Hayward omni logic Heater Set point sensitivity

[sterfry1988]

We have noticed that our Hayward heater in Spa mode with Set point to 98 degrees will drop down to 95-94 degrees (as reported by Omni logic) before kicking back on.

Is there a way to adjust the sensitivity so that it will turn back on? In some instances we find ourselves manually toggling the Heat from on to off to try and kick start this process. Sometimes it works but we can't reproduce it.

What temperature is the heater set to?

Does the heater temperature readout match the actual water temperature?

Is the remote a two-wire connection?

Does the display show "bo"?

Try taking the heater out of bypass operation (BO) and see if it runs correctly and shows the correct temperature.

Yes to bo, set point is 98. Not sure if the remote is a two wire connection it's all controlled through the omni logic app. The heater heats to the proper temp (98) but then it will drop ~5 degrees before kicking back on. My Raypack heater would kick on much quicker.

If the heater is set up as a "Solar" heater, then that might cause the problem.
