Model 150 Boiler Controller

The Model 150 uses the latest in microprocessor capability, giving the user a high level of application flexibility. Multiple inputs and very easy setup characterize this new technology.

This controller can be used in the Continuous Sample, Sample/Cycle, or Sample/Hold modes to control the boiler water conductivity.

Features

  • Use this Controller for conductivity control of boilers. It can be used for Continuous Sample, Sample/Cycle, or Sample/Hold control of boiler conductivity.

  • Removable power cord and receptacles for simple conduit installations.

  • One (1) water meter input, conductivity input, flow switch input, and 4-20 mA output are all standard features.

  • Designed with a single circuit board for better reliability and lower cost.

  • Large open shallow enclosure for easy wiring.

  • The enclosure is rated NEMA 4X.

  • Power selector switch for 115 or 230 vac operation.

  • Heavy-duty stainless steel domed numeric keypad and illuminated graphical display allow for quick and easy programming. Steel domed switches improve the tactile sensing and life expectancy of the keypad.

  • LED indicators for power, alarm and relay status.

  • The display is lit by two LEDs when any key is pressed.

    • Easy to program, the Model 150 Controller uses an intuitive menu and a numeric keypad for programming.

    • No add-on options. Flow switch input, 4-20mA output, and three boiler conductivity control methods; Continuous Sample, Sample/Cycle, and Sample/Hold are standard.

    • Single circuit board design improves reliability.

    • Multiple methods of chemical feed for application flexibility.
