implementation of energy savings control

strategies, improve comfort, and reduce the

maintenance cost of the legacy pneumatic HVAC

systems.

All WTL Thermostat models feature a white plastic

cover with the Johnson Controls

logo.

Gateway and Control Server

Use the WTL Gateway to connect WTL Thermostats

to a LoRaWAN

wireless network. Each gateway

creates its own LoRa wireless network. Connect the

gateway to a WTL Control Server for remote control

of WTL Thermostats. One control server pairs with

one gateway. You can map up to 125 thermostats

to one control server. You must use the gateway and control server to connect to a BAS. If you do not want to connect to a BAS, you can use the control server to set schedules. Programmable temperature setbacks The LoRaWAN is a networking protocol designed to wirelessly connect battery operated devices to the Internet. The gateway converts LoRa RF packets into IP packets and IP packets into RF packets. For more information about LoRaWAN, visit https://loraalliance.
