Installer and OEM Password Reset Procedures
Should the Installer and/or OEM main access level passwords be lost, password reset is possible, if the reset mechanisms were
enabled by the OEM on the Security page. Refer to
as indicated below. Note that cycling of the valve or user interface power will not defeat this methodology.
NOTES:
• The password reset mechanism simply allows the appropriate user to reset the current password(s) back to the
Honeywell factory default value(s). Once the password(s) are reset, the user can then log in and assign new password(s).
• After reset to the default values, if the passwords are not set to new non-default values, the valve will be in lockout status
and will not be operational unless the appropriate user is logged in. The applicable password(s) must be configured in
order to clear the individual fault code(s). Refer to
– OEM main password not changed fault code 97. Valve will not be operational unless the user is logged in using the
default OEM password.
– OEM reset password feature is enabled and password not changed fault code 102. Valve will not be operational unless
the user is logged in using the default OEM password.
– Installer main password not changed fault code 96. Valve will not be operational unless the user is logged in using
either the default Installer or OEM password.
₀ The OEM can choose to assign the Installer password or allow the Installer to assign it in the field.
