The one Control / MyRV system use a module called the Tank monitor, not only for tank levels but to control the water heater and tank heating pads. Based on what your reporting I would suspect this module to be causing the issue. Check the connections (power, outputs and the 2 CAN bus cables) to be sure that are making solid connections.
