I copied this awhile back from someones post:How to set the temp:
No idea if this still works or not.
Press the power button and the down arrow button simultaneously. The letters "bp" should appear in the display indicating you are in "bypass" mode. Then you can use the up/down buttons to set the temperature. You may have to do this every 24 hours or every few days.
The sensor by-pass for our kind of thermostat was simple--I just pressed the "off" button and both the temperature "up/down" buttons all at the same time. "BP' appears in the thermostat, and then it operates as most other themostats in most other hotels in the US
And yet another:
The thermostat has two buttons on the left (ON/OFF and AUTO/FAN) and two buttons on the right (UP and DOWN)
1) Press the ON/OFF and AUTO/FAN buttons together. The digital display will change to 'CA'.
2) Press the ON/OFF and DOWN button together. The digital display will change to 'OR" (or something similar).
You have just deactivated the motion sensor. This will last for three days at which point you will have to repeat the process.
TO CHANGE AC THERMOSTAT SETTINGS THE THERMOSTAT HAS TO BE PUT INTO "SERVICE MODE" IT IS SIMPLE TO DO BY PRESSING THE FOLLOWING KEYS ON THE FRONT OF THE THERMOSTAT.
EXECUTE THE FOLLOWING SEQUENCE:
1. PRESS (AND KEEP PRESSED) THE F/C KEY
2. PRESS (AND RELEASE) THE OFF/AUTO KEY
3. PRESS (AND RELEASE) THE DISPLAY KEY.
4. RELEASE THE F/C KEY.
UPON SUCCESSFULLY COMPLETING THIS SEQUENCE, THE LCD WILL DISPLAY PAR (PARAMETER) AND THE PARAMETER NUMBER.
1. PRESS THE UP ARROW KEY AND SCROLL UNTIL # 6 APPEARS. (NEW MODELS # 24)
2. PRESS THE OFF/AUTO KEY
3. THE CURRENT LOW TEMPERATURE IS DISPLAYED.
4. PRESS THE DOWN ARROW KEY AND SCROLL UNTIL THE DESIRED ROOM
TEMPERATURE APPEARS
5. PRESS THE F/C KEY
OKW
Thermostats at OKW are one of the easiest to override. Press and hold the F/C button on the left side of the thermostat. After 2-3 seconds bp will show on the display. The bypass will last for 24 hours so you need to do it every day. Pressing the F/C button will also change the display from Fahrenheit to Celsius. Just press it again to switch it back to whichever you prefer.
