4. Scope of the ventilation controller The TROVIS 5177 Ventilation Controller is designed for controlling and monitoring air handling systems ranging from simple air heaters right up to complex ventilation and air conditioning systems that contain heating coils mixed air chambers cooling coils humidifiers and heat recovery units These mounting and operating instructions will enable you to operate the switches and keys of this controller as well as give an explanation of the electrical connection and mounting procedure Also the extensive possi bilities for configuration and parameterization are described Please note that changes in configuration and parameterization require specialized knowl edge on ventilation technology After the controller has been connected to the power supply it is basically ready for opera tion Since the controller functions according to time schedules make sure the time and date are set before start up Refer to page 22 onwards for step by step instructions on how to set the time and date The controller also saves information on con figuration and parameters in a memory thot can function for a long time without a power supply Only the time and date need to be reset after a power failure The controller contains default setting to oper ate the ventilation system from 07 00 to 22 00 hours If the two speed fans are acti vated the default setting for time of use between 10 00 and 15 00 hours
