Re: shower too hot
I'm Harvey the Master Plumber.
Your question seems to be how to adjust the temperature of a shower valve?
I'm going to assume this is a single handle faucet. Most are adjustable under the handle. This is the responsibility of the installer but sometimes they forget and you can't get them back. Anyway this requires a little mechanical ability and a few tools.
First be sure to turn off the water to the faucet, then remove the handle (allen wrench or small screw driver). Most have a temp. adjustment ring right there. Simply pull out, rotate and replace. With some you have to remove the sleeve or bonnet under the handle to expose the adjustment fitting. Reasemble and turn on. It is not uncommon to have to do this two or three times before the customer is happy with the setting. The adjustment fittings usually don't have tenp. setting numbers to go by so it might take a few tries.

You haven't provided much information to help narrow down the source of the problem.
Is the flow of both hot and cold water flowing freely? Are the water lines not clogged internally with corrosion or residue? Is it possible that the water is being diverted such as in an apartment building or to an outside spigot (sprinkler system) or kitchen faucets (dishwasher)?
Is your water heater temperature setting correct and is it supplying sufficient hot water flow to the shower?
Do you have a temperature balance cartridge in your shower faucet? If yes, it could possibly be faulty.
u need to adjust the scald protector all single handle units are shipped in cold position for safety reasons if have paper work for handle it explains how to adjust if not unscrew handle and remove on handle / valve stem will see a red and a blue plastic clips pull back clips and turn slightly and push back do this till desired hot and cold setting are to your liking replace handle and your done
Try exchanging the Delta head with one of the other shower heads you are happy with if you haven't already done so. No change in the flow means it's not in the head, and change means it is.
If it is in the head, since you are on a well and not a municiple water supply, you might consider removing the factory install flow controll device located just below the threaded area that mounts to the shower arm. These inserts can be a real bugger on some heads and each one is a little different than the last. The trusty nail often works well.
Your body sprays, I believe, are factory fixed at something like 2.2 gpm and non adjustable.
Also consider for a moment a garden hose with trigger spray head on it. When you squeeze the trigger the water will shoot out a certain maximum distance. If you were to take an ice pick and poke a hole in the hose, that maximum distance will be slightly reduced. The more holes in the hose the less the maximim distance. Correspondingly, the more holes you poke the less distance each hole will squirt because you have the same pressure and volume of water but more exit points.
A monitor has a flow rate of about 6 gpm at 85 psi which is pretty average for shower valves. If your other showers have only one exit point(i.e. one head) and the R1824 has 3 with the same pressure and volume, the garden hose illustration can also explain the volume change as well.
Test: take the shower head off, then run water. If the water can be adjusted to the desired level (hot/cold mix), then the problem is probably in the shower head. Contact the manufacturer of the shower head. If you cannot maintain a good mix, the problem may be in the valve behind the wall or a total house pressure problem---time to get out your wallet and call a plumber.
more than likely you have some debris near the shower head
take an adjustible wrench( crescent or channel lock wrap a rag around the eustaceon( chrome tube coming out of shower wall srap around tube to protect the chrome hold it firmly with vicegrips or channel locks, take adjustible wrench or chanel locks and remove the chrome nut holding the shower head on to the eustaceon(turn counter cockwise be careful not to drop the tools that wil damage the tile or fiberglass
after removing showerhead
turn on shower to force and debris out and place shwoer head into stream of water to clean out any deposits the head may have some type of screen to strain the water
this should work if the flow has not incresed then there is a need to adjust the flow valve at the control
to reinstall the shower head reverse procedure
if you have any teflon tape wrap it around the threaded portion of the eustaceon
