Hi - I have a Hotspring hotspot relay, purchased last spring. I have both filter cycles set to 15 min in order to minimize the noise. However, I was wondering if there is a correlation between loss of heat and the length of the filter cycles? = the shorter the filter cycles, the quicker the water gets cold, and as a result, the pumps start now and then to keep the set temperature? Do I understand that correctly? (I am just trying to minimize the noise from the hot tub).
