T26A-15C Johnson Controls Thermostat

Overview

The Johnson Controls T26A-15C is a line-voltage mechanical wall thermostat designed for energy conservation in heating-only applications. It features a single-pole, single-throw (SPST) snap-acting switch enclosed in a dust-protected housing, operating without the need for heat anticipators. The device utilizes a liquid-filled sensing element that offers excellent sensitivity to surrounding air temperature changes, paired with a diaphragm and lever mechanism to provide close temperature control for residential, commercial, or industrial electric heating systems.

Features

• Liquid-filled sensing element provides high sensitivity to temperature variations.
• Close differential operation without requiring heat or cold anticipators.
• Enclosed Pennswitch snap-acting contacts offer reliable dust protection.
• Energy conservation design with a restricted maximum temperature setting of 65°F.
• High-impact plastic thermoplastic enclosure in an attractive beige finish.
• Dual-mounting versatility, supplied with a vertical faceplate and includes a horizontal faceplate option.
• Adjusting knob and easy-to-read dial allow quick temperature selection.
