Controlling both heat from above and belly heat.

Question: 
Can a single output Herpstat be used to control both heat from above and belly heat? 

Answer: 
Controlling top and bottom heat off a single output thermostat should be avoided because you only have one probe. So if you place the probe on the floor then the top heat could be too hot for the animal and if you place the probe on the top then the floor could be too hot. For both top and bottom heat you really need a dual output thermostat like the Herpstat 2 or Herpstat 4 and control the heat elements individually.
