Does this unit require batteries or not? The website states batteries are required, but the spec sheet states batteries are not required.
Does the unit display a numerical temperature as water heats/cools or does the temp dial changed from red to blue as the water heats and cools?
The pictures on the website show that the sensor dial has numbers in it.
Very misleading photo if the dial just displays colors and not numbers in the temp dial.
Thank you for your question!
The batteries are not required, and not needed for this unit, 52646-PK. There is a H2O sensor in the head that will tell the display the temperature.
The display will change colors and show the temperature both on the shower head display.
