The video by Tech dven focuses on installing the Honeywell RTH9585 WF smart Wi-Fi thermostat in a warehouse lacking a C wire. Tech provides a step-by-step guide, emphasizing essential tools and safety precautions, especially ensuring the power is off before beginning. He explains how to use a 24V AC transformer to compensate for the absence of a C wire and details wiring connections, including the significance of terminal labels. Tech also covers handling older wiring systems, the difficulty of dealing with stiff cables, and the importance of documenting the existing setup. Post-installation, he reviews the thermostat's functionality, ensuring it powers on, and the heater operates as expected. The video concludes with tips on using the thermostat, including mobile control, and invites viewer interaction through likes, subscriptions, and comments.

In this part of the video, Tech from Tech dven introduces the Honeywell smart call thermostat model RTH9585 WF, which is both smart and Wi-Fi capable. He plans to replace an old Honeywell thermostat in his warehouse that likely has only two wires due to its age and lack of a C wire, which the new thermostat requires. Tech explains the process of checking the existing thermostat wiring, noting that older models with only two wires can still work using a version with batteries. He emphasizes the importance of verifying the type of thermostat and the voltage requirements before beginning the installation. Tech also mentions using a 24V AC transformer to power the new thermostat since the existing setup lacks a C wire.

In this segment, the speaker discusses the tools and materials needed for installing a smart thermostat. They mention that links to the products are available in the video description and purchasing through these links provides a small commission to support the channel. Key items needed include a screwdriver, pliers, clippers, a knife, a 24-volt AC transformer (especially if no C wire is present), a smart Wi-Fi thermostat, and a touchless voltmeter for safety. The speaker emphasizes the importance of ensuring the power is off to avoid hazards. They begin preparing the thermostat by opening the box, examining the mounting plate and screws, and discussing the wiring connections, particularly focusing on homes without a C wire. The segment ends with unwinding the cable for proper setup.

In this part of the video, the speaker discusses connecting a new thermostat. They mention needing a short wire since their power outlet is close to the old thermostat, but note that the 24-volt AC power transformers typically come with long cables for flexibility. The video highlights the importance of checking the terminal labels (e.g., C, K, RCR) and disconnecting the jumper if unnecessary, specifically when using an external power supply. The speaker details connecting the wires: the red wire (R) and white wire (W) to their respective terminals, and the transformer power to terminals C and RC, emphasizing that the polarity doesn’t matter for AC cables. The speaker also suggests trimming terminal ends if they are too long and struggles a bit to snap the cables into place while explaining the process.

In this part of the video, the speaker discusses handling and installing stiffer, solid cables, noting the difficulty in pushing them due to self-locking pins. Key actions include threading the cable through the bracket, securing it by pushing on a tab, and connecting the AC transformer to the RC. Moving to the thermostat, the speaker demonstrates turning off the heat and then using the breaker to ensure safety by cutting the power. They test the voltage with a tester to confirm power is off before removing the thermostat cover. The speaker advises taking a picture of the wiring for reference before unscrewing it, emphasizing the variability in wiring standards, particularly with older systems. They mention retaining the old thermostat for potential future use.

In this part of the video, the speaker addresses working with an old wiring system. They mention having plenty of cable to use and proceed to unscrew and disconnect existing wires, noting the color coding (red to red and white to white). They decide to keep an existing plate in place for future use and begin threading new cables through a hole, which proves challenging. The speaker mentions the solid nature of the wires makes it easier to push them inside the terminal. After ensuring the connections are properly locked in place, they double-check their wiring against a prepared diagram. The connections include the heater wires going to terminals R and W on the thermostat and the transformer connecting to RC and C.

In this part of the video, the speaker discusses the importance of removing a jumper to avoid duplicating the AC current, which could potentially cause damage. They proceed to screw in a component and adjust it to ensure it is level, emphasizing functionality over appearance as it is for a warehouse. After plugging in the thermostat and flipping the breaker, the speaker verifies the power connection and runs through the setup to turn on the heater. They set the desired temperature and confirm that the heater turns on with a slight delay, indicating successful gas ignition.
