Installaon and Operaon Manual
Wall Locaons
The thermostat should be installed approximately 4 to 5 feet above the oor. Select an area
with average temperature and good air circulaon.
Installaon Tip
Pick an installaon locaon that is easy for
the user to access. The temperature of the
locaon should be representave of the
room.
Do not install
thermostat in locaons:
• Close to hot or cold
air ducts
• That are in direct sunlight
• On an outside wall
• In areas that do not
require condioning

Thermostat Quick Reference
Wiring
This thermostat is shipped from the factory to operate a convenonal heang and cooling
system. This thermostat will also operate a heat pump system. See the “heat pump”
conguraon step on page 10 of this manual to congure the thermostat for heat pump
applicaons.
If you are replacing a thermostat, make note of the terminal connecons on the thermostat
being replaced. In some cases the wiring connecons will not be color coded. For example,
the red wire may not be connected to the R terminal.

Wiring Tips
Power Connecons
The thermostat can be either baery
powered, or hard-wired to power by
connecng supply voltage wire (red) and
common wire to the RH and C terminals,
respecvely, on the base.
Note: Installing baeries will enable the
thermostat to remember the program
that you have set even if there has been a
power outage.
Installaon Tip
Electrical Hazard
Failure to disconnect the power
before beginning to install this
product can cause electrical shock or
equipment damage.
Note:
When connecng the 6041228
thermostat to a PTAC, refer to the
PTAC unit’s instrucons to enable
remote thermostat operaon.
Wire Specicaons
Use shielded or non-shielded
18-22 gauge thermostat wire.
Remote Temperature Sensor
Connecons
Use the S1 and S2 screw terminals to
connect the oponal indoor remote
temperature sensor (Islandaire part no.
6040912). Indoor remote sensor wires
must be separated from the thermostat
wires.
Warning:
All components of the control
system and the thermostat
installaon must conform to
Class ll circuits per the NEC Code.

pump systems.
Cooling
Swing
The swing seng,
oen called “cycle rate”,
“dierenal” or “anci-
paon”, is adjustable. A
smaller swing seng
will cause more frequent
cycles and a larger swing
seng will cause fewer
cycles.
CoolSwing
The cooling swing
seng is adjustable
from 0.2° to 2°. For ex-
ample: A swing seng
of 0.5° will turn the
cooling on at approxi-
mately 0.5° above the
setpoint and turn the
cooling o at approxi-
mately 0.5° below the
setpoint.
