Installing a timer on a 2008 Sundance Camden (240V 40amp)?

[Keymaster]

Hi all, we’ve been enjoying the heck out of our recently purchased 2008 Sundance Camden spa but I would like to add a timer so I can keep the spa off until a designated time. I’m open to an analog or digital solution and I’m quite handy (able to perform any electrical / install work requires) but I just need to know if/how most people would accomplish this. All ideas are welcome! Please note the tub is currently hard wired to our main panel through a 40 amp breaker (240v). Thanks in advance for any ideas!

WHY? Run an economy mode and have it start the filter cycle 2 hours before the time you want it to be hot. To set start time of filter cycle turn breaker off 2 hours before you want it to be hot. So say you come home everyday at 5 and go in your spa at 6 turn the breaker off then back on at 4 and by the time you go in at 6 it has run a 2 hour filter cycle AND heated the water back up to the set temp if there has been any heat loss during the 10 hours it was not running between filter cycles.

I want to hop in the spa at 5:30am ... and I don’t want to wake up at 3:30am just to turn the thing on 🙂 I’m looking for a timer or ideally a programmable solution. Thanks

Set the filter cycle to start at 3:30. If it is not manually programmable it will start 5 minutes after you turn on power, then again 12 hours later, and so on. So reset power at 3:30 pm and it will start the cycle at 3:30 am and pm everyday.

If you do choose to a a timer, a 240 volt water heater timer should work fine for that.  I have on on my home water heater, from Home Depot.

If you cut power to the pump and heater while the heater us on it will boil the water in the heater damaging pvc, gaskets, and possibly even your heater. If you insist on a manual timer the installation will be complicated and will need a pool timer with a firemans switch. A simple timer will not do.
