Q-Mode
®
The industry’s fi rst and patent pending Q-Mode
®
delivers four
modes of operation to deliver the highest effi ciencies across
all AHRI rating points.
Q-Mode
®
(4-modes) include:
• Space
Cooling
• Space
Heating
•
Hot water while space cooling
•
Hot water only operation
What makes Q-Mode
®
unique and patent pending is it’s
ability to heat hot water during cooling AND ability to
generate hot water while not space heating/cooling to deliver
year-round, full-time, on-demand hot water.
Particularly impressive is the fact that in hot-water during
cooling mode, the heat from the home is transferred to
the tank and NOT to the loop. It’s free space cooling while
heating water.

While Trilogy
®
’s 45 EER and 5.1 COP are impressive, what
sets it in a league of its own is the ADDITIONAL savings
of full time hot water produced by the heat pump at up to
5.0 COP. This results in over 80% savings in hot water
production vs. an electric water heater and 50%+ savings vs.
the next best heat pump.
