IMPORTANT SAFETY INFORMATION
WARNING:
• Always turn off power at main fuse or circuit breaker panel before
installing, removing, cleaning, or servicing thermostat.
• Read all the information in this manual before installing this
thermostat.
• This is a 24V AC low-voltage thermostat. Do not install on voltages
higher than 30V AC.
• All wiring must conform to local and national building and electrical
codes and ordinances.
• Do not short (jumper) across terminals on the gas valve or at the
system control to test installation. This will damage the thermostat
and void the warranty.
• Do not connect ground to any terminal in this unit.
• This thermostat is configured with automatic compressor protection
to prevent damage because of short cycling or extended power
outages. Short cycle protection provides a delay between heating
and cooling cycles on heat pumps.
Detailed mounting and wiring instructions are explained in the
Installation Manual.
Refer to the Pop-Up Wizard section in the installation manual for a
complete list of factory defaults and contractor settings.
Providing Power to the Thermostat
For wiring diagrams refer to the Installation Manual.

Emergency Heat
Your system may include Emergency Heat. The RS5220C thermostats
have an emergency heat capability for multi stage heat pump systems.
To determine if your system is capable of using emergency heat contact
your contractor. Use the button to enter the EMER mode. An E will
be displayed with the Heat symbol. This mode is used to bypass the
heat pump when it needs servicing or when it cannot keep up with the
heat demand.

5
Auto Changeover
Auto changeover is the ability of the thermostat to switch automatically
between heating settings and cooling settings. This is useful in Spring
and Fall when the days are warm and the nights are cool. In heat mode
if the room continues to warm beyond a set threshold the thermostat
switches to the cool mode and the associated cooling settings. The
reverse is also true.
As the room temperature changes, the thermostat will call for heating or
cooling as needed. To prevent the heating and cooling systems from
overriding each other, an auto changeover deadband is used.
The deadband is the minimum temperature swing before changing from
heating to cooling or vice versa. The larger the deadband the more the
room temperature will vary.
Operating the Thermostat
Any setting can be changed when it is flashing by pushing or
If a button is not pushed for 10 seconds the thermostat returns
to operation.
The following buttons can be accessed from the front panel.
START/STOP SCHEDULE: Switches between running a schedule and
manual (permanent override). Cancels a temporary override.
EDIT SCHEDULE: Use this button to start editing the schedule. Push
repeatedly to move through the selections.
VACATION: Used to set a temporary setpoint for a number of days.
SET TIME: Sequences through the hour, minute and day.
LIGHT BAR: Turns on the display back light for 10 seconds.
FAN: Turns fan to AUTOMATIC, CIRCULATE or ON.
UP ARROW: Raises the setpoint or increases flashing item.
DOWN ARROW: Lowers the setpoint or decreases flashing item.
HEAT/COOL: Toggles through OFF, HEATING, COOLING, and AUTO.
If configured as HP then emergency heat is also displayed.

When and are pressed at the same time the thermostat will
display the current settings in order.
To change any setting:
When the setting is visible and flashing press the or
arrows to adjust the number on the screen.
To exit the changes and save:
Press START/STOP SCHEDULE. The thermostat will return
to operation.
SCAL = Scale in °F (Fahrenheit) or °C (Celsius).
CLOC = Set clock to 12 or 24 hour format.
LITE = Display backlight always on ”y” or off ”n”. Also called the
nightlight feature. If the thermostat has been wired with 24V AC
(R and C terminals) then this feature will be displayed and the
setting can be changed.

8
DIFF = The differential keeps the thermostat from turning on for small
changes in temperature. When in Fahrenheit the range is 0.5 to
3.0 Degrees. In Celsius the range is 0.5 to 1.5 Degrees. The
differential is factory set at 1.0 °F (0.5 °C). This means that
whenever the room temperature is more than 1 °F (0.5 °C)
different from the set temperature the system will turn on. If the
system is turning on too often, increase the differential setting.
Note that a larger differential will mean the room temperature
changes more before the system turns on.
DIF2 = Second Stage Differential = Operates with the first stage to
control a second heating/cooling system. This number will be
added to the first stage differential (See: Two Stage Systems).
If the first stage is running too often lower the settings. This will
turn the second stage on to help the first stage. If both stages
are coming on too often then increase this setting to delay the
second stage.
DLY2 = Second Stage Delay = This timer starts when the first stage turns
on. It resets when the first stage turns off. If this timer runs out
the second stage will turn on (See Two Stage Systems).
Auto changeover enable = Makes the auto changeover mode available.
When chosen, the thermostat can automatically switch between
heating and cooling. Note that the High and Low setpoint limits
are not enforced in auto changeover mode.

9
DEDB = Deadband for auto changeover = the number of degrees that the
room temperature can move away from the active setpoint until
heating or cooling is called for. The larger the deadband the
more the room temperature will vary. This can be from heat to
cool or cool to heat.
HI = High Heat Limit = This is the highest allowed heating setpoint. The
user will not be allowed to set a schedule setpoint or override
temperature higher than this value.
NOTE: High Heat Limit is not enforced in auto changover mode.
LO = Low Cool Limit = This is the lowest allowed cooling setpoint. The
user will not be allowed to set a schedule setpoint or override
temperature lower than this value.
NOTE: Low Cool Limit is not enforced in auto changover mode.
VAC HEAT = Vacation Heat Setpoint = This is the temperature setpoint
for the heating system when a vacation override has been
made active.
VAC COOL = Vacation Cool Setpoint = This is the temperature setpoint
for the cooling system when a vacation override has been
made active.

10
CHECK = Timer to remind the home owner to maintain the filter. Default
setting is off. The timer runs when the system is on. It can be
set at 0 (OFF) or up to 9900 hours. When the time expires
CHECK FLTR is displayed. Press the and buttons to
restart the filter timer.
CYCL = Cycle Timer allows a compressor to rest between cycles. Can be
set from 0 to 5 minutes in 1 min increments.
WARNING: A wrong short cycle setting can
damage your equipment. This should only
be changed by a trained HVAC professional.
CAL = Calibration offset. Changes the displayed temperature from the
actual temperature by +3 to -3 degrees in one degree increments.
Increasing the offset by +2 will cause the thermostat to display a
temperature that is 2 degrees higher than the actual room
temperature
Creating a Password – Protect the Settings
The buttons on the front of the thermostat can be locked with a password.
To create a password:
1. Press the and buttons at the same time and hold them in
for 5 seconds.
You will be asked for a 4 digit password.
2. Each digit is set using the and buttons. Press the to
move to the next digit. Press to move back.
3. The password is saved after 5 seconds.
All of the front buttons are now locked out until the password is entered.
Pressing any button will cause to flash.
To unlock the buttons:
1. Push and hold the and buttons for 5 seconds until the
request for password is displayed.

11
2. Enter the digits for the password by pressing the and
buttons. Press the to move to the next digit. Press to
move back.
3. When the correct password is set, wait for 5 seconds to unlock
the system.
4. If the wrong password is entered the display will flash ---- for 5
seconds then return to normal.
Once the security has been disabled, a password needs to be recreated
to protect the settings.
Two Stage Systems
A 2nd stage is a second or additional system
that will provide extra heating or cooling. When
a 2nd stage is operating the display will show
the number 2 by the heat/cool icons.
A temperature differential (default value is 2.0 °F or 1.0 °C) and time
delay (default value 20 minutes) control the 2nd stage cycle.
Operation of the 2nd stage begins when:
• The room temperature changes from the setpoint by the sum of the
1st and 2nd stage differential settings.
• The first stage has been on for the specified delay time, but the
heating/cooling demand has not yet been met.
Energy Efficient Recovery
With Energy Efficient Recovery, the thermostat “Looks Ahead” to the
next event and attempts to reach the next setpoint at the exact time of
the event. If you have two stages, the thermostat will use only the first
stage during this period. This is more efficient than waiting until the
next event and then turning on both first and second stages.
Backlit Display
This thermostat is equipped with a backlight to make viewing the display
easy. Press the button to activate the backlight. The backlight will
turn off after 10 seconds of inactivity. If the thermostat is wired to have
the backlight stay on all the time the night light can be turned on/off in
the settings menu.
Overriding the Schedule Settings
When the thermostat has been programmed, the settings and the
schedule are saved. The thermostat will run to the schedule unless an
override is entered.
Two methods of override are available.
Permanent Override
Press START/STOP SCHEDULE until the word SCHEDULE is not shown
on the display. A Permanent Override allows the thermostat to maintain
a setpoint indefinitely. To switch between Schedule and Permanent
Override, press START/STOP SCHEDULE button. Press or to
change the setpoint. The heat or cool mode should be selected.

12
Temporary Override
When the thermostat is running to a schedule, an override allows the
thermostat to function with a single setpoint for a time period.

1. Press or to display the flashing setpoint and the number
of hours.
2. Use and to change the setpoint.
3. Press SET TIME to move to the hours.
4. Use and to set the length of the override.
After 5 seconds the thermostat will start operation of the override. The
display will show room temperature, and the setpoint will alternate with
the number of hours remaining in the override.
The schedule will resume after the programmed override time expires.
Cancel the override by pressing START/STOP SCHEDULE.
Vacation Override
This override is programmed by pressing VACATION. The number of
days will flash.
Use and to change the number of days.
After 5 seconds the thermostat will begin operation of the vacation
override. The display will show room temperature and the setpoint will
alternate with the number of days remaining in the override.
Use and to change the setpoint. This will become the new
setpoint for future vacation overrides.
Cancel the override by pressing START/STOP SCHEDULE.
Determining Operating Setpoint
When the thermostat is using a schedule the temperature setpoint
originates from the schedule settings.
When one of the schedule overrides is active the setpoint has been
entered as part of the override.
Use the display to determine the origin of the current temperature setpoint.

13
Permanent Override – The day, time and “schedule” are not displayed.
Vacation Override – Vac and For are displayed. The clock shows days
of override. The display alternates days of override with setpoint.
Temporary Override – The display alternates hours of override with
setpoint.
Automatic Shut-Down
