Electronic HVAC Temperature Control
The Ranco ETC-141000-000 is a single-stage digital thermostat built for heating or cooling equipment in commercial and industrial environments. Its SPDT contact form lets it switch one load between open and closed on temperature rise. The gray enclosure carries a NEMA 4 and IP67 rating for dust and water ingress protection. It suits installers who need a compact, rugged controller for a single refrigeration or HVAC circuit.
Operating Range and Electrical Limits
The controller operates from -30 °F to 220 °F with an adjustable differential of 1 °F to 30 °F. It accepts 120 V AC, 208 V AC, or 240 V AC input voltage without variable output. The fixed voltage options and single-stage action mean it cannot stage multiple compressors or modulate capacity. Buyers who need multi-stage sequencing or analogue output must select a different device.
Installation Notes
The unit mounts in a standard enclosure and measures 7 7/8 inches overall height. Wiring follows the SPDT terminal layout for either heating or cooling mode, selected during setup. Common issues include reversing the load wires so the contact opens instead of closes on rise, and exceeding the 30 °F maximum differential when a tighter deadband is required. Verify the supply voltage matches one of the three rated inputs before powering the control.

Questions about this item
Should I pick the SPDT or another contact form for my heating and cooling setup?
This control uses a single SPDT contact, so it can switch either a heating or a cooling circuit but not both at the same time.
What does the -30 °F to 220 °F range mean when the unit is installed in a real HVAC system?
The controller can maintain set-points anywhere between -30 °F and 220 °F with a differential adjustable from 1 °F to 30 °F, covering most residential and light-commercial heating and cooling loads.
The IP67 rating is highlighted — what does that cap in practice for mounting location?
IP67 means the enclosure is dust-tight and survives temporary immersion, so it can be mounted in wet or wash-down areas without extra protection.
