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.

Getting to Know Your Thermostat
The thermostat has a display, a covered 15 key
keypad, a covered battery compartment, and
an indicator light on the front panel (see Fig. 2).
Fig. 2 shows the thermostat, display, and all
display segments.

Thermostat.
Standard Display
The current room temperature and time are
always part of the standard display. Other
displayed data includes heating and air
conditioning (Heat/Cool) status, day of the
week, schedule period, water heater and
appliance status, and the RSVP current price
(see Fig. 2). The thermostat display automati-
cally sequences several displays (see Fig. 3).
NOTE: The colon in the time display blinks,
except when in the programming
mode.

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.
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.
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.
Replacing Thermostat Batteries
IMPORTANT
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: If the time is ever incorrect, you can
not change it. Your energy utility
periodically updates the clock to the
correct time.

969-1611
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:
1. Use a coin to carefully remove the
battery door (see Fig. 4).
2. Follow the directions on the label
revealed by removal of the battery door. Fig. 4. Battery Door Removal.
