IMPORTANT: If you have both an RC and RH wire present then
remove the RED RC-RH shorting cap found on inside front of GEOTM.
Wiring is complete - you may return “cover” between terminal blocks.
GAS / OIL / ELECTRIC FURNACE and/or AIR CONDITIONING [typical wire color used]
(typical)
RH (or R) = 24(+) VAC Power, Heat [RED]
W1 = 1st Stage Heat [WHITE]
G = Blower Fan [GREEN]
C = 24(-) VAC Common [BLUE]
Y1 = 1st Stage Cool [YELLOW]
(other)
RC = 24(+) VAC Power, Cool
B = Heat Mode Damper
O = Cool Mode Damper
W2 = 2nd Stage Heat
Y2 = 2nd Stage Cool

*Notice for battery installations:
Batteries should be replaced at least once per year, but
depending on your settings may need to be replaced sooner.
Battery failure could leave property without controlled
heating or cooling. Reliance on battery power is not
recommended with prolonged absence from property.
After installation you can choose to set the
“energy profile” for your GEOTM This energy profile will
determine the delay in GEOTM responding to changes from
the App.
GEOTM should only be used with lithium batteries.
