The short version: Robertshaw is a long-established name in HVAC controls, sold almost entirely through distributors rather than consumer retail. We could not confirm “RS10K” or “RS8620” as exact current model numbers against Robertshaw’s own catalog — the closest documented Wi-Fi model we found in Robertshaw’s Pro Series is the RS10420T, a touchscreen, app-connected thermostat with Alexa support. If you’re shopping this model, confirm the exact SKU with the seller or Robertshaw directly, since this brand’s naming across programmable, non-programmable, and Wi-Fi lines is easy to mix up.

Worth knowing before you buy: Robertshaw filed for Chapter 11 bankruptcy in 2023 and completed its sale and restructuring in 2024, emerging under new ownership. That doesn’t necessarily affect product quality, but it’s the kind of context worth having about a company before you buy a connected device that depends on ongoing app and cloud support.

Who It’s For

Robertshaw’s thermostats are sold mainly to HVAC contractors and through distributor sites, with limited presence on Amazon. Its Wi-Fi Pro Series models support multi-stage conventional and heat pump systems (up to 4 heat/2 cool on some models) and include app and Alexa control.

This is a fit for buyers replacing an existing Robertshaw thermostat or working with a contractor who specifies the brand. It’s not a fit if you want a well-documented consumer track record before buying — independent owner reviews for this brand are essentially nonexistent in general search and retail listings.

Setup & Compatibility

Robertshaw’s Pro Series Wi-Fi thermostats use a large backlit touchscreen and a universal sub-base designed for straightforward wiring, with support for multi-stage heat/cool configurations and features like adjustable compressor delay and temperature calibration common to the professional-controls end of the market. As with any lower-information purchase, confirm the exact model’s heat/cool staging and C-wire requirement against your system before buying.

App & Ecosystem

Robertshaw’s Wi-Fi models connect through a manufacturer app for remote scheduling and support Amazon Alexa on select SKUs. We found no independent reviews assessing the app’s reliability or update cadence, and no forum or retail-review discussion of real-world ownership experience. Given the brand’s recent bankruptcy and ownership change, it’s reasonable to ask a contractor or Robertshaw directly about the current state of app and cloud support before relying on it long-term.

The Recommendation

Consider a Robertshaw Wi-Fi thermostat only if you’re working with a contractor who specifies the brand or you’re replacing an existing Robertshaw unit — confirm the exact model number and current app support before ordering.

For a Wi-Fi thermostat with a longer, better-documented reliability track record, Honeywell’s T4 Pro or Emerson’s Sensi are safer defaults at a similar price.

Frequently Asked Questions

Is Robertshaw still in business?
Yes. Robertshaw filed for Chapter 11 bankruptcy in 2023 and completed a sale and restructuring in 2024, emerging under new ownership (backed by One Rock Capital Partners). It continues to sell HVAC controls, including thermostats, through its distributor network.

Does the Robertshaw RS10K/RS8620 need a C-wire?
Likely yes for continuous Wi-Fi operation, though this varies by exact model. Confirm with the specific product’s installation guide before buying.

Why can’t I find owner reviews for Robertshaw thermostats?
The brand sells almost entirely through HVAC distributors and contractors rather than high-volume consumer retail, so it doesn’t accumulate the review base that Nest, ecobee, or Honeywell do. If you’re buying through a contractor, ask them directly about their experience with the brand.
