The BRADFORD WHITE Water Heater Controller is a microprocessor based, state-of-the-art,
device offering unmatched performance and full user configurability through LCD interface for
water heating applications.
It is used with type ‘J’ thermocouple sensor.
Menu based programming, all parameters and setpoints are user configurable via menu
prompts. All aspects of the unit are user configurable through the interface on PID controller
display.
Utilizes 1/8 DIN advanced programmable PID temperature controller factory configured for full
range of math, logic, totalizer and specialized functions required for single loop process and
temperature control of water heating applications.
MODBUS RTU: RS485Network allows single or multiple units to be connected together for
distributed applications, remote monitoring SCADA applications (optional).
MODBUS TCP/IP and BACnet UDP/IP: Ethernet Network allows single or multiple units to be
connected for distributed applications, remote monitoring SCADA applications (optional).
Ethernet port is available on the rear side of the temperature controller.
Optional building automation communication gateway is also available for connections with
