I want to bring the temperature of my oil water heater but I can't figure out how... I have a weird aquastat (or temperature control) that has both a high and low limit dial each having 2 needles to adjust. Here is a picture of it. Click here
There is an aluminum and brass needle on each dial. This model is a White-Rodgers controller model# 11C30-14. I checked their website but that model number isn't there.
Can anyone help me adjust the heat setting properly? The water is so hot here that I think its just too much (it will burn you) and I could save oil by turning it down.
