will all three of these play nice together? i have a hayward 2hp, 2spd pump on a ps8 with a hayward 400k btu heater. when the pool crew originally came out to get it started, they only hooked up the single high speed and everything was working pretty good. used the spa, and when i went to shut off the pump, it forced itself into "cooldown mode", where it shut the heater off and kept itself running for a few minutes.
since then, they got the low speed running as well, but now when i hit the filter button, since it has to cycle through "hi, low, off", the heater never shuts down and the cooldown never kicks in. is there a way to make tis work right? the manual for the ps8 never seems to address this situation.
