Hello, thanks for writing in. No, you would need one aquastat per unit.
sure can.
No it is mounted below unit and has a strap to attach to pipe Ken Jackson
It only Six to seven inches long Sent from my iPhone
Hi This model is mounted to a pipe (3/4 inch copper) in my case and the bulb (temperature sensor ) is under the control and relay connected by a small copper tube. There was no way in this model to mount the temp sensor away from the relay housing since the mount is what makes the physical contact with the pipe and the tube is short and rather rigid.
Hi Yes the behavior you see is most likely intentional. I have one of these Aquastats on a blower using a System 2000 boiler and the system 2000 will continue to circulate the hot water after the Thermostat shuts off and until 5 minutes. So in my case it continues to blow warm air which is ideal. (On ~ 150 off ~ 125.) However if another device calls for the boiler, the hot water line will stop to my blower and the blower will run for a while because the line has not cooled. Originally my system used to blow air controlled by the thermostat only. So I got cold air initially (for a short period until the boiler warmed up.) And then it shut off waiting for another call for heat. It left the boiler warm too. I'm guessing yours was originally way too. So there is most likely a relay that could turn your blower on only when _both_ the temperature and the thermostat are on, if the cool air bothers you . Disclaimer get an electrician to check it out. The other possibility is your boiler does have the ability to circulate hot water for a while after the thermostat turns off. Check your boiler manual. Cheers
The item is an aquastat and it measures the temperature of the hot water flowing through pipes feeding the Modine. It turns the Modine fan on when the water temperature drops and off when the water temperature reaches the desired setting. It does not measure the room temperature.
This is normal.
I used the aquastat on my wood boiler (heat and domestic hot water) to activate a dump zone when the system reached a certain temp. (used as a normally open switch, when setpoint reached going low temp - to hi temp the circuit was closed)
If you are controlling 2 items that you want to turn on and off at the same time one aquastat will work. If you want to turn them on and off at different times you will need more then one.
Should work fine. I use it to control flow on a hot water coil in my coal furnace. The aquastat turns the pump on when the water in the coil is around 150 and shuts off around 135. That way I'm not ciculating cold water into the top of my hot water tank.
This aquastat does not have an extended capillary, but it does include a bracket for strap-on mounting.
The capillary sensor itself is about 3 inches long, as shown in the photo. The tube between the sensor and the unit is only long enough to reach the sensor bulb which is within the back of the unit. This unit is designed only to strap directly on to the pipe and the directions indicate it requires one inch or greater diameter. I am using it on a half inch pipe and need to modify it by adding some spacers as the bracket is wider than a half inch. When the unit is installed it is on the pipe and the capillary sensor is held to the pipe by the unit itself. The sensor is not visible or accessible when the unit is clamped onto the pipe. If you need a unit with a remotely mounted sensor that is a different model, also available at PEX.
This aquastat meets all your specifications. It works as a circulator control, features a bracket for strap-on mounting, has a temperature range of 65°F to 200°F, and an adjustable differential between 5°F and 30°F.
This unit would not wire to a switching relay. Please refer to Page 14, Figure 22 of the manual below. http://s3.pexsupply.com/manuals/1303919167040/54523_PROD_FILE.pdf
