IMPORTANT: If you have labeled and connected your wires and followed the correct HVAC setup, and your system
still does not operate, contact technical support.
STATEMENT OF USE: This thermostat can be used with 24VAC heating and cooling systems and also millivolt
heating. It is powered by 4AA batteries, 24VAC (C wire), or 24VAC adapter. It cannot be used with line voltage
HVAC systems. This thermostat is digital and your desired heat or cool temperatures can easily be set with the
+/- buttons on the right side. In COOL and heat pump operation, an automatic 4 minute off-time protects the
compressor from damage.
This thermostat runs on 4AA batteries. The CT110 can be externally powered with a power source rated from
12V to 24V, AC or DC, at 100ma or greater. If used, connect to the C and RH terminals (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.
