New DHT Controller
The DHT state of the art control system offers unmatched performance and full user configurability for water heater applications. It features a durable temperature sensor transmitting a millivolt signal through quality twisted shielded wiring. The signal transmits directly into the advanced PID controller, which in turn sends a signal to the electrically activated fully modulating and fast acting three-way control valve with high turndown to achieve accurate temperature control over various demand situations. The control valve can also be configured for straight through two-way operation when used with VFD pumps.
Standard Features:
- 4.3 HMI Touchscreen
- Feedforward Logic Controller includes 1/8 DIN with LCD display (back-up interface)
- Boiler Water Inlet and Outlet Temp Sensors (optional)
- Fault Log
- Trending/Graphing
- RS485 MODBUS® Data Port
- Compatibility with Modbus and BacNet BAS system standard without the need for external gateway.
- Optional gateway is available for all other protocols
- Ethernet connection
- Data Logging
- Remote Monitoring: Through Ethernet Connection
