Circulation Pump Modes
Some spas may be manufactured with Circ Pump settings that allow programming filtration cycle duration. Some circ Modes
are pre-programmed to operate 24 hours a day and are not programmable. Refer to the spa manufacturer’s documentation
for any Circ Mode details.
Purge Cycles
In order to maintain sanitary conditions, as well as protect against freezing, secondary water devices will purge water from
their respective plumbing by running briefly at the beginning of each filter cycle. (Some systems will run a certain number
of purge cycles per day, independent of the number of filter cycles per day. In this case, the purge cycles may not coincide
with the start of the filter cycle.)
If the Filter Cycle 1 duration is set for 24 hours, enabling Filter Cycle 2 will initiate a purge when Filter Cycle 2 is
programmed to begin.
The Meaning of Filter Cycles
1. The heating pump always runs during the filter cycle*
2. In Rest Mode, heating only occurs during the filter cycle
3. Purges happen at the start of each filter cycle
* For example, if your spa is set up for 24/hour circulation except for shutting
off when the water temperature is 3˚F/1.3˚C above the set temperature, that
shutoff does not occur during filter cycles.
