A new Raychem SENZ thermostat

"When designing a new product, there are three stages: design, development and launch. The first stage is by far the most important one. The clearer you define your product’s design, the easier it is to translate it to others in the following stages. Human Interface Group’s approach helped us to define a design that met our clients’ needs. And by doing so, it saved us time and money in the development stage."

To keep its pole position in the market, Pentair Thermal Management knew they needed to start working on a new high quality thermostat that was easy to use, good-looking, and in keeping with the latest screen technology.

What seemed like an easy job, quickly turned out to be a lot more challenging:

  • Could we use touch and swiping gestures?
    The new Raychem SENZ thermostat needed to fit within a switchgear frame, which resulted in a 2-inch screen size. This meant that we needed to think carefully on how controls on the screen could be manipulated.
  • Would we be able to come up with one design, or would we need different ones?
    People often choose a thermostat that fits within the concept of their home. The challenge was to come up with a thermostat that could fit into different interior styles.
  • Could we design one thermostat to fit all markets?
    The thermostat would be marketed in different countries all over the world. User needs and design preferences vary in different countries.

 

The new Raychem SENZ thermostat

The thermostat was marketed in two versions, a standard version and a Wi-Fi version. This way, the thermostat meeted the growing demands of the home automation and Internet of things market. Three color versions (anthracite, silver and white) were developed to fit customers’ interiors.

Pentair Thermal Management also developed an app to accompany the Wi-Fi version. The thermostat’s interface could easily be translated to the app, which results in a consistent look-and-feel and very recognizable interaction patterns for the user on both devices.

 

Designing the interface

We designed three different mock-ups. It allowed us to make the different ways of manipulating the screen more tangible. It provided us with the necessary tools to validate the design concept with internal stakeholders and with end users.

1: Interaction solely through hardware buttons

Hardware buttons - Home screen   Hardware buttons - Menu screen   Hardware buttons - Edit screen

2: Manipulating the controls via touch gestures but no swiping

Swipe interaction - Home screen   Swipe interaction - Menu screen   Swipe interaction - Edit screen

3: Manipulating the controls on the screen via touch and swiping gestures

Touch interaction - Home screen   Touch interaction - Menu screen   Touch interaction - Edit screen

 

Testing

Since it was impossible within the budget and time constraints to test the three design concepts in every country, we selected two very important markets, Stockholm and Paris, in which the heating system is used very differently. The clear winner of the user tests was the mock-up version with touch and swiping gestures.

 

Designing the visual style

In addition to choosing the interaction with the thermostat, we also needed to define the visual style of the user interface. Internal stakeholders and end users selected a modern-looking, fresh design with the option of using different background colors, to fit with different hardware designs.

Visual design - Background 1   Visual design - Background 2   Visual design - Background 3   Visual design - Background 4
