Dwyer Instruments TSW Series User Manual

Dwyer ETC Controller Quick Start:
The dwyer ETC controller is a simple dual stage controller. This means that you can control
heating and cooling functions with this unit. It needs a few minutes of setting up by you before
you can brew, but you’ll be up and at it in around 5 minutes. There are many ways to program
this controller, as it can provide temperature alerts, etc. Because we want you to begin to use it
as soon as possible, we’re just covering the functions that we feel are relevant.
Always plug your Dwyer Controller into a GFCI protected circuit.
The dwyer has 2 outputs, one for cooling and one for heating.
Set up:
On the front face you can see the set button.
•
Long press this for at least 8 seconds The access code value 0 will show on the display.
•
Press set button again and you will keep the setting at 0, SP1 will show on the display.
•
Press the up arrow repeatedly until r1 shows on the display. This is the Differential for SP1
which is your heating element. It can be lowered for more sensitivity of the heating element
and therefore your mash cycle. Press set to change the value from 1 degree. It can be fine
tuned all the way to 0.1 degrees. Press set again to exit.
