Same as Honeywell
Used to control woodstove, original Honeywell lost its calibration and wouldn't shut off unless it was set 50 degrees cooler.
They should make it easier to connect stranded wire.

Q: I am a building contractor and I installed a Super Store Ultra water storage tank as part of a hydronic water and space heating system. I used a Honeywell L4006A2007 aquastat to regulate the water temperature in the Super Stor Ultra tank. Recently the water temperature has not been accurate and the boiler is not being activated when the tank drops below 120 degrees. This is the third aquastat that I have installed in this system since 2009. Is this normal? What is the typical longevity of these units? My owner uses the residence less than half of the year and may be doing something to affect this condition. When he leaves, I believe he adjusts the aquastat to keep the boiler from coming on too often. I would be installing the 4th aquastat in 6 years of operation.

Verified Reply- Supplyhouse StaffNo it is not, we wouldn't know how long these units last. You can try calling Honeywell directly for more information.

Q: Can the bulb be directly immersed in ¾ cooper tube hot water line? Does the enclosure need a separate support or can the bulb support it?
Asked by Adolf 11 years ago
Add your answer
Verified Reply- Supplyhouse StaffThe bulb needs to be installed in a well, the enclosure does need to be supported separately, it does have mounting holes in the back to be direct mounted.

Q: wanting to install a low-temp shut off for my wood fired boiler. meaning the blower and damper would shut off when the wood is burnt and the water temp gets below a certain temp, and when the temp is above the low temp cutout, the circuit is closed and keeps power to the effected systems. will this unit work for me?

Q: how is the Aquastat wired to circulating pump?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffYou will need to wire the aquastat to a switching relay.
Was this review helpful to you?
- Ken
you need a relay to handle the power load of the circulator
Was this review helpful to you?
- Denton
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.
Asked by Bill 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe L4006A2007 aquastat has an adjustable differential between 5°F and 30°F with an operating temperature range of 100°F to 240°F. 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.

Q: I am in need of a new aquastat.(due to short cycling) My current aquastat is obsolete, it is a L4031 D ( I can find no info on this aquastat. The boiler is a gas,tankless boiler.( a remote bulb will be neccesary.( 10") I would like to find a all in one unit, that is a high/diff/circulator. Thank you
Asked by bob 15 years ago

Q: how do you adjust the temperature differential?
Asked by 16 years ago
Add your answer
Verified Reply- PexSupply StaffSet 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.
