Note:
1. If you are using a lithium battery, you do not need to install this temperature probe,
the probe of the temperature cable should be attached to the surrounding environment
of the lead-acid battery, and the length of this cable is 1.5m, so pay attention to the
distance of battery and SPA.
2.If the cable such as “NTC” (lead-acid battery temperature sensor) cable is not used,
please do not remove the filler plug from the cable support sleeve.
