Does anyone know if there are 50 degree range aquastats ?

[Pat53]

I know 30 degree range aquastats are the norm, does anyone know if they make 40-50 degree range aquastats?

thanks

Do you mean the differential adjustment? Honeywell T775 have a 1-35.
HeatTimer had a 0-100 differential on their Digistat controls, nice for buffer tank controls. I'm not sure if they still offer that model?

Greetings,

Check out the Azel DST777 (available with single (S) or dual (D) outputs) set point control.

This unit has a -40F to 240F temp range and a programmable 1-100F differential adjustment.

In addition, it comes with a 10K Ohm sensor that can be extended up to 500 ft. using T stat wire.

Their website is www.azeltec.com

They also have some really nice dual temperature (with memory reset) DP60 temperatute gages that utilize the same sensors.

If you interested in these please email me at [email protected] and I can email you literature on them.

I am located in East Jordan, MI.

thanks guys, what I want the high range aquastat is for my boiler draft. I'll be using storage this season, and I would like to have my draft open when water temp drops to 145F-150F and closes at 190-195F.
