I just changed mine today with help from Rheem support as the manual had a typo error.
You should be able to increse to 120 max as default. However if you want to change to 140, you will have to perform the following as detailed in the manual ...
- Turn off the power.
- Remove the cover.
- There is a dip switch on the controller board. Flip dip switch #4 to "ON". Your remotw will start flashing.
- Press SW2 on the controller board for at lease a couple of seconds (The manual states SW1 which is incorrect)
- Flip dip swich #4 back to "OFF"
- close cover
- Turn on heater ... you should be able to adjust up to 140.
