Product Q&A
3 QuestionsQ: Can this be used in place of the smart control on a wh7, if not do they make one with a manual dial and face plate
Asked by Bob 8 years ago

Verified Reply- SupplyHouse StaffThe WH-7 lists the SmartControl (SKU: 940R101) and this dial aquastat as two separate accessories, but both are compatible with that model.
Q: I believe after 19 years of perfect service, it now seems to me I have to switch out my thermostat for my Amtrol WH 7L 41 Gal. The tag hanging from the original says "replace thermostat without draining tank." Is it as simple as that? Looks simple enough....should I have any concerns or reservations before I order and do it myself? thanks, Larry

Larry, I had this part fail on my water tank, which would cause it to always indicate that the water needed to be heated. When I replaced it, it did not require draining the tank or anything special. There is an access panel on the bottom that I removed to gain access to where the thermometer was inserted to the water tank (center bottom). You will have to unscrew the retaining bolt (you can see the new one on the catheter in the picture next to the knob unit) and slide out the old bulb. When I put in the new one, I just slid it in all the way then tightened the nut down so it was snug. I wasn't sure if tightening too hard would crush the catheter or not, so I figured I would just leave it snug. That was it, probably 5 minutes from start to end. I hope this helps. -Nate
you dont drain the tank simple as unthreading the old sending rod and reattaching the wires took me no tinme at all
Larry it's that simple -carefully insert all the way and backout a little (1/4") and snug the nut to hold in place. Best if you can bend the bulb sensing line about 1" from the bulb so the bulb makes contact inside the tube on the hot water tank. (careful not to kink). I also had to change the relay and the gasket on bottom of tank which required tank draining for the gasket. (gasket was leaking). Relay has been updated and is an excellent replacement. A screw holds the knob on the thermostat.
Q: Does the 2704-093 Aquastat/thermostat control the ingnition of the oil burner as well as the circulator? My oil burner has been locking out more often since there is less call for heating. The water heater is connected to the boiler as a seperate zone.

Verified Reply- PexSupply StaffIt would still be looked at as another zone, as any indirect water heater would be.
