TIMER FEATURES

Remote Lock
The timer does not allow the unit/system to go into
Regeneration until the Regeneration Lockout Input signal to the
unit is cleared. This requires a contact closure to activate the
unit. The recommended gauge wire is 16 AWG with a maximum
wire length run of 50 feet.
Regeneration Day Override Feature
If the Day Override option is turned on and the valve reaches
the set Regeneration Day Override value, the Regeneration
Cycle starts if no other unit is in Regeneration. If other units
are in regeneration, it is added to a regeneration queue. This
occurs regardless of the remaining volume available.
Lock Settings (access to Master Programming)
Lock Settings prevents the user from accessing Master
Programming. In Master Programming, select the desired Lock
Settings option (Off, Time Based, Delayed, or Enter Code).
Time Based - User must set clock to 12:01 pm to unlock

for 60 continuous seconds to unlock

Regeneration Types
Softener/Filter Meter Delayed - When volume remaining
reaches zero and the scheduled regeneration time is reached
(default 2 a.m. softener; 12 a.m. filter), the unit will regenerate.
Softener/Filter Meter Immediate - When volume remaining
reaches zero, the unit will regenerate.
Time Clock - Once days remaining reaches zero the unit will
regenerate at the selected regeneration time (default 2 a.m.

Remote Regeneration - Remote Regeneration is accomplished

the remote regeneration input connector. The 3rd party device
