Please read the following instructions carefully before downloading your software.
To make sure that the W100 upgrade is appropriate, go to the Configuration Settings menu, scroll to Controller Details, enter, look at the Product Name and only use an upgrade file that matches the Product Name. To determine the software revision on your controller, go to the Configuration Settings menu, scroll to Controller Details, enter, and scroll down to the Control Board Software version.The latest version is 3.31. Do not perform this upgrade unless the version on your controller is 1.11 or higher.
Upgrading the software on your W100 controller is easy! All you need is a 32MB or larger USB flash drive. (Please note: 16GB is the maximum supported size)
Always upgrade to the latest version for the greatest reliability! We are continuously improving the W100 and P100! Here are the features we have included lately. Please note that if you have an early revision of the software, you may only update to the latest revision, not to any intermediate revision.
Added On Delay and Off Delay settings for relays using Alarm Control Mode
Added Alarm Suppression based on the state of Digital Inputs
Added Korean language support
New logarithmic generic sensor type for use with Ion Selective Electrodes
Improved anti-windup in PID control modes
Added two decimal places to Flow Proportional control mode set point to allow for smaller values
Modified Time Proportional and % Timer control modes so that set point changes take effect immediately instead of at the next time cycle
Improved response time when using a duty cycle in On/Off control mode
Fixed an issue where the controller doesn’t resume control in intermittent sampling if a calibration is started but never completed
Fixed an issue where using the Smoothing Factor for disinfection or pH/ORP causes an offset in the reading.
Fixed an issue where custom names for I/O in Asian languages could not be accomplished.
Immediately show new conductivity value after a calibration when using Intermittent Sampling
Add high and low alarms for Paddlewheels
Can now read temperature sensors even if the primary sensor is disabled
Analog outputs forced to 0 mA during the boot up period
Fixed an issue where Hand and Auto Output Timeouts interacted
Adds Flow Proportional control mode using a paddlewheel flow input and analog output
Fixed an issue where the pulse proportional control pulse rate could be twice the expected rate.
Fixed an issue where the conductivity reading displayed is not updated immediately following boiler intermittent sampling if trapped sampling is disabled.
Fixed an issue where resuming control is delayed for several seconds after a biocide bleed lockout or probe wash hold time of 0.
Adds support for:
The feature where a biocide or timer event can be selected to occur immediately after an interlock clears has been re-named from “Interlock Delay” to “Add Last Missed”
Conductivity-based biocide prebleeds will now be forced to have a time limit also associated, so it’s no longer possible for the prebleed to last forever
Added an Air Calibration for contacting conductivity sensors to improve accuracy
Modified the % Timer algorithm so that a new cycle starts if the sample period setting is changed
Increased the maximum setting allowed for the paddlewheel K factor
Fixed an issue in Timer control mode Hourly event repetition settings changing after a restart
Fixed an issue where a Flow Timer control output can stop accumulating feed time if interlocked by another output
Fixed an issue with PID control mode if the input is paddlewheel or virtual input type
Adds support for:
PID control using Pulse or Analog outputs
Intermittent Sampling for boilers without using a trapped sample
Added a 2nd flowmeter input to the Feed Timer control algorithm
Ability to set the flow total to match the meter’s register
Antimony pH sensor support
Ability to restore default settings
Chinese and Taiwanese languages
Modified Bleed/Feed and % Timer algorithms so a feed cycle doesn’t begin immediately after and interlock clears
Ability to choose to feed the last missed Biocide after an interlock
Improved system stability
Improved sensor speed of response
Adds support for:
Control based on paddlewheel flowrate
Duty cycle with on/off control mode
Easier biocide, industrial timer and probe wash programming
Automatic reset of flow total (daily, monthly, annually)
Totalize time that a digital input (like a flow switch) has been open or closed
Delay alarm notifications on system startup
Fixed pulse proportional control output going below the minimum setting
Reduced low limit for temperature sensors to -20 C, -4 F
Disabled the Home screen timeout during log file transfers
Adds support for:
Automatic buffer recognition for pH calibration
Three point buffer calibration for pH sensors
Probe wash relay control mode
Damping/averaging on sensor inputs
User-adjustable conductivity automatic temperature compensation %
More flexible alarm relay control mode, able to select specific groups of alarms that trigger the relay
Adjustable display contrast
Increase paddlewheel rate to 500 Hz.
Improvements to intermittent sampling calibration, and calibrations in general
Reset default calibration
Suppress sensor alarms during No Flow
Adds support for a Generic type disinfection sensor. Adds the ability to change between a general industrial and a cooling tower/boiler controller with the Show HVAC Modes menu. Adds Japanese language support. Adds the Minimum Relay Cycle feature for use with motorized ball valves, allowing the valve time to fully open and close. Adds User Configuration File import and export to quickly save and change set points. Changes the way the Security (access code) menu is structured. Adds the sensor Raw Value to the list of items that can be on the Home display. Adds the current day of the week to the Details screen for Biocide Timer and Timer control modes. Adds a menu to cancel the remaining feed time when using Bleed Then Feed control mode.
Version 1.19 (First release for P100)
Prevents a critical file system issue from occurring. It is highly recommended that all controllers be upgraded to v1.19 or higher.
Eliminates a situation where the general industrial timer control algorithms don’t know when the clock has been changed and don’t activate on schedule. Changes how the passive pH calibration decides the signal is stable enough to continue.
Adds support for Spanish and Portuguese languages. Improves the accuracy of the temperature measurement. Standardizes the range of certain timed events as 00:00:10 to 23:59:59 (In HH:MM:SS format).
Click a link above to Download the software upgrade. A dialog box will open, asking if you want to save or open the file. Choose “Save As”. In XP and Vista, save it to your desktop (this makes it easy to find). In Windows 7, 8 or 10 the file is saved in your “Downloads” folder.
In XP and Vista, double click the file on your desktop to unzip the file. In Windows 7, 8 or 10, go to your Downloads folder and extract the file (you will normally have to right click on the file and select “Extract All ”). Drag the extracted upgrade file to your desktop.
Plug in your USB flash drive. The drive window should open. If not, go to “My Computer”, and open it (should be “Removable Media” drive).
Drag the file named WxxW100-v3_31.bag to the USB drive. (Make sure that the Upgrade file is the only file on the drive.)
Unplug the USB flash drive from the computer. Now you can upload it to your controller.
