These temperature controllers really work. You can't beat the price. The displays are bright and easy to read. Quick to install , wire, and program. Great that they have different footprints for all my needs.
Documentation is pretty complete and good. Configuration has a steep learning curve. Analog scaling a 0-5 VDC range requires setting the control to "-3795" (arbitrary units: -3795 scales to ~5.000 vdc) "-3795" includes a "-2000" rollover. So after you start from 9999 (?), the setting shows -1795 instead of -3795. Changing parameter values/settings is awkward because buttons are tiny and stiff (hidden behind membrane graphics). They require a lot of force to press and hold down, and have unexpected number-change-speed rate changes. (Overshoots are easy.) That said, hardware (analog i/o and RS485 comms) is a real value for this price. I recommend it when the learning curve (first unit) makes the performance worth it.
I have used several different sizes of the solo temp controllers and they all work perfectly Very easy to install and setup Never had to reprogram or readjust I use these controllers on product reactors for heating and cooling In addition I use them for monitors on critical equipment such as deep freezers Hot boxes boilers etc1 person found this review helpful.
We incorporated this controller into our tortilla machine and immediately achieved very impressive temperature control using an RTD sensor. Previously we had an 18% temperature variance - now it is 2%.
Bought several units and they all worked perfectly the first time and are still working. That was over 6 months ago.2 of 2 people found this review helpful.
