2.7.g. 28-Day Timer
Each 28-Day timer has Program 1-4 for programming the various feed times. While the programming steps
for four programs are the same, each can have its own independent settings.
BLEED LOCK - How long to lock out the bleed function after the timer's run time starts.
FLOW LOCK - 3 selections if a system has a flow switch:
• Only With Flow - If there is no flow at the start time no feed occurs.
• With or Without Flow - Feed occurs regardless of flow condition.
• Flow Only/Store1 - If there is no flow at the start time, one run cycle will occur when
flow does come on. Only one run will occur regardless of how many more than 1 are
missed due to no flow.
NOTE: ORP lock is only for systems with the ORP function. If interlocked, the ORP setpoint will switch to
the 2nd setpoint for control during the timer's programmed RUN time. The feed device must be connected
to a relay activated by the ORP setpoint/control function.
