During Emergency Heat the thermostat will turn  
on the fan and the 2nd stage of heat, when there is a  
demand for heat, locking out the 1st stage compressor.

Emergency Heat only OFF and HEAT are available.

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  
‘
lock’ the keypad, press and hold in the Mode button.  
While holding the Mode button in, press the Up and Down  
buttons in together.

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  
7
0 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.
