ELECTRIC HEAT - Selecting Electric Heat on, page 7,
step 6, will cause the thermostat to turn on the fan
immediately
any time there is a heat demand. Since all
gas furnaces
control the fan, this feature should be off
unless the heater
is only electric.
KEYPAD LOCK - To prevent unauthorized use of the thermostat,
the front panel buttons may be disabled. To disable, or

About Advanced Features & Operation
DUAL SETPOINT BEHAVIOR - The adjustable setpoint range
is: 35 - 99 degrees in Fahrenheit and 7 - 35 degrees in
Centigrade. When in the modes Heat or Cool, this
adjustable range is unhampered.
When adjusting any Auto mode, including programming
Occupied and Unoccupied periods, the 1050 will not
allow the Heat setpoint to get closer to the Cool setpoint
than the value programmed as the minimum difference in
step 7, page 13.
When entering the Auto mode from Cool, the Heat and
Cool setpoints will remain spread apart by the amount
that they were adjusted, prior to entering Auto.
For example: If the Cool setpoint was set to 80 while
in the Cool mode and the Heat setpoint was adjusted to
70 while in the Heat mode, upon entering the Auto mode
the Heat and Cool setpoints would be 80 and 70. Both
setpoints would then move up and down together, (in this
example spread by 10 degrees), by pressing the up or
down buttons.
To move the Heat and Cool setpoints closer together,
enter the Cool or Heat mode by pressing the Mode button,
then adjust the setpoint(s) closer together. Heat is limited
to how close it can come to Cool by step 7, page 13.
FACTORY DEFAULTS - If, for any reason it is desirable to
return all stored settings back to the factory default
settings, press the Mode button. While holding the Mode
button in, press the Down button for 5 sec. All icons will
appear. Press and hold in the Fan button until Fd
appears. This resets all factory settings. To calibrate
room temperature, press the Mode button once more.
At this point use the Up and Down buttons to calibrate
room temperature, if needed. Press the Mode button to
return to normal operation. NOTE CAUTION ON PAGE 1.
