Emerson White-Rodgers demonstrates New Integrated Furnace Controls Universal Replacement

March 29, 2023

At the 4th Annual HVACR Training Symposium, Bert checks in with Jim Fultz from Emerson White-Rodgers, who demonstrates the capabilities of the new 50M56X-843 Integrated Furnace Controls Universal Replacement. The two also say a few words about the Emerson White-Rodgers Universal Premium Flame Sensor and All-Spark ignition module.

The new board essentially combined the best qualities of two previously released boards, the 50M56U-843 (single-stage HSI integrated furnace control for PSC motors) and the 50X57-843 (single-stage HSI integrated furnace control for X13 motors). It can replace furnace controls for systems with PSC or X13 motors (550+ cross-references) without all the harnesses; the control can configure everything that is plugged into it without you worrying about harnesses or DIP switches.

The 50M56X-843 also allows thermostat wires to plug into it directly and has test pins for flame sensing. It also has an LED display that shows exactly what is happening; it can alternate between showing the operating mode and the operating current, so you don’t need to use a meter to test your flame sensor. The LED display will also show the error code when the board detects a problem.

These boards work well with Emerson White-Rodgers Universal Premium Flame Sensor, which comes with a cross-reference chart you can use to bend or cut it to replace over 1000 OEM parts.

Like the Emerson White-Rodgers All-Spark, the 50M56X-843 also uses near-field communication (NFC) technology for quick and easy configuration through the WR Connect app on your smartphone. You don’t need an internet connection, cellular data, or power to the control to configure it with your smartphone. The app can also let you adjust the cool, heat, or fan settings on/off and offers a diagnostics tab.

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this short Q&A podcast episode, Bryan answers a listener-submitted question and gives some of his tips for moving to HVAC sales from field technician/installer roles. The world of sales has a different pay structure, which makes it an appealing option to many technicians.

Salespeople need to be able to have money conversations with confidence and not be afraid to talk about pricing. You can practice these conversations with friends or fellow technicians, including answering questions and responding to objections.

Sales confidence is another key to success in sales. Many successful sales techs go into sales with the assumption that the client wants to work with them and aren’t timid because they’re confident they’ll make the sale. Great salespeople also seek out feedback to learn and grow from.

Many great salespeople in the HVAC industry also benefit from learning about load calculations, equipment selection, and duct design, particularly via the ACCA manuals and software like Wrightsoft and Kwik Model 3D. The HVAC Grapevine, NCI, and TEC all have great educational resources about building science. Deploying test instruments, including blower doors, duct blasters, and thermal imaging cameras, also gives you vital information about the structure and shows clients that you’re going above and beyond for their comfort; you’re delivering quality and doing so with integrity.

Communication skills are a crucial part of sales, and the best thing you can do to start honing your communication skills is to ask good questions and listen for valuable answers. Empathy is also important in sales, and it’s most effective when you can understand your client’s priorities.
