Dear Sir,
I purchased a GS 501 heater/control from you last year. It is installed and running perfectly. My question is, can the 2 hour filter cycle every 12 hours be reduced to 1 hour? My spa is used about 3 times per week and the cycle is too long and energy wasteful. Is there a software update to change these times?
Thank in advance for your advice,
Brian Foy.
