Water Heater Controls


PVI Water Heater Controls

TempTrac electronic operator provides extremely accurate temperature control and fully programmable differentials. It outputs a variable 4 to 20mA signal for those water heater models with modulation. Set point and actual temperatures are displayed constantly on the face of the control. The control also provides a serial connection and Modbus RTU protocol for communication with a building automation system. This connection allows the BAS to "read/write" the setpoint and provides notification of heater status, firing rate and alarm condition. The TempTrac is standard on Conquest, TURBOPOWER 99, TRICON, POWER VT PLUS and MAXIM 3 water heaters. It is optional on almost all other PVI heaters.


PVI Water Heater Controls Gateway

The Dixell electronic operator is an extra-fast-response temperature control for QuickDraw semi-instantaneous water heaters. This device also provides a serial port and Modbus RTU protocol for connection to a BAS.


Custom programmed gateways are available for Building Automation Systems that use Modbus TCP/IP, BacNet or Lonworks communication protocols.
