Timer Operation
Immediate Regeneration Timer with Regeneration Day Override Set
When the valve reaches the set Days Since Regeneration Override value, a Regeneration Cycle initiates
immediately. This occurs even if the Volume Remaining display has not reached zero.
Delayed Regeneration Timer with Regeneration Day Override Set
When the timer reaches the set Days Since Regeneration Override value a Regeneration Cycle initiates at
the preset Regeneration Time . This occurs even if the Volume Remaining display has not reached zero.
Timer Operation During Programming
The timer only enters the Program Mode with the timer In Service . While in the Program Mode the timer
continues to operate normally monitoring water usage and keeping all displays up to date. Timer programming
is stored in memory permanently. There is no need for battery backup power.
Timer Operation During A Power Failure
During a power failure all timer displays and programming are stored for use upon power re-application. The
timer retains all values, without loss. The timer is fully inoperative and any calls for regeneration are delayed.
The timer, upon power re-application, resumes normal operation from the point that it was interrupted.
NOTE: An inaccurate Time of Day display may indicate a power outage.
Remote Lockout
The timer does not allow the unit/system to go into Regeneration until the Regeneration Lockout Input signal
to the unit/system is cleared. This requires a contact closure to activate. The recommended gauge wire is 20
with a maximum length of 500 feet. See P4 remote inputs in the wiring diagrams on
pages 16 - 20
.
Remote Signal Start Regeneration
The control valve monitors treated water other than a flow meter. When timer receives a contact closure for the
programmed amount of time, regeneration begins. The recommended gauge wire is 20 with a maximum length
of 500 feet. See P4 remote inputs in the wiring diagrams on
pages 16 - 20 .
Day Override Feature
If the Day Override option is turned on and the valve reaches the set Regeneration Day Override value without
the water meter initiating a Regeneration Cycle , a Regeneration Cycle queues. This occurs regardless of the
remaining volume available.
WARNING
Transformer must be grounded and ground wire must be
terminated to the back plate where grounding label is
located before installation. See instructions for
