Ebo Jager heater operation?

I purchased a new Ebo Jager TS heater (250W, 105 gallon tank) - I've got the
heater set to bring the tank to 79.5 degrees - I'm used to seeing heaters
run (the red light stays on) until the tank is at the desired temp, then
cycle on and off as necessary - this heater is cycling on and off even
though the tank is not at 79.5 degrees - two different thermometers show the
tank at 77 degrees - is the heater working as designed and it'll just take
longer to get the tank to the desired temp, is does there appear to be a
problem? Thanks!

sounds normal to me. The water directly around the heater may be at the
desired temp however changes as water flows around it. One heater of that
size in a 105 gallon tank will likely cause it to cycle on and off quite a
bit. You might have been better off with say two 150 watt heaters, one at
each end of the tank which would give more uniform heating.
