Welcome to the world of comfort and energy savings with your new Honeywell T7516A,B,C Energy  
Management Thermostat brought to you by your energy utility. This thermostat allows up to seven  
separate days of programming. You can set the thermostat to control the temperature in your  
home, your water heater, and another appliance (such as a swimming pool pump) according to  
your personal schedule and preferences. This thermostat keeps you comfortable, and saves you  
energy.  
Besides being programmable, this thermostat contains a communications module that allows your  
energy utility to communicate with your thermostat so you can take advantage of Residential  
Service Variable Price (RSVP) Rate.  
Residential Service Variable Price (RSVP) Rate. The T7516A,B,C Energy Management Thermo-  
stat informs you of the energy price in effect at any given time (see Fig. 1). A special feature of this  
thermostat allows you to program it to automatically adjust your energy use for each price. These  
prices are: Low (least expensive), Medium, High, and Critical (most expensive). The thermostat  
also provides you with the ability to operate your electric water heater and another appliance based  
on the price in effect.

Replacing Thermostat Batteries  
IMPORTANT  
Keypad  
Lift the front cover to see the keypad. From the  
keypad, you can operate and program the  
thermostat. To operate the thermostat, press  
and release the keys.  
Install batteries to maintain the time in  
the event of a power loss. Although  
the thermostat has a low battery  
indicator, replace the batteries once  
every two years to prevent the  
thermostat from losing the time during  
a momentary power loss.  
NOTE: The thermostat registers all program-  
ming inputs immediately and main-  
tains them until manually changed.  
Low batteries or power outages do  
not delete thermostat programming.  
NOTE: If the time is ever incorrect, you can  
not change it. Your energy utility  
periodically updates the clock to the  
correct time.  
Battery Compartment  
The battery compartment under the left side of  
the front panel contains two AA batteries that  
keep the clock running during a power interrup-  
tion.  
8
69-1611  
href="
As the batteries run low, the thermostat display  
sequence includes an indication of this. The  
low battery indication appears one to two  
months before the batteries run out completely.  
Replace the batteries as soon as possible after  
the indication appears.  
You need two AA alkaline batteries (not  
supplied); non-alkaline batteries do not last as  
long, and can leak, damaging the thermostat or  
wall surface. To replace the batteries:

(Tables 3 through 6) before you program your  
thermostat.  
You can program the thermostat with separate  
schedules for heat, cool, electric water heater,  
and one appliance (such as a pool pump).  
Each device schedule is for seven separate  
days and up to four periods. For convenience,  
you can program the seven days individually,  
or simultaneously in any one of the following  
groupings: Monday through Sunday, Monday  
through Friday, or Saturday and Sunday. The  
four periods are: Morning (MORN), Day (DAY),  
Evening (EVE), and Night (NIGHT).  
NOTE: If the heating and cooling are both off,  
the display will show Set - -.  
CAUTION  
Equipment Damage Hazard.  
Use of sharp fingernails or pencil  
points can damage the keypad  
beyond repair.

Recovery From Setback  
Recovery is the time when the thermostat  
operates the heating or cooling equipment to  
return the house from the energy savings to  
the temperature you prefer when you are  
present and awake.  
Only items being held appear on the  
display.

This thermostat uses a recovery process that  
turns your heating/cooling equipment on or off  
at the time you program the temperature to  
change. For example, if you set the thermostat  
to heat to 72°F at 6:00 AM, the heating  
equipment comes on at 6:00 AM and begins  
warming the house to 72°F. If you want the  
temperature in the house to be 72°F at 6:00  
AM, you must set the thermostat to turn on  
earlier; for example, 5:30. (The amount of time  
required to warm or cool your house to the  
temperature you want depends on many  
factors such as the size of your heating/cooling  
equipment and the outdoor temperature.)  
Programming Your Thermostat  
IMPORTANT  
Press and release the Present Setting  
key to exit programming and return to  
the standard display.  
NOTES:  
Energy prices supplied by your  
energy utility may influence the times  
you choose to schedule periods for  
maximum energy efficiency.  
Each period can occur at any pro-  
grammed time; for example, you can  
set morning at 9 PM. When you  
program the thermostat, be careful to  
use the correct time to avoid confu-  
sion.  
NOTE: If the thermostat is for a heat pump  
system, the thermostat uses a method  
of recovery that helps reduce the use  
of auxiliary heat.

69-1611  
MORN is the time you get up. Generally,  
you want the house at a comfortable  
temperature when you wake up. Set the  
MORN time earlier than your alarm clock  
so your home has time to reach the  
desired temperature.  
DAY is the time you leave for work or  
school. Generally, once you leave your  
home, you want the temperature higher  
or lower (depending on the season) so  
that you can save energy while you are  
away.  
EVE is the time you return from work or  
school. Again, you want your home at a  
comfortable temperature when you  
return and go about the normal activities  
of your evening. Set the EVE time earlier  
than the time you arrive so your home  
has time to reach the desired tempera-  
ture before you get there.  
NIGHT is the time you usually go to sleep.  
While you are sleeping, you can save  
energy by setting the thermostat to  
control the temperature higher or lower  
(depending on the season).  
If you choose not to program the thermostat, it  
controls the temperature using the following  
defaults:  
The cooling temperature remains set to a  
constant 78°F.  
At 6:00 AM every day, the thermostat sets  
the heating temperature to 68°F.  
At 10:00 PM every night, the thermostat  
reduces the heating temperature to 60°F  
You do not need to enter a time and tempera-

69-1611  
ture program for every period if your schedule  
does not require it; for example, if your home is  
occupied during the day on weekdays, you can  
program only the MORN and NIGHT times.  
As the cost of energy increases, the thermostat  
uses your pre-programmed choices to reduce  
usage by temporarily changing the setpoint;  
that is, it changes the temperature setting—  
increasing it for cooling, decreasing it for  
heating—or turns off the water heater and/or  
appliance.  
NOTE: You cannot set temperatures higher  
than 88°F or lower than 45°F.  
Price Response  
You can also program the thermostat based on  
the current price of electricity. Use Tables 7 and  
NOTE: You can enter the number of degrees  
you want the thermostat to change  
the temperature (offsets) for each  
price except Low. The Low price  
always uses whatever schedule  
programming exists and it is the basis  
for the offsets. The one exception is  
the water heater, which is always  
enabled during the low price.  
8
to plan the Price Response program.  
Price Response programming allows the  
thermostat to respond to changes in the RSVP  
prices. Your energy utility tells the thermostat  
what the current RSVP price is for electricity.  
These prices are: Low (least expensive),  
Medium, High, and Critical (most expensive).

NOTE: Before programming the thermostat,  
remove the clear protective plastic  
display overlay.  
CAUTION  
Equipment Damage Hazard.  
Use of sharp fingernails or pencil  
points can damage the keypad  
beyond repair.  
Entering Schedule Programming  
Refer to your Personal Programming Charts  
and proceed as follows:  
Use the ball of your finger or a soft  
pencil eraser when pressing the keys.  
IMPORTANT  
The thermostat registers all program-  
ming inputs immediately and main-  
tains them until manually changed.  
Low batteries or power outages do  
not delete thermostat programming.  
IMPORTANT  
When programming for the appliance,  
make certain that you consider  
potential safety issues; for example:  
with a pool pump during winter  
freezing weather, you will have to  
operate the pool pump as you have  
always done to prevent pump and  
pipe freezing.

69-1611  
NOTE: When setting a program time or  
temperature, the instructions direct  
you to “Press and hold until the  
display shows the desired time (or  
temperature).” This changes the  
setting quickly in the selected  
direction. Use this method when the  
change is large (for example, two  
hours, or ten degrees). Once the  
setting is close, press and release the  
key to move the setting one step at a  
time.  
IMPORTANT  
Because this procedure can affect up  
to seven days of programming, be  
careful when making changes with  
multiple days selected.  
NOTES:  
If you delete all programming with the  
CLEAR key, the thermostat uses the  
default program.  
PGM is an indication that you are in  
programming mode.  
Inputting Basic Program  
The most efficient way to program the thermo-  
stat is to first input a basic program for the  
entire week. Then, you can make changes to  
specific days to fit your needs.

Programming Price Response  
Overview  
Price response allows the thermostat to  
respond to changes in the RSVP prices. Your  
energy utility tells the thermostat what the  
current RSVP price is for electricity. These  
prices are: Low (least expensive), Medium,  
High, and Critical (most expensive). As the cost  
of energy increases, the thermostat reduces  
usage by temporarily changing the setpoint;  
that is, it changes the temperature setting—  
increasing it for cooling, decreasing it for  
heating—or turns off the water heater and/or  
appliance. If you do not enter any price offsets,  
the thermostat uses the default settings (see  
Table 2).

The Low Price Response settings are fixed and cannot be changed.  
Heat offsets are always negative (less heat to  
save energy). Cool offsets are always positive  
temperature to change from what you pro-  
grammed for normal operation to save money  
at each price. Think of the Price Response  
programming as what you are willing to give up  
to save money when RSVP prices increase.  
(
less cooling to save energy). Hot Water and  
Appliance settings are simply on or off.  
The offset entered is the number of degrees  
you are willing to allow the heating or cooling  
4

69-1611  
With an appliance, the APPL indicator lights  
with either an ON or an OFF indication. With  
APPL set to OFF at a particular price, when the  
price reaches that level, the appliance load  
turns off, ignoring the program schedule. The  
water indicator works identically to the appli-  
ance indicator with one exception: when the  
RSVP price is low the water indicator is always  
on.  
If you program an incorrect offset, press and  
release the Clear key. This changes the offset  
on the display to zero. The Clear key works for  
all programmable rates.  
Entering Price Response Programming  
Price Response programming is very similar to  
the other programming. One primary difference  
is that you can program the temperature offsets  
and water/appliance setting changes from the  
same display. The same water and appliance  
setting changes apply for both heating and  
cooling. Therefore, they need only be set once.  
Program them from either the heating or the  
cooling offset display. The following program-  
ming instructions—both heating and cooling—  
detail this process.  
NOTE: Price Response programming does  
not affect temperature, water, or  
appliance holds.  
For example, if you want your home heated to  
7
2° during low rate, but are willing to allow the  
temperature down as low as 70° during high  
rate, your heat offset for rate H (high) is -2  
(72° -2° = 70°). If you do not enter an offset,  
the offset remains as shown in Table 2.
