Help heater temp changes up/down on its own?

[Scubawise]

01) internal heat shows 69 on bmpro set to 72 or higher drops to 71? Moved to 72 and drops to 71? Same with app

02) Put on 72 and went up to 73?

03) Heater bounces up or down on its own?

04) this is on coach battery and battery fully charged
05) 2020 thor vegas 25.6
06) once temp reached it does shut off .but on its own adjusts temp setting up or down 1 degree

Anyone ever seen this?

Call the BMPRO people. They're the experts on their system.

The positioning of the sensors plays a part and how well the air is flowing around the sensor.

I have to make sure my bathroom door doesn’t keep our main sensor covered.

Good idea will call..the sensor may not be the issue when I set to 72 is shows 72 and it goes up or down 1 degree without me touching
