STC-3008 Dual-Relay Temperature Controller

Control two temperature-based switching channels from one panel. The STC-3008 combines digital readings, separate start/stop settings and two relay outputs for a correctly designed heating or cooling arrangement.

✅ Set switching points for each channel - Separate start and stop settings define the response of the two control sections.

✅ Read the temperatures at the controller - Digital displays give the connected probe readings a local viewing point.

✅ Choose the supply version for the installation - DC 12 V, DC 24 V and AC 110-220 V options provide distinct power variants.

Define the Temperature Response Before Connecting the Load

A control job needs both a measured temperature and a rule for what happens next. The controller uses the start/stop relationship to define heating or cooling behaviour, so set each channel around the actual application.

Choose the correct supply version and confirm the relay's rating for the specific load type. Have electrical integration carried out appropriately and use any independent limits required by the process. This is a temperature controller; it is not described here as a humidity-measuring instrument.
