User Screens Home Screen: Current outlet temperature and Set point temperature Home Screen: After initial “Full Sweep” the bottom line of the digital display indicates the measured sweep value of the valve, hot to cold. Please record this numerical value as you will need it for calibration Screen 2 below. If you “miss” the “full sweep” number simply unplug the unit and plug back in and the unit will do another sweep and give you the value.

Menu Screen 1: Main Power Supply Pressing ▼ 1 time displays POWER: 12.82 This indicates the input supply voltage to the main control board, Volts DC, and should always be at least 12 VDC Menu Screen 2: Firmware Revision Pressing ▼ 2 times displays FW Rev: X.X.X.X This screen shows the current version of Firmware loaded into the Proton processor. It may be used for reference and troubleshooting.

Calibration Screen 2: Full Valve Sweep Counts The above Calibration Screen is used to enter the initial Full Valve Sweep Value obtained and recorded in Step #10 from initial power up. Press ENTER to input FVS value, it will flash. Use ▲ button to adjust FVS counts value and advance until it agrees with the Initial Sweep Value recorded in Step #10 above. Press ENTER to save the FVS counts value. To Exit Calibration: Press the ▲▼buttons simultaneously.

SENSOR TROUBLESHOOTING AND REPLACEMENT When a sensor is disconnected or no longer in proper working condition, an error message is displayed on the controller Err: Check Probe See Error Code 1 above. TURN OFF POWER TO THE PROTON CONTROL BOX BEFORE TROUBLESHOOTING OR REPLACING ANY WIRES AND SENSORS. Determine if the sensor is truly broken and not a simple disconnection. Please verify the 3wire RTD Temperature Probe connector is firmly plugged into its location on the bottom left of the Proton Control Box.

INSTALLING AND REPLACING TEMPERATURE PROBES The RTD temperature probes used with Proton assemblies are simple to install. On the valve body the temperature probe is connected to the valve with a ¼” MNPT x ⅛”compression fitting. Teflon tape and a small amount of thread sealant should be used on the NPT side of the fittings. The ferrule, installed with the cone facing down, then sits on the top of the compression inlet.

REQUIRED PIPING METHOD W NOTE: FOR MULTIPLE TEMPERED LOOPS, A BALANCING VALVE AND CHECK VALVE MUST BE INSTALLED ON EACH LOOP AFTER TEMPERED FIXTURES Leonard Proton Digital Mixing Valves are simple in design and may be easily cleaned, adjusted and repaired. If the installation is accessible, servicing may be completed without disconnecting the valves. NOTE: Leonard Proton Digital Mixing Valves must be regularly maintained to provide best performance.
