Incredible Digitals
When it comes to non-programmable temperature control, we
listened to the experts–YOU! Our new thermostats are the next
generation in digital control. The LCD display is clearly one of
the largest in the industry, up to 80% larger than competitive
models. Plus, the display is back lit, making it even easier to
read in a dark room.
The 9400 and 9401 are loaded with enhanced features. Our
permanent winter and summer setpoint memory allows you to
save both heating and cooling temperature settings. This
eliminates temperature adjustments when switching systems for
seasonal requirements. And our fully adjustable differential
provides increased comfort control. The 9400 comes with a front
load battery door, for no-hassle access to batteries. The 9401 is
equipped with a common wire for applications where line power
is preferred. Both are compatible with all standard 24 Volt AC
heating and cooling systems.
When you select a Robertshaw thermostat, you’ve made the
choice of an industry partner that’s been making quality
products for 100 years. Come home to affordable comfort.
