The Digital Thermostat That Builds
Your Business And Flexes Your Inventory.
The vertical 70 Series™ thermostats build your new construction
business. It's the first series of flexible thermostats enabling
customers to wire and mount one subbase for use with the temporary
new construction thermostat and easily snap on an upgrade to any
1E78 digital model upon building completion. The vertical 70 Series
low-profile design blends narrow width with new home decors.
The universal subbase, for use with all 1E78 models, is designed
to mount on a 2" x 4" junction box or directly to the wall. There is also
an optional wallplate for use in retro-fit applications. The 70 Series
thermostats are battery powered, making them easy to install and
compatible with most heating and cooling systems. The vertical
70 Series is perfect for new construction customers who want
a quick and easy transition to job completion.
