How your system works

Cooling cycle
During the cooling cycle, your system removes heat and
humidity from your home and transfers this heat to the
outdoor air.
System operation
Your thermostat gives you full control of the cooling levels
in your home, and enables you to control these remotely
using a smart device. Do not switch your thermostat on
and off rapidly. This may damage your equipment.
User's Information Manual: HMCG2 Series - 16 SEER2 Horizontal Discharge Modulating Air Conditioner
Setting the thermostat
The main power to the system must be kept on
at all times to prevent damage to the outdoor unit
compressor. If necessary, use the thermostat control
switch to turn the system off. Should the main power
be disconnected or interrupted for 8 h or longer, do not
attempt to start the system for 8 h after the power has
been restored to the outdoor unit.

Thermostat

Your key to comfort
Although thermostats may vary widely in appearance, they
are all designed to perform the same basic function: to
control the operation of your air conditioning. Regardless
of size or shape, each thermostat features the following
items:
• a temperature indicator
• a dial, arm, or push button for selection of the
required temperature
• a fan switch to choose the indoor fan operation
Note: Only approved thermostats have been tested
and are fully compatible with this equipment. Many
different thermostats operate on batteries or power
stealing principles. These types of thermostats
cannot be supported as trouble-free when used with
this product.
A complete operating instruction is provided by the
manufacturer for each thermostat. Familiarize yourself
with its correct operation to ensure maximum comfort
with minimum energy consumption.
A computerized electronic thermostat includes features
that enable set-back temperature variations for nighttime
or periods when you are away from home during the day,
reducing energy costs. The thermostat also features a
digital clock.

Start-up

Observe the maximum and minimum conditions for
