T7 Heating Modes: ‘Standard’ and ‘Economy’
The T7 is set by default to operate in ‘Standard’ heating mode. This means
that when the temperature of the water in the spa drops below the set
temperature, the control automatically start heating, bringing Lo-Speed of
Pump-1 (if there is no 24 hour Circulation Pump) on as necessary. If there
is a Circulation Pump, but control has been set/wired for timed operation,
then the control will automatically bring it on as needed for heat. When the
control is heating, the ‘Heat’ indicator light will be lit, and the display will
fl
ash between the current temperature and ‘HEt’
The T7 can also be set to operate in ‘Economy’ heating mode, where the
heater will only maintain the set temperature when Lo-Speed of Pump-1
is manually activated (if there is no Circulation Pump), or during
fi
ltration
cycles. In ‘Economy’ mode, if the current temperature falls below the set
heat temperature, the ‘Heat’ indicator light will
fl
ash to let you know that
the unit would be heating if not in Economy Mode.
Note:
If you have a Circulation Pump that operates 24 hours a day, economy
mode will not effect heating behavior, and the control will continue to heat
as needed to maintain the set temperature.
T7 Filtration Cycle Operation
By default, the T7 topside will call for the control to
fi
lter the spa a total
of 4 hours a day, split into two
fi
ltration cycles. It is during these
fi
ltration
cycles that the control will run the spa’s ozonator, if one is installed. The
fi
rst 2 hour
fi
ltration cycle will start 1 hour after power is
fi
rst supplied to
the control. It is possible to change the number of
fi
ltration cycles a day
(between 1 or 2), the number of total hours of
fi
ltration a day, and the start
time of the next cycle. When cycling twice a day the next cycle will start 12
hours from the start of the previous cycle, and when cycling once a day
the next cycle will start 24 hours after the previous cycle. Should the unit
lose power, upon reset it will remember the number of
fi
ltration cycles and
duration, but default the start time of the next cycle to 1 hour after power is
restored. During
fi
ltration cycles, the display will
fl
ash between the current
temperature and ‘ ’ to indicate a
fi
ltration cycle is in progress.
