    How to program WAV during UPS backup

    Have a 90 gallon with two WAVs along with a UPS ... Have the system setup to monitor power and turn off heaters and return pump after power failure lasting more than 5 minutes. The WAVs are powered directly from EB. Would like to program that they would go down to 5% during a power failure of 5 minutes or more. Not sure how to program this.

    Any help ????

    I would not wait to turn off things like your heater. Unless you have a ginormous UPS, you will have drained at least 25% of the batter in those 5 minutes. You are better off turning everything off except your WAVs and then just use the simple statement

    If Power Apex Off 000 Then 5

    to bring them down to 5%

    Zombie:

    A few questions ....
    1. I assume I put the line in the advanced programming section 'buried' in the WAV setup.
    2. How do I code it to return to the usual Schedule after the power returns?
    3. Do I have to put in Fallback and Set commands in the advanced section?

    Thanks John

    Finally another question about the heater during a power outage.

    I have a virtual switch called PowerOutage which is turned On and Off depending the power monitoring. The code is:

    Set OFF
    If Power Apex Off 000 Then ON
    Defer 001:00 Then ON

    There is a short Defer on the ON to assure the power outage is not just a flicker.

    I then use the switch to turn off the heater, return pump etc. In the case of the heater the code is:

    Fallback OFF
    If Temp < 76.0 Then ON
    If Temp > 78.0 Then OFF
    If Output PowerOutage = ON Then OFF

    How do I get it to return to normal control when the power returns. When power returns now ... the heater is turned ON not returned to the previous state.

    Thanks again

    John

    PS I reduced the defer to 1 minute after reading your comments. May reduce it further to 30 seconds.

    1. In the advanced tab yes.

    2. As soon as the power is restored all programming will resume automatically

    3. No
