NOTE: The new style IQ 2020 control board/motherboard (part number 77087) does not have thermistor ports on the side of the box. The control thermistor and hi-limit thermistor connect directly onto the IQ 2020 motherboard. If your current IQ 2020 control box has thermistor ports, then you will need one Control Thermistor 39530 and one Hi Limit Thermistor 39525 in addition to this product.
