The purpose of this post is to document my efforts of conserving as much energy as possible when not using my spa.
I am troubleshooting my control system to determine if it is functioing correctly in ECON mode.
Currently, the control system appears to be working properly as all the controls are working and the heater maintains the proper temperature.
Since I like to use my spa during the winter, I have a rather expensive electric bill. My goal is to reduce the electric bill whenever possible. My local dealer told me that to save power, I should NOT use the ECON mode. He claims that the spa would use more power because the air injector would reduce the temperature of the water resulting in wasted heat and put more load on the heating system.
He claims this was a feature intended for warmer climates. I think otherwise. I think the dealer is clueless about the feature and perhaps the owners manual is lacking good information. My spa is used (came with the house) and was lacking any documentation.
One thing is for sure, in STANDARD mode, the heater runs constantly to maintain the proper temperature against the freezing weather. When the air injector is turned on, it does force cold air into the water and certainly reduces the water temperature.
I will now explore the ECON mode.
I have these questions that need to be answered and are not covered by the owners manual.
1. What is the lowest temperature that the user can select? Currently, I can only set it to a low of 80Â°F (not specified in the manual).
2. How accurate is the control board clock? I have noticed that the FIL cycles do not start exactly when I expect them to.
Twice now, I have discovered the pump and heater to be running when I expected them to be off. I had set the cycle duration to be FIL 1, for a one hour duration. Every 12 hours, I expect to see the pump and heater running for 1 hour then shut down. So, I may or may not have a problem. If the clock is losing time, the FIL cycles may be pushing ahead by as much as an hour a day.
3. If the clock is loosing time, can it be corrected?
Any feedback from other users would be appreciated. Thanks.
