Factory default control parameters
The parameters used in the controller have been developed by Accurate Thermal Systems to give the best unit
performance for most applications. If the need arises the “AT” autotune command can be run to further optimize
results based on the thermal block load and ambient conditions. Contact us for further support and details.
