Gary,
I think it depends on what temp you want to maintain in your reef, the spread on the chiller thermostat sepoint, and the temperature you keep the room the reef is in at. The lower your setpoint on the chiller, the more it will come on. The higher your ambient room temp, the more often the chiller will come on, and the greater the setpoint spread on the chiller, the less often it will kick on. If the t'stat setpoint spread is +1 degree it comes on more than if the spread is +2 or +3.
If it comes on and stays on for an extended period, then I would look at the issue, but a few minutes every hour or so sounds OK to me.
