The controller may be operated by PC by installing a control module  and software included
There is a slight chance, the controller malfunction, it may go beyond the setting temp. So you can have another controller in series as back up. Both controllers connect to the same thermocouple, either one has gone to alarm status will shut down the AC contactor (cut the power).
If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer laptop (please select the "computerized tool" in the options bar) from us to avoid software installation problems.
