2 QuestionsQ: I need to replace my aquastat, the part # on mine is just L4006B, is the L4006B1163 compatable?

Verified Reply- Supplyhouse StaffWe would need the 4 digits after the B to confirm the correct replacement.
Q: Setting the low temp cut out at 160 with 20 degree differial means the pump will restart at 180? Or do I set it at 180 (cut in temp) and expect it to cut off at 160? No instruction sheet provided in severely aged box,..new unused but shelf and handling abuse,

You must always set the unit for the temperature at which you want the comntacts to transfer, the contacts will then stayed in the transferred position until the temperature has changed equal to the differential. (note: be sure you have the right unit. some are designed with normally open contacts and close with an increase in temperature, others are designed with normally closed contacts and open with an increase in temperature.) The unit in question here (L4006B1163), is one with normally open contacts and will close with an increase in temperature. Therefore: If set at 180 degrees with a 20 degree differential. It will transfer (close) the contacts at 180 degrees and they will remain closed until the temperature decreases to 160 degrees. Hope this helps L. Kaufman .
On a hot water boiler system with a circulating pump, the setpoint on the aquatat is considered the high limit which is when the flame cuts out and the pump cuts in. As the temperature drops according to your set differential to reach your low limit, the flame cuts in and the circulator pump cuts out. The cycle then repeats. The instruction sheet may be available on-line on the Honeywell website.
Here's the instruction sheet: http://customer.honeywell.com/techlit/pdf/60-0000s/60-0915.pdf Good luck!
Here is documentation I found online. The link is to the PDF document directly from Honeywell. Watch the part numbers. The "B" is what you have, but the documentation covers a family of controllers, not just one specific model. The way I read it is the controller will cut out at 160 and with a 20 degree differential, will cut back in at 180. L4006B makes the circuit on a temperature rise. It is used as a circulator controller, delaying circulator operation when boiler water temperature is below the control setting. http://customer.honeywell.com/techlit/pdf/60-0000s/60-0915.pdf
This switch is designed to engage at a temperature setpoint. the differential is the amount where the circuit will open up again. For example, if it is set to come on at 180 deg F with a 20 deg differential then it will stay on until the system cools down to 160 Deg F and then drop out. There are instructions for this device under Honeywell's website. My wood/coal boiler uses this device for the over-temperature circuit to turn on the heating loop I use for a dump zone. I set it at 190 deg F with a 5 deg differential. Best regards, Andy Thorpe
