Proton Digitally Controlled Mixing Valve Error Codes
Error codes are displayed on the LCD screen. Errors must be manually cleared by
pressing ENTER and the error condition has been corrected. There are 2 Error Codes on
the Proton Digitally Controlled Mixing Valve. Error codes are listed below:
Error Code 1: Check Probe (Temperature Probe)
This Error indicates that the RTD Temperature Probe installed in the valve outlet is either
disconnected from the Control Box or the wires are broken and it is in need of replacement.
Please verify 3 wire connector on left side of control box is firmly engaged and verify that wires
are continuous to the probe end. Replace if necessary. See Page 8 for details.
Error Code 2: Valve Service Required
This Error indicates that the Proton Valve has reached less than 90% of initial Sweep Value
recorded in Step #10. This translates into lost motion on the shuttle and ultimately loss of ideal
temperature control. The Mechanical Valve Components should be taken apart, cleaned of any
and all debris or scale inside the valve body, inspected and serviced. Worn components must
be replaced if necessary.
