Just a warning - unless you can actually set two different temperatures with two different probes (I'm not familiar with this product), it will likely not be able to control two different heating devices accurately.

What thermostats do is raise/lower or turn on/off the power supplied to your heating devices based on the temperature the probe is sending them. If it has one probe, it will only transmit/receive one temperature reading. Unless it is connected to two identical heating devices, the heating devices will run at different power levels - still generating unbalanced, potentially, unsafe temperatures between them.

This may or may not be an actual problem - that's what a reliable temp gun or probed thermometer will tell you. Typically, out of an abundance of caution, it's recommended to have a separate thermostat for each different heating device.
