The design of the Pro1 thermostats have been carefully crafted to inspire a contemporary look. The white matt plastic complements the blue backlight to give the ultimate sense of control to your HVAC unit. The thermostat works well with all the major heating brands and add on cooling units. All Pro1 thermostats are low voltage or battery operated. Pro1 thermostats do not work with evaporative cooling units.
