Yes, to lockout the keypad you will need to change the dipswitch settings. To do this remove the faceplate from the backplate. On the back of the faceplate you will find a series of switches, locate the switch labeled "locked/unlocked". Flip the switch to the locked position and replace the faceplate back onto the backplate. This will disable all buttons on the keypad except for the up and down arrows. Pressing the up or down keys will allow a change of +/- 6 degrees for one hour.
