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
