Programming Thermostat  
Factory Set Programming  
The thermostat defaults to a normal non-  
programmable thermostat at power-up,  
indicated with Hold appearing in the  
display. Pressing the Prog key once enters  
the programming mode. The thermostat is  
preset with a factory set schedule for 7  
days, see Table 1.  
Initial Powerup  
When the thermostat is first powered up (or  
after eight hours of continuous power loss),  
the display blinks for two seconds and then  
undergoes a self-test — while 00E displays  
for about 15 seconds.  
This is followed by the display flashing  
(
1:00 PM); the internal checkout is

equipment time to adjust the temperature  
before you get up.  
Thermostat Reset  
The T4700 can be reset to its default  
settings (Table 1) by inserting a bent paper  
clip or similar wire into the small hole on the  
front of the thermostat (next to to the (+)  
key with the cover open). This resets only  
the clock; the programmed schedule is  
retained.  
LEAVE is the time you can set for an  
energy-saving temperature while you are  
away at work or school.

on the equipment after an energy saving  
period. When deciding what time to set for  
your RETURN period, include extra lead

the temperature before you arrive home.  
After programming is complete, the  
device reverts to normal Run mode  
within five minutes, if no key was  
pressed, and any new setting is  
stored in its memory.  
SLEEP is the time you can set for an  
energy-saving temperature while you are  
sleeping.  
The thermostat is flexible and can be  
programmed to meet your lifestyle. Four  
time periods are available:
