Understanding Additional Features
•
Advanced Recovery Mode:
This feature minimizes the time required to achieve a comfort setting after a
set back period. During normal operation, the thermostat will gradually change to the set point temperature
prior to the actual program time. Advanced Recovery Mode ensures that the room is at the desired temper-
ature at the desired time by intelligently initiating the temperature adjustment in advance. Note: This fea-
ture can be deactivated by changing the ARM switch on the circuit board to off.
•
High Temperature Protection:
While in the
HEAT
position, if the room temperature reaches 93 F (34 C),
the thermostat will automatically shut off. In the unlikely event the room temperature reaches 99 F (37 c), a
mechanical bimetal switch will shut off the thermostat.
•
Low Temperature Protection:
While in the
HEAT
position, if the room temperature drops below 40 F (4
C), the thermostat will automatically initiate a call for heat.
•
Compressor Protection:
To protect the system compressor(s) from damage, the thermostat features a 5
minute delay. After the cooling system (or heat pump) turns off, the thermostat will not allow it to re-start
until the 5 minute delay expires. A blinking snowflake/flame indicates this feature has been activated.
Once the 5 minute delay expires, the snowflake/flame will illuminate continuously and the system will be
able to re-start when called upon.
NOTE:
For the purpose of unit installation, this delay can be overridden by
depressing the
RESET
button. This will erase any programmed settings.
•
System Reset:
The thermostat can be reset to factory software settings including the program. All user
entered settings will be lost. The reset will also override the 5 minute compressor protection feature. To
reset the thermostat, gently press the reset button on the front panel using a paper clip or similar small
pointed object.
