“

Lk” and “OFF” (default, keypad not locked out). The 

 and 

 are used to toggle the selection between 

OFF and “L” (keypad locked out). When the keypad 

lockout selection is enabled 

“L”, and the MENU button 

is pressed again, the display will indicate the number 

“0” (default, still disabled) in the time digits. The 

 

and 

 are used to set the combination number from 

0 

to 

999. If a combination of 0 is selected and the MENU 

button is pressed, the menu will be exited and keypad 

will not be locked. If 

1 to 999 is selected and the MENU 

button is pressed, the combination is stored into memory 

and the menu is exited. The “

Lk” will display designating 

keypad locked with a valid combination. The SYSTEM 

button will operate for 10 seconds after the menu mode 

is exited to allow the user to change the mode from 

“

OFF” to the desired SYSTEM mode.

 

While the keypad is locked out, a press of MENU will en-

ter the configuration menu. The first menu item displayed 

is the combination code “

0”. The 

 or 

 keys are 

used to set the combination unlock number from 

0 to 

999. If the unlock number matches exactly with the com-

bination lock number stored in memory when the MENU 

button is pressed, the keypad is unlocked and the 

“Loc” 

is removed. If the unlock number does not match when 

the MENU button is pressed, the combination returns to 

“0” for another attempt to set the unlock code. To exit the 

menu without unlocking the keypad, press RUN SCHED.

 

To reset the combination code and unlock the keypad if 

the code is forgotten, see troubleshooting section.

Select Reversing Valve Output (SS/HP switch must be set 

at HP, omitted if SS/HP switch is SS Position) – The O/B 
option is factory set at "O" position. This will accommodate 
the majority of heat pump applications, which require the 
changeover relay to be energized in COOL. If the thermo-
stat you are replacing or the heat pump being installed 
with this thermostat requires a "B" terminal, to energize the 
changeover relay in HEAT, the O/B option should be set at 
"B" position.

To enter the Configuration Menu, SYSTEM must be set to 

HEAT, COOL, Em or AUTO. Press the Menu button for at least 5 

seconds. The display will show item #1 in the table below. Press Menu button to advance to the next menu item. Press 

 or
