Info & Guides

Description

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.

Sylvane's Expert Take

The King Electric Window Watcher Programmable Thermostat is ideal for anyone seeking low-maintenance energy savings and better control over room heating. It’s not just another King Electric thermostat—it’s a purpose-built tool for reducing costs in spaces where heat is frequently and unnecessarily left on.

With its precision temperature accuracy, dual setback timers, and optional sensor integration, this thermostat offers a smart, automatic approach to energy conservation. Whether you're managing rentals, overseeing a campus facility, or simply want an energy-saving thermostat that takes the guesswork out of efficiency, the Window Watcher earns its place in your space.
