What do you mean by under tile?

I think that it would be best to either get 2 thermostats, or a thermostat with 2 probes so that it can control both temps at the same time.
The Herpstat 4 should do that, or the Vivarium 300 Dual Zone.
The herpstat 2 has two probes and can control two different heat sources.
