Power-up

At power-up, the thermostat's LCD shows all display
segments for two seconds, enters a self-test mode for a
few seconds, and then displays the current room
temperature (default screen), as shown in Fig. 23.
NOTE: If there is a temperature sensor failure or the
temperature is outside of the operating
range, the room temperature display shows
two dashes,
When the sensor returns to its operating
range, the temperature display resumes.
CAUTION
Equipment damage hazard.
Power overload will damage the thermostat.
The thermostat has a safety fuse rated at 15 A/
250 Vac. If the fuse blows, the thermostat must be
replaced. The fuse is not field replaceable.
This fuse is provided as a safety feature to prevent
fire if the thermostat is overloaded.
