Description
The Johnson Controls TM-9100-8902 Serrated Knob Kit Individual is not a temperature sensor. It is designed to work with Johnson Controls TM-9100 series Room Command Modules that are applied to control different HVAC operations. The replacement knob is an individual one and has a serrated shape for better grasping even with gloves. Its function is to replace a worn or damaged knob on the Room Command Module. Thus, the replacement of a faulty knob with the TM-9100-8902 returns the regulation of the HVAC system to the consumers. They can easily turn the knob to adjust things such as temperature or fan speed so that people can continue to feel comfortable in the building.
