Yankok Mechanical Thermostat Air Conditioner Fan Coil Unit Controller Manual Switch T6373B1130

Reliable Line-Voltage Control - Designed for simple heating or heating/cooling systems that require a direct line-voltage connection (120V, 208V, or 240V), commonly used with electric baseboard heaters, fan coil units, and convectors.; Dual System Capability - Can be configured to control a single heating system (2-wire) or both a heating and a cooling system (4-wire), offering flexibility for different applications without needing a separate transformer.; Simple, User-Friendly Interface - Features an intuitive manual dial for temperature selection and a clear, easy-to-read temperature scale. A built-in system switch allows users to easily turn the unit OFF, set it to HEAT, or COOL (on 4-wire models).

; Built-In Precision and Safety - Includes a mercury-free, bi-metal snap-action switch for accurate temperature control and a "built-in anticipation" feature that minimizes temperature swings for improved comfort. It also has a safety limit stop to prevent excessively high heat settings.; Durable and Easy-to-Install Design - Constructed with a sturdy, heat-resistant cover and a universal mounting plate that fits standard electrical boxes, making it a direct replacement for many older line-voltage thermostats.
