Hi, Pam L!
Thank you for your question. The Delta 144710-SS-I shower unit does have a small diverter in the back of the shower head that changes the water flow from the shower head to the hand shower and also to change to have both on at the same time. The hand shower is the only part of the shower unit that changes settings. This can be changed on the front of the hand shower at the lever. Click to lever to change the settings. The black button in the middle will 'pause' the water coming out of the hand shower. To remove the hand shower from the shower head, first push the wand of the hand shower back, or away from you. This will release the hand shower from the shower head.
As for the temperature coming out in reverse, you will need to shut off the water supply going to the shower unit. Remove the handle and unscrew the bonnet nut to remove the valve cartridge. Once the valve cartridge is removed from the valve body, turn the cartridge 180 degrees and reinstall this into the valve body. Reinstall all other parts. Turn the water back on at the shut off valve and test the water. If you should need further assistance, please contact our Delta Customer Service line at (800)345-3358. We are available Monday-Friday, 7am-7pm, CST and Saturday, 8am-5pm, CST. You may also email at firstname.lastname@example.org.
