A CHE doesn't need a thermostat, certainly not a high end thermostat. a lamp dimmer or cheap thermostat like the hydrofarm will be more than good enough.
I prefer infrared heat lamps to CHE's but I would still recommend a lamp dimmer ($10-$15)

or

The thermostat will automatically adjust to the new heating equipment, that is the beauty of a thermostat.
