Sounds about right.

Do you have the "PRE-PURGE" turned on?

What do you have "ECONOMY" set at?

Is the home heating properly?

Is your system set up for multiple zones? if so, how many?


whats the pre purge?
You have manual? It's in there (page 7)... if not, download here:

48-3250 - Hydrolevel 48-3250 - Model 3250 Fuel Smart Hydrostat

should i have the pre purge on?
Sure, why wouldn't you want it?

When you say "on the dial..." do you mean the LED DISPLAY ?

My first impression is that the boiler gauge might be 'off'...

You may also have a defective temperature sensor for the control.

When in operation, does the AMBER "TARGET" LED light up?

when in operation the amber light on target is not alluminated.

update

so after the boiler was on and then the zone upstairs stopped calling for heat the boiler turned off and the "target amber light was on" the temp in the boiler guage was at 145 and the led temp was 151.

Sounds OK to me.

The "target" temperature is that which the control calculates is needed to heat the home.

A difference between 145 and 151 is nothing to be concerned with.

Turning on pre-purge should save a couple bucks.
