Flow based Feed
should be selected if the relay will be triggered to activate for a programmable
amount of time after a given volume of water has passed by the flow meter. In the relay menu, the
volume to trigger feed, and the amount of time of the feed will be specified.
Feed With Another Relay
should be selected if you want to activate this relay at the same time as
another relay (for example, inhibitor feed and bleed).
Feed After Another Relay (%)
should be selected if you want to activate this relay after another
relay has finished its activation cycle (for example, inhibitor feed after bleed). This relay will
activate for a percentage of the time that the other relay was active.
Feed After Another Relay (Fixed Time)
should be selected if you want to activate this relay after
another relay has finished its activation cycle (for example, inhibitor feed after bleed). This relay
will activate for a programmable amount of time.
Feed as % Time
should be selected be selected to activate the relay for a given percentage of a
user-specified time period.
Spike Set Point 1 Week Cycle
should be selected to activate the relay based on one set point for a
majority of the time, and then spiking the concentration for a programmable amount of time, as
often as once per day, on a weekly schedule. This is typically an oxidizer addition based on an
ORP electrode.
Spike Set Point 2 Week Cycle
should be selected to activate the relay based on one set point for a
majority of the time, and then spiking the concentration for a programmable amount of time, as
often as once per day, on a bi-weekly schedule. This is typically an oxidizer addition based on an
ORP electrode.
Spike Set Point 4 Week Cycle
should be selected to activate the relay based on one set point for a
majority of the time, and then spiking the concentration for a programmable amount of time, as
often as once per day, on a monthly schedule. This is typically an oxidizer addition based on an
ORP electrode.
Daily Biocide Timer
should be selected if the relay will be activated up to 10 times per day, every
day, at a programmed time of day, for a programmed amount of time. In the relay menu, you will
specify the time of day for the relay to activate, as well as the amount of time it will be activated.
1 Week Biocide Timer
should be selected if the relay will be activated on a schedule that is the
same every week. In the relay menu, you will specify the day of the week and the time of day for
the relay to activate, as well as the duration of the activation. The relay can activate only once per
day.
2 Week Biocide Timer
is identical to the weekly timer, except the schedule will repeat in a two-
week cycle.
4 Week Biocide Timer
is identical to the weekly timer, except the schedule will repeat every four
weeks.
Dispersant
should be selected to activate the relay for a fixed time either before or after a biocide
addition.
Bleed Volume based on Makeup Volume
should be selected if the relay will be triggered to
activate by a volume of makeup water, and will be deactivated by a volume of bleed. Note that
flow meters must be installed on both the bleed and the makeup lines to use this mode.
