SWCG vs Heater pump run time, Timer, Small Pool (~1,500 gal)

[ATM]

I may be overthinking this, but I'm wondering what to do if you need more pump run time for the heater than you do for the SWG? Without over-chlorinating our pool?

I'm thinking with how small ours is (1,600 gal), the pump may need to run a lot longer to heat in the cooler months than what is required to chlorinate the pool with a SWCG (even at a low setting)... e.g for 1,600 gallon pool, the CircuPool UL-25 at 5% creates 1ppm FC in just 5 hrs, but say the heater is calling the pump on & off 8-12 hrs throughout the day to heat/maintain heat for the pool, but that would create too much chlorine.

I've read here & understand we should put the SWCG on a timer for safety reasons. This may help with our "over-chlorination" problem too... but I'm having a hard time understanding how to pull off a system like this. I think what would be ideal is to have a timer for the SWCG & pump on for X hours in the morning to chlorinate (say 2 hours?) & then tell the SWCG not to come on again until the next day but still allow the heat pump to call the pump on to heat the pool?

Any feedback is greatly appreciated.

Yes, you get two timers running each according to your needs

What if the heat pump calls the pump on based on temperature (not time) like a thermostat? Does that make sense?

(Thank you for your response & making a new thread Wireform. I just realized after hitting reply.)

@ajw22 Do you have any input on how to achieve this setup or any input on what would work best? You've been helpful in other similar threads.

You have two levers to adjust daily SWG chlorination - run time and %.

You need to do the dance of balancing the two as the heating season changes.

You will have a minimum pump runtime for skimming and pool cleaning whether your heater is running or not. Generate your daily FC need during that time.

With a two timers setup you have the controls. Rather then playing what if, just set it up and figure it out.
