INTRODUCTION  
The Legacy Line -- RNC Series thermostat is an electronic 24VAC,  
non -- programmable, manual changeover wall mount thermostat.  
This thermostat uses a single setpoint to maintain and control room  
temperature in both the heating and air conditioning modes. The  
thermostat is designed to maintain +/ -- 2_F accuracy. No batteries  
are required; temperature, fan, mode, and installer configuration  
settings are preserved with power off.

T1 -- NAC, Legacy Line -- RNC Series Model air conditioner  
thermostat, may be wired with or without connecting a common  
wire between the indoor equipment and the thermostat. However, it  
is recommended to use a common wire whenever possible.  
Without a common wire this thermostat becomes “power stealing.”  
This means it will need to steal a small amount of power from the  
equipment to which it is connected.  
NOTE: Not all HVAC equipment is compatible with power  
stealing type thermostats. All Bryant equipment is directly  
compatible with this thermostat except the Thermostat Conversion  
Kit, Part #TSTATXXCNV10. For all non -- Bryant equipment,  
consult the system equipment Installation Instructions before  
applying this thermostat in a power stealing manner.

or use can cause explosion, fire, electrical shock, or other  
conditions which may cause death, personal injury, or property  
damage. Consult a qualified installer, service agency, or your  
distributor or branch for information or assistance. The qualified  
installer or agency muse use factory -- authorized kits or accessories  
when modifying this product. Refer to the individual instructions  
packaged with the kits or accessories when installing.  
T1 -- NHP, Legacy Line -- RNC Series Model heat pump thermostat,  
is compatible with all Bryant heat pump systems. It is NOT power  
stealing and MUST have both the R and C terminals connected to  
operate properly. This thermostat uses a green LED to indicate  
auxiliary heat and emergency heat operation.

Available Selection:  
output is turned on for 9 minutes and then satisfies, it cannot turn  
back on for another 6 minutes regardless of demand). However,  
pressing UP and FAN buttons simultaneously or changing the  
setpoint will override the timer for 1 cycle.  
Use UP and DOWN buttons to change between F and C.  
Option 04 — G (fan) ON with W (Heat) Selection  
This selection determines whether G (fan) output is to be ON or  
OFF when W (furnace or strip heat) output is ON. Most furnaces  
and fan coils manage their own blowers and do not require a  
separate G signal. For these applications, select OFF. Some  
auxiliary heaters require a separate G signal from the thermostat to  
turn on the blower. In this case, select ON. Factory default is OF  
Minimum on Timer  
Once the equipment has turned on, it will remain on for a  
minimum of 3 minutes regardless of demand. However, the  
equipment can turn off in less than 3 minutes if a change in  
setpoint or a change in mode occurs.  
Staging Timer  
(off).  
If the thermostat is a heat pump model, it has 2 -- stage heat  
capability. With HP operation, there is a 15 -- minute delay between  
the first and second stages of heat. The Y output will energize first,  
then 15 minutes later, W is allowed to come on if the thermostat  
determines it is not satisfying the demand.  
Available Selection:  
Use UP and DOWN buttons to change between ON and OFF.  
Option 10 — O (reversing valve) On with Heat or  
Cool Selection  
This selection is only available on heat pump model thermostats.  
This selection determines whether the reversing valve is energized  
in the heating or cooling mode. Factory default is C.  
However, if the heating demand is greater than 5_F, there will be  
only a 30 second delay before bringing on W.  
Auxiliary Heat Indicator  
Available Selection:  
A green LED indicates the use of auxiliary heat or emergency heat.  
Error Messages  
Use UP and DOWN buttons to change between H and C.  
Option 13 — Room Temperature Offset Adjust-  
ment  
This option allows calibration (or deliberate miscalibration) of the  
room temperature sensor. There are various reasons why  
homeowners may want to have displayed temperature adjusted to a  
higher or lower value. The selected number is the number of  
degrees, plus or minus, which will be added to actual temperature.  
 -- -- ” (two dashes) will be displayed if the thermostat cannot  
properly read room temperature. If “ -- -- ” appears, replace  
thermostat.  
E4 will be displayed if the thermostat has an internal memory  
failure. If E4 appears, replace thermostat.  
Step 5 — Check Thermostat Operation  
Fan Operation  
The numbers can range between -- 5 and +5. Factory default is 0.  
1
. Press FAN button. This will start continuous fan operation.  
FAN annunciator will turn on.  
Available Selection:  
Use UP and DOWN buttons to now move between -- 5 and +5 in  
increments of 1.  
2. Press FAN button again. This will stop continuous fan oper-  
ation. FAN annunciator will turn off.  
Step 4 — Thermostat Operation  
Heating Operation  
Temperature Display  
1. Press H/C button until HEAT is displayed.  
Thermostat will display room temperature until UP or DOWN  
button is pressed. The word SET appears when these buttons are  
pressed and the current setpoint is displayed. If no buttons are  
pressed for 5 sec, the display will change back to show room  
temperature.  
2. Press UP button until LCD readout reads 3_F above room  
temperature. Press UP and FAN buttons simultaneously to  
defeat timers. Heating system should begin to operate im-  
mediately.  
3. For HP thermostats only, press H/C button until EMHT  
(emergency heat) appears. Press UP and FAN buttons sim-  
ultaneously to defeat timers. Emergency heating (W is ON,  
Y is OFF) should begin immediately.  
Timeguard Timer  
A 5 -- minute timeguard is built into the thermostat immediately  
upon power up, and any time the compressor turns off. The  
compressor will not turn on until the timeguard has expired. The  
timeguard affects only compressor operation. Pressing UP and  
FAN buttons simultaneously will override the timeguard for 1  
cycle. With PH or PC selected under Option 01, this timer is  
defeated.  
Cooling Operation  
1. Press H/C button until COOL is displayed.  
2
. Press DOWN button until LCD readout reads 3_F below  
room temperature. Press UP and FAN buttons simultan-  
eously to defeat timers. Cooling system should begin to op-  
erate immediately.  
Cycle Timer  
In normal heating and cooling operation the thermostat will not  
allow more than 4 equipment cycles per hour (or 1 cycle every 15  
minutes). Both the Y and W outputs have a 15 -- minute timer that  
starts counting down when the output is turned on, (e.g., if Y  
Table 1 shows the thermostat outputs for each available stage of

. To Select the Fan Operation:  
Use the FAN button to move between continuous fan (in-  
dicated by the FAN ON icon) and auto fan operation.  
. To Read the Room Temperature:  
The large display reads room temperature until a button is  
pressed.  
. To Adjust the Setpoint:  
In normal operation, the large display shows room temper-  
ature. At the first press of the UP or DOWN button, the  
large display shows the current setpoint and the SET TEMP  
icon is turned on. Further presses of the UP or DOWN but-  
ton adjust the setpoint upward or downward. Five seconds  
after the last button press, the display returns to the room  
temperature and the SET TEMP icon turns off.  
TROUBLESHOOTING  
What if there is a green light on in the upper  
corner of the display area?  
This thermostat uses a green LED to indicate auxiliary heat and  
emergency heat operation on the Heat Pump model. This green  
light means one of two things.

. Auxiliary Heat is on:  
This light turns on automatically when the system determ-  
ines that it’s too cold outside for your heat pump to heat the  
house without help. So, it’s getting help from the electric  
heaters.  
NOTE: This indicator does not reflect a problem with your  
system.  
2
. Emergency Heat is on:  
If the heat pump is not working properly, you can manually  
select the emergency heat for extra help in heating. You’ll  
know there’s a problem if the house can’t seem to get warm  
when it’s cold outside.  
You want to avoid using emergency heat, though, because  
it’s the most expensive option. And, of course, if you sus-  
pect a problem with your heat pump, call your heating and  
cooling dealer immediately.
