Comments about Electronic Temperature Controller (24/120/208/240 Volts AC):

This is a great unit. It has endless applications and is so easy to use and program. I used it as an Aquastat to talk to a TACO SW-501 (switching relay) which then calls up a circ. pump and a heat pump in order to control the temp. in an 80 gallon buffering tank in a heat-pump-driven hydronic heating system. Having a digital read out is so nice and it operates on 24 - 240 vac.

Comments about Electronic Temperature Controller (24/120/208/240 Volts AC):

I have changed old one(I don't remember maker).
That can't cut down the m/c, so my merchandise are freezing.
But, I'm wonderful with this one.
It's very easy install & controll.


Excellant for ceiling hot air distribu.

Comments about Electronic Temperature Controller (24/120/208/240 Volts AC):

I was told by several people that I could not set a specific temp. to turn on my fan and also a specific temp. at which to cut the fan off,but with this unit you can set the temp. at which you want the fan to start such as 75degrees and then set a differential of 3 degrees and the fan will turn on at 75 and then turn off at 72. So for all practical purposes you have established 2 specific set points for the fan. Works great!

  • Electronic Temperature Controller (24/120/208/240 Volts AC)


    i have this aquastat on a boiler i just bought. its hooked up to cut the stoker fan on when needed. can i use this aquastat to cut on my circulator pump when the thermostat in the house calls for heat??

      Yes, you would be able to use this aquastat to control your circulator pump. You would have to use an additional controller though. You would not be able to link the fan and the pump into this one controlling unit. The wiring diagrams can be viewed on page two of the product data sheet below: http://s3.pexsupply.com/manuals/1257434354611/19051_PROD_FILE.pdf

    • A:

      the best and cheapest way to accomplish this is to use a pilot relay matched with the output voltage of your thermostat usually 24V. should be under $20.
