Johnson Controls C450CCN-4 Control Module 2 SPDT Relay Output

The Johnson Controls C450CCN-4 Control Module is an easy-to-use product that is designed to help you manage your HVAC system’s temperature. It serves as a single zone to enable you to achieve and maintain the comfort that you desire. It comes equipped with a display that constantly displays the current temperature values. The four-button touchpad allows you to set the temperature range you want conveniently; this is your setpoint. The module then utilizes its intelligence to regulate your HVAC equipment such as a furnace or an air conditioner with the help of its two SPDT relay outputs. These relays work like switches that either engage or disengage the connected equipment to get to your desired temperature.
