17 QuestionsQ: does this include 124904 well adapter or is this not needed?

Verified Reply- Supplyhouse.com TeamThat well adapter has since been obsolete with no direct replacement. It is no longer needed for this relay.
Q: what is the purpose of the high limit stop if the dial is set to the correct temperature required
Asked by weekend warrior 8 years ago
Add your answer
Verified Reply- Supplyhouse.com TeamThe combination high limit and intermediate switching relay works with a low voltage (24V) thermostat to control burner and circulator circuits. A call for heat by the thermostat starts both the burner and the circulator. When boiler-water temperature exceeds the high-limit settings, the burner circuit is broken; the circulator continues to operate during the thermostat call for heat.

Verified Reply- Supplyhouse Staffshould be fine
Q: My furnace has a L8148A 1017 which has a 8 degree differential. This means the furnace starts back up after the water cools just 8 degrees. This seems like a big waste of hot water that could be heater my water tank, why not have a larger differential like 15 degrees ? Water only gets heated to 120 * I realize the higher the furnace temp water is the quicker the water tank will recover but what if I don't need a quick recover. I also realise that the heating of the house may suffer alittle with a larger differential but thats OK also. Is ther another Aquastat relay that mounts horizontal that has a little larger derrerential temp. ? The L8148A 1017 has a non adj. differebtial temp. What I'm trying to do is burn less oil while heating up the water tank during the summer months when heating the house is not needed.

Most of the ones I have seen have two dials in side were You can set the temp differential and that is usually 20 Degree differential and you can change them in summer When you don't need heat summer can be 120 140 or so And winter 150 170 a little higher for big house if you don't Want to wait. Not higher than 190 Sent from my iPhone

Q: I have a L8148A and would like to replace it,but I would like it to be on a cold start, I have a 6 zone controller that 30 volts come into the leads that says thermostat,above the transformer. right now the boiler comes on for temp and when one of the zone valves turn on, any ideas
Asked by Gary 14 years ago
Add your answer
Verified Reply- PexSupply StaffHoneywell does not have a lot of models that can be set for cold start. You can use the L7224U and in the installer setup turn the low limit to "Off" for a cold start application. The parameters for low voltage is 20Vac to 30Vac. A surge in voltage can cause a problem if the voltage is running as high as 30Vac and you go over the recommended voltage, so you should check to make sure this is a good fit. ,
Q: I need to replace my L8148A aquastat, do I have to drain my boiler system to replace this control, or do I simple remove this and connect the wires properly
Asked by retired contractor 14 years ago

Boiler does not have to be drained, temperature probe fits into a "well" that is surrounded by water but isolates the probe from the water.
You do not have to drain your boiler or system to replace the aquastat. Shut your boiler down electrically and when it's cool enough to work on, remove the old aquastat and replace it with the new one. The temperature probe may be difficult to remove because it's in the well and has done lot's of expanding / contracting over the vears. Once you get it out carefully reinstall the new one and use the anto-sieze compound that came with the new aquastat. Take your time, it doesn't take a long time.
Bulb is inserted into a thermal well. No need to drain the boiler.
there is no need to drain the system. the tempeture sensor is inserted in the well, which is essentially a closed end pipe that extends into the boiler cavity. the important things are (1) to use enough heat conducting compound (it comes with the aquastat) when you inserrt the bulb in the well (2) to be careful not to kink the small tube of the tempeture sensor and (3) keep track of which wire goes where. there are high (line) voltage connections and low voltage (thermostat and zone valve) connections. mix them up and you'll fry your $150 toy.
My boiler had a thermal well so the boiler did not have to be drained. There was a set screw that held the aquastat in place. The new unit had a thermal grease that you applied to the bulb, slid the bulb into the thermal well and installed the set screw. I think there were well written instruction with the new aquastat.
The boiler has a plumbing cavity into which the temperature sensor (copper probe shown in the photo) of the Aquatstat is inserted using the thermally conductive compound supplied with it. You must disable power to the system, but you do not need to drain the boiler before removing and replacing the Aquastat. Dave
No, you do not have to drain the boiler. Just unscrew the connection and install in reverse.
If your boiler has a thermowell installed that your thermocouple is inserted into currently you won't need let water out of your boiler.
All depends on the boiler. Mine is a Weil McClaine with the temp. thermocouple in a well. You should receive thermally conductive paste with your aquastat to efficiently transfer heat from the well to the TE. I believe most, but not all boilers have their temp elements mounted in a well. Hope this helps...
You do not have to drain the boiler. Just shut the power and remove and replace per the instructions.
Q: can i replace L8148j with L8148a model
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffMaybe, depending on what you're using it for. L8148A1017 is a high limit aquastat that can only be mounted horizontally. L8148J1009 is an aquastat relay that can be mounted either horizontally or vertically.
