Y2K COMPLIANCE
All Y ork thermostats and system control
boards for the Stellar™ series are Y2K
compliant.
THERMOSTATS
YOUR KEY TO COMFORT
Though thermostats may vary widely in
appearance they are all designed to
perform the same basic function, to
control the operation of your air conditioning system. Regardless of size or
shape, each thermostat will feature a
temperature indicator; a dial, arm or
push button for selection of the desired
temperature; a fan switch to choose the
indoor fan operation; and a comfort
switch for you to select the system
mode of operation.
Only York approved thermostats have
been tested and are fully compatible
with York designed equipment.
be aware that many different thermostats operate on batteries or “power
stealing” principals. York can not support such models to be trouble free
when used with the Stellar series units.
The following illustrations and discussion will aid you to determine which type
of thermostat you have for your system.
A complete operating instruction is provided by the manufacturer for each thermostat. Familiarize yourself with its
proper operation to obtain the maxium
comfort with a minimum of energy consumption.
Please
COOLING ONLY
If your air conditioning system is
designed to provide cooling only, with
no capability for heating operation, a
one-stage cooling only thermostat, with
a manual, one-position “Cool” and “Off”
comfort switch is all that is required for
system operation.
NOTE: If you have an independent
heating system (with a separate thermostat), always be sure the heating
control is turned “Off” before turning on
the cooling system.
COOLING AND HEA TING
If your system has been designed to
allow both cooling and heating operation, you may have either a manual
change-over type, or a programmable
electronic type thermostat .
MANUAL CHANGE-OVER
Manual change-over simply means that
the comfort switch must be manually
positioned every time you wish to switch
from the cooling to heating or heating to
cooling modes of operation.
PROGRAMMABLE
ELECTRONIC
THERMOSTATS
The computerized electronic thermostat
is actually a sophisticated electronic
version of a manual change-over type.
This thermostat includes features which
allow “set-back” temperature variations
for periods of sleep, or while you are
away during the day , and means energy
savings for you. The thermostat also
features a digital clock.

FAN OPERATION SELECTION
A multi-position fan switch allows you to
choose the type of fan operation of the
indoor fan.
AUTO
With the thermostat fan switch set to
“AUTO”, the fan will run intermittently as
required for either heating or cooling.
This position will provide the lowest operating cost. If you purchased one the of
the York thermostats, they have an
Intelligent fan mode which continually
circulates the air during occupied
modes or when you are at home, and
