Temp control is only accomplished by moving handle to desired position. If your asking is the hardware that in behind the single lever going to allow for adjustments, then the answer is NO. I installed the same into one of my bathrooms several years ago and I know what I am talking about. The single handle on that type on mine starts off then cold to hot. Problem is I wait for hot water to max so I can adjust it down to a comfortable temperture to prevent being burned. I refuse to buy one for other tubs. The 2 handles make temperture much easier with less wasted water used until its hot. Remember if you decide to replace with a two lever model then you will have to replumb the pipes for a two handle hardware unit (thats the stuff behind wall that your single handle goes into to which is currently plumbed for a single handle hardware unit.)
