triple aquastat HELP

Hey everyone, hoping someone can help me out here

I have a peerless oil fired boiler and a becket burner with a year old honeywell aquastat..

my question is very basic but i cant seem to find the answer...

----I have completely seperate gas fired hot water tank for everything else in my home---

question is, my high is set at 190 and low is set at 170......the burner clicks on every 5 minutes with or without a call for heat, what is the point of having a "low" setting when I dont need the water temp to be hot and ready for a shower etc etc........? I can only imagine how much oil is being wasted keeping the system hot while my woodstove is heating most of my home

For starters, turn the darn thing DOWN!

There's no reason at all for the HIGH to be at 190... turn it down to 180.

The LOW setting is intended to keep the boiler warm for domestic hot water use... so there is no reason at all to have that set at 170 if you have a separate water heater for domestic.

Give us some history... how long has it been like this? Tell us everything you know about the boiler's history.

How long has the separate water heater been there?

In the meantime, turn the LOW setting DOWN to like 130-140 for the time being until we can get more information from ya and figure it out.

Some more questions:

Does your system have 'zones' ? Do you have more than one thermostat?
