No, but you can simulate it at the transmitter end with a loop instead of reading the temp sensor....duh!!!

Just set up the transmitter to send out a slowly changing temperature that goes up the scale, resets to the low end, climbs back up again, whatever works for you.
Or do it at the receiver end, put a couple of buttons in there, one button-temp goes up, another button-temp goes down.
