STATEMENT OF USE -
This thermostat can be used with all 24VAC and millivolt (24VAC external
power) heating and cooling systems. It cannot be used with line voltage systems. This thermostat is
digital and your desired heat or cool temperatures can easily be set on the large touch screen with the
+/- buttons. A minimum 4 minute off time protects heating and cooling compressors from damage.
This thermostat uses a new technique called sequential staging for more comfort with faster reaction
to requested temperature changes.
24VAC is Required
-
This thermostat can run on the HVAC system’s 24VAC common “C” wire or an external adapter 12V
to 24V AC or DC connected to the C and RH (no polarity). The 24VAC “C” wire is the other side of the
24VAC heating transformer and can be found where the other thermostat wires connect at the wall or
at the furnace.
Do not
use the common or ground side of the line voltage.
