Averill Park, NY August 24, 2016 -- All Intellifaucet D & E Series mixing valves are now shipping with a new logic board. The new board features:

  • Faster response for improved temperature control
  • Proportional opening for faster temperature lock-in
  • 100% compatible with all Intellifaucet D & E Series valves

We're introducing yet another new logic board. This board uses an 8MHz processor with built-in 10 bit AD conversion to give our D and E series Intellifaucets faster response and better overall performance.

The PN for the new board is 11320.



Averill Park, NY July 1, 2016 -- We are now shipping all Intellifaucets with a new logic board. The new board features:

  • Presets for temperature, flow, timer or batch quantity
  • Front panel calibration
  • One board for all Intellifaucets
  • Faster lock-in for better temperature control
  • Front panel flowmeter calibration for batch models
  • Wider temperature range
  • Jumper on board to disable beeper
  • 100% compatible with all Intellifaucets

We're pleased to introduce our newest Intellifaucet logic board. Using a powerful Atmel microcontroller, we're able to offer better performance, new feautures, higher reliability and 100% compatibility with all Intellifaucets we've ever made.

The EEPROM memory allows us to offer custom presets for many variables. For example, by pressing and holding the Show Temp Setpoint button for 3 seconds you can lock in the current setpoint temperature as a preset that will remain even after cycling power. You can update the preset as often as you like, at any time. Presets are available for temperature, flow, timer or batch, F/C, Metric/English, Weight/Volume, if applicable.

You no longer have to remove the cover to perform temperature calibration. By pressing and holding the STOP button for 3 seconds, you enter calibration mode. Then, the Flow and Timer/Batch keys change the gain and offset values for temperature calibration. Press and hold the STOP key again to lock in the calibration settings. Like always, all Intellifaucets are calibrated at the factory and rarely need re-calibration.

Our new board can be setup for all 4 sizes of Intellifaucets, K, RK and Batch models, simply by pressing and holding certain keys on the keypad. This is done at the factory, and rarely needs to be changed in the field. If however, you need to swap an RK250 board into an RK750 Intellifaucet, you can do so without ordering a special EPROM chip as in the old boards.

We have a new algorithm that locks in the water temperature faster after you press the START button. In one case, we reduced the lock-in time on an Intellifaucet RK750 from 17 seconds to 6 seconds (after hot and cold water were up to the unit).

You can now calibrate flowmeters for Batch units from the front panel instead of calibrating the flowmeter itself. This allows for much more precise batches.

All Intellifaucets now have a 32F - 203F temperature range. There is no need to order the special high temperature versions of our program.

You can now disable the beeper by removing a jumper on the board. This is valuable for customers who work in quiet environments.

The new board is 100% compatible with all Intellifaucets we've ever made. The remote connectors have the same pinouts and functions. You will notice a slightly brighter display, and slightly smoother operation when compared to the old boards. The new boards will be more reliable since there are fewer components on the board.

All new Intellifaucets are shipping with the new board. You can order the board separately to replace boards that have been damaged. Please specify what Intellifaucet the board will be used in and we'll set it up for you, or you can set it up in the field. The PN for the new board is 11318.




Averill Park, NY March 29, 2016 -- We are now shipping ECVs with a new logic board. The new ECV board has:

  • Higher resolution for smoother control
  • Adaptive noise filter dynamically eliminates dithering
  • Switch options for isolated/grounded control signal and more

Our new microcontroller has a 10 bit AD converter instead of an 8 bit converter for a 4X improvement in resolution, from 1/2 percent to 1/8 percent.

We improved our digital noise filter by introducting an adaptive filter. Every second, the filter measures the dither of the valve and adjusts the filter parameters until the dithering is eliminated. To reset the filter, simply cycle power. A switch on the board turns off the adaptive filter, leaving a mild digital filter in place.

The new boards are 100% compatible with all ECV valves and are drop in replacements. The boards are also available as a spare part, PN 11299.

Please contact us if you have any questions.

How to Buy

You can place your order online using our secure, online ordering system, or by calling, faxing or mailing in your order, whichever you prefer.


US Shipping Charges (worst case - see below)

Ground: $10.42 + $0.88/lb
Second Day: $26.42 + $4.17/lb
Next Day: $66.57 + $4.84/lb

Ground service takes 5-7 business days to California and the West Coast, 2-3 days to the South and Midwest, and 1-2 days to the Northeast.

The shipping formulas above are based on shipping to California from our New York factory. Shipping charges to destinations closer to us may be as little as one-half the calculated charge. After receiving your order, we will calculate exact shipping charges and send you the corrected order total. Shipping charges change weekly with volatile fuel prices and associated fuel surcharges.
