I have an Intellitouch system and want to set two different set of temperatures during the day. The main reason being I do not want the heater (Rayvak) to activate when the pool is in it's normal very low flow mode - I am also using a Intelliflo VF pump so the flow is very low during the day - <15GPM. I believe this has caused me to go through 3 Raypaks in 6 years as the flow is too low and the water gets too hot.
So while I want to activate the heater, it will only be for 3 or 4 hours and during that time I will have the pump run at say 40GPM. I have tested that it is sufficient time to get to the temp I want so that is not the issue.
As I understand (and the way my pool has operated for a few years now) whenever the pool is activated and the temp is too low, the heater is activated regardless of the flow. I can set the flow to increase when the heater is on but then in winter (I keep the pool open 365 days of the year) it would be running at the higher level for most of the time. Given there is no SPA on this system, I seem to think I could use that as the high temp and the pool as the low temp and I am going to try that. However, the manual does not help me too much so I want to make sure I am on the right track.
