Can this remote be programmed restrict how low the temperature can be adjusted but still show lower temperatures on the remote control? In other words the remote will show a temperature setting of 16 degrees C but the AC unit will not go below 21 degrees C? Are these settings tamperproof? Does it have a countdown timer capability to shut the A/C off after an adjustable time period or at a certain time of day? Is it fully compatible with all mini-split type air conditioning units? Does it come with a wall mount and a screw to secure the battery compartment cover? Are you able to ship to Mexico? What would you estimate the costs to be to ship 1000 units to Mexico? Thank you.
