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).

Yes, it seems that it is availible on our Relay. However on our manual (European version) it says on page 16 that sleep mode is "optional on SX and TX models only" which I understood that it is only availible on the SX and TX models. But I guess that I did not undrestand that correctly? See here: http://www.hotspring.co.uk/sites/default/files/2016-Hot-Spot-50Hz-Owners-Manual-Rev-B-English.pdf (page 16).

Thank you for your reply. But the Sleep Mode is only availible on the SX and TX models, not on the Relay. But I gather that F1 controls the filter cycle for the first 12 hours and F2 for the next 12 hours. So if I set f.ex. F1 to 1 and F2 to 0, then I will have a 1 hour filtering cycle for the first 12 hours of every 24 hour, making it tolerable. Is this a correct understanding of how the filtering controls works?

I purchased a Hotspring Hotspot Relay hot tub last April. It is very nice but our dealer did not stress the noise it makes during filtering cycles. Its ok during the day, but we are having a hard time sleeping as it goes through the filtering cycle every now and then during the night. Does anyone know when/why the filtering cycle starts (is it when the water cools or just on random?) Would it be possible to shorten the filtering cycle period to its minimum to get a good night sleep? Can anyone here help me on this matter? Braola
