Use the Universal Adapter (UA) to connect a thermostat from any vendor to various Johnson Controls® residential communicating systems. The adapter efficiently converts standard 24 V signals to Modbus and sends the signal over a communications harness to the appropriate equipment. The equipment can be an indoor control, an outdoor control, or a ventilator accessory control. The adapter comes embedded with Johnson Controls Smart Equipment controls for a seamless connection to the Mobile Access Portal (MAP) Gateway.
