General Description
The 24 VAC Disio Display thermostat is a thermostat/controller designed to provide control for the following 3 main applications:
- Reheat (DX – 50)
- Pressure Dependent Damper Control (DX – 1XX)
- Fan Coil (2 pipe and 4 pipe) (DX – 3XX)
The Disio Display thermostat works as a standalone control thermostat. Disio Display thermostats ordered with optional BACnet can be connected to a BACnet network through its native BACnet MS/TP connection for remote control and monitoring. A USB-C jack on the bottom of the controller allows connection to a Windows based laptop for easy onsite configuration and monitoring using the free Disio Setup software. Download the Disio Setup software for Windows computers at disio.io/setup/.
