Is the spray rinse on a 712 always cold?  I thought the spray rinse was the same temperature as the deep rinse.  I've been in the habit of selecting a warm rinse in order to get the most out of the spray rinse with a higher volume of water (then selecting cold rinse after the spraying has finished), but today I noticed that regardless of whether I selected hot/warm or warm/warm, the spray rinse was cold.
 
Is this normal or is there a problem I need to address?
