Features

  • Totally enclosed Micro Switch+ snap-acting switches operate on temperature rise to setpoint.
  • Visible control point scale and external adjustment screw permit easy setting.
  • Horizontal or vertical insertion of the sensing element.
  • Direct or well immersion of the sensing element.
  • Models available for strap-on mounting. Remote bulb model may be used to sense air temperature in ducts and in outside air sensing applications.
  • Select models have wells.

              I replaced the original aquastat on my outside woodburning furnace with this unit because I needed one which I could set to a higher temperature. This one served the purpose fine. Everything changed out perfectly.

                    This keeps my stove from over heating. I have a motor operated air intake on the stove. When power is cut, the unit closes the intake... With this aquastat installed inline with the motor's power cord, I can set the temp for cutting the power, as well as the differential... I set mine to 150 degrees with a 10 degree differential, so when the power is cut, it doesn't turn on again until it drops to 140 degrees. Now I feel like I am in complete control!

                                                      You will need to wire the aquastat to a switching relay.

                                                      This switch doesn't need a relay unless your pump is over 8 amp. 120 volts... Just hook it in series before the pump, and power will be supplied until it hits the set point.

                                                    Q:

                                                    I currently have a 40gal. indirect fired hot water tank controlled by an older Honeywell L4080B-1295 aquastat, setpoint at 140 degF. with a 15 deg. fixed differential. I would like to be able to reduce the differential to between 5 and 10 deg. to allow the boiler to cycle sooner and regulate the water temp. at approx. between 135-145F. Would the L4006A2007 be the right solution? I'm confused about what "High or Limit" means exactly. My existing aquastat is only High limit. Thanks.

The "high or low limit" means that the aquastat can activate the device connected to it at either the high or the low set point.

                                                      A:

                                                      Set the differential to correspond with the boiler manufacturer recommendations. To adjust the temperature differential, rotate the wheel on the back of the snap switch until the desired reading is aligned with the V notch in the frame. The wheel provides an adjustment from 5 degrees F to 30 degrees F. Replace the cover on the Aquastat Controller. Adjust the control point to correspond with the boiler manufacturer recommendations. To adjust, inset a screwdriver in the slotted screw type head located beneath the window in the cover. Turn the scale to the desired control point.
