King Electric Window Watcher Thermostat with Sensors

The King Electric Window Watcher Programmable Thermostat with Sensors is an energy-saving thermostat designed to automatically reduce heating inefficiency in dorms, apartments, hotels, vacation rentals, and multi-family properties. 

This precision-smart thermostat monitors room activity and responds to open windows or prolonged inactivity, setting temperatures back to energy-efficient levels without any user intervention. It features motion sensors, window contact integration, dual setback temperatures, and easy push-button controls, making it one of the most effective energy-saving thermostats available for 120V or 208/240V systems.

Whether you’re a property manager looking to reduce utility expenses or a homeowner wanting a smarter and more responsive thermostat for home comfort, the Window Watcher is a practical solution. 

Key Features and Benefits of the King Electric Window Watcher Programmable Thermostat

• Automatic Setback for Energy Savings: The window sensor detects open windows, automatically reducing heat to a fixed low of 40 degrees F when the window is left open. The optional motion sensor detects inactivity and sets temperatures to a fixed low of 60 degrees F when the room is left unoccupied to prevent energy waste.
• Precision Temperature Control: Electronic sensing maintains temperatures within ±0.9 degrees F of your preferred temperature, optimizing comfort while reducing unnecessary energy usage.
• Tamper-Resistant Presets: Limits maximum room temperature to 74 degrees F to ensure property managers and homeowners control the energy usage even when guests are present.               
• Automatic Restart: In the case of a power failure, the thermostat will restart with the previous occupant’s setpoints once power returns.
• Flexible Integration: Works with optional magnetic window contacts, motion sensors, and hotel-style key cards to trigger temperature setbacks automatically.
• Simple Operation: Easy-to-use up and down temperature buttons and a large LCD screen make it accessible for everyday users without needing Wi-Fi or app controls.
• Durable & Versatile: Rated for up to 3840 watts at 240V and compatible with fan-forced, baseboard, and radiant heaters. It mounts to standard wall boxes and fits 120V (WRP120-B-KIT) or 208/240V (WRP230-B-KIT) systems.

Multiple Models Available

Both kits provide the same thermostat features with different voltage compatibility:

• WRP120-B-KIT: It is designed for 120V heating systems and includes a thermostat and wiring for single-pole applications.
• WRP230-B-KIT: Designed for 208/240V systems and suitable for baseboards or wall heaters requiring higher voltage capacity up to 3840 watts.

Note: Select the model that matches your building’s line voltage.

Smart Automation Without Complex Wiring

Unlike traditional AC thermostats, the Window Watcher is a stand-alone line voltage thermostat that doesn’t require Wi-Fi or mobile apps. Instead, it uses low-voltage signal inputs—like window contacts or motion sensors—to trigger real-time changes in temperature.

For property managers, you get the benefits of smart heating control without installing building-wide automation systems. It’s an efficient way to reduce energy waste in spaces where heating is left running without consistent intervention.
