        Not working as hoped for.

              I taped the sensor bulb to a hot water circulating loop in an effort to control the loop pump. The bulb is not sensing the heat from the pipe accurately. I have order a "well" to install in the line (via a tee) in hopes of a more sensitive operation. The well has not arrived so I can't tell you if it will work.

                    Bought this as a fail safe high limit in a hydronic system to which I added an outdoor reset control. The first unit I received was misassembled and non-functional. After a quick and cheerful replacement by Pex Supply, the unit works as expected.

                                A great product at a great price. I was having problems with my wood furnace maintaining the proper water temp. After installing the Honeywell Aquastat, no problems. Getting a better burn life out of my wood too.

                                        Q:

                                        Can I use this control to send a dry contact signal to call on a the oil boiler when the temperature in the tank connected to my wood boiler drops below 130 deg ?

                                          I believe this item can be used as indicated in the question.
                                          I use the L4008A to control the heat source (waste oil burner) to a water tank to keep the water between a certain range (about 140 degrees to about 155 degrees). It is connected to a Beckett GeniSys 7505 controller which controls the burner and related mechanics (starter flame, air source, flame sensor, etc.). The aquastat tells the Beckett controller to fire up the burner when the water drops to the lower limit. It tells the Beckett to turn off the burner when the water reaches the upper limit.
                                          In my case, the L4008A is connected to a 120V supply voltage. It acts as a switch to provide a power signal to the Beckett controller. I don't believe the aquastat needs a supply voltage. It is simply a temperature controlled switch that can be dry or provide a power signal.

                                          The control in question can be used for your application as I understand
                                          your description. In fact, it is how I use it… when my wood boiler drops
                                          below 140 degrees (no useful heat left in the water for me), the contacts of
                                          the control closes on thermostat wire circuit and calls my oil boiler to
                                          come on. If I re-fire my wood boiler and the water temperature comes up to
                                          100 degrees, the control contacts open and my oil boiler shuts off.
