III Understanding TightWatt2 Cycles
The TightWatt2 supports up to two start times per day. When the current time reaches a designated start time, a cycle will begin (unless
a cycle is already running).
Cycle Start End | Start Cycle End |
|---- High Speed duration ---------|----------------- Low Speed duration ---------------------------|
|---- Auxiliary duration ---|
At the cycle start time, the high speed pump and auxiliary pump will begin to run. After the high-speed portion of the cycle is complete,
the low-speed portion of the cycle will begin. The cycle is complete when the low-speed portion of the cycle finishes. It should be
understood that the high-speed duration is a value between “Summer Hi” and “Winter Hi” and is dependent upon the time of the year.
Similarly, the low-speed duration is a value between “Summer Low” and “Winter Low” and is dependent up on the time of the year.
The auxiliary run time is a fixed amount and does not vary throughout the year.
Theory of operation: At the cycle start time, the high-speed and auxiliary pump are running to achieve maximum surface cleaning of
the pool. After the pool surfaces have been cleaned and increased the amount of particulates in the pool water, a longer (ultra-efficient)
low-speed cycle runs to remove the particles from the pool water and capture them in the filter media (for a beautiful pool). This
method of cleaning extends the life of your pool equipment and can achieve excellent results - at a minimum cost. The high-speed and
auxiliary run time should be kept to a minimum and most of the water filtration should be done on low-speed to keep your pool looking
great and to keep more money in your wallet!
Mode settings:
The TightWatt2 offers two different operational modes:
Standard: The TightWatt2 controls a primary and auxiliary pump, with the primary pump being either single- or two-speed.
Fireman: This mode allows the TightWatt2 to control a primary pump (either single- or two-speed) and the auxiliary relay provides a
control signal for a heater, commonly called a “fireman’s switch”. When the TightWatt2 is operating in this mode, it will turn the heater
