7 Side 7 Systemair E28 integrated control system Topvex air handling units are built with a complete and fully integrated control system. Before shipment the unit has been assembled and passed a final functional test and inspection. Flyt Skjema Friskluft Avkast Avtrekk Tilluft Tilbehør til aggregat uten varmebatteri.

Mains power supply is to be connected directly in the main switchboard and cables for external components in the main switchboard or in terminal boxes at the gable of the unit. The unit should be permanently connected to the mains electric supply through a lockable safety switch. The safety switch is not mounted from the factory but delivered with the unit. Controller and hand terminal The controller is installed in the switchboard, and the programming and normal handling is carried out from a separate cable-connected (10m) hand terminal with display and buttons - the Systemair Control Panel - the SCP. The protection class of the hand terminal is IP 41. Schedules The regulator has individual schedules for start, stop and air flow rate for each week-day as well as schedules for holidays. The regulator has an automatic summer-winter-time change over. Outside normal operating hours free cooling is available according to settings. Variable Air Volume (VAV) control through constant pressure in ducts The air pressure of supply and extract air are controlled separately. The supply, extract, high and low air pressure in Pa is set separately on the hand terminal. The total air pressures are measured by pressure transducers in the supply air duct and in the extract air duct. A PI-regulator maintains the set point value by controlling the speed of the fans.

8 Side 8 Access rights - passwords There are 3 different log-on levels - Basic level (no password) - read-only access to all settings and parameters - Operator level (password) - read/write access to all settings and parameters, but no access right to the configuration of the system - Administrator level which has the highest authority (special password) - full read/write access to all settings and parameters (also configuration of the whole system) Alarms and safety functions If an alarm condition occurs, the Alarm LED on the hand terminal will flash. The LED will continue to flash as long as there are unacknowledged alarms. Alarms are logged in the alarm list. The list shows the type of alarm, date and time for the alarm and alarm class - A, B or C: - Alarm type A will stop the fans and close the dampers or switch the unit to a special mode according to the configuration - Alarm type B is only to inform the users about a failure, and the unit is still running as well as possible - Alarm type C - only to inform the user that the unit has been switched away from automatic running mode to manual control If water heater is used then for frost protection a temperature sensor is installed in a return circuit of the coil. The control signal to the mixing valve is kept at a level that secures that water return temperature at all times is held at a factory set minimum. This protection is also active when the unit is not running. This extended system offers the maximum of protection safety. If the water temperature is getting too low anyway the unit including fans is shut down. Flexible System A skilled service technician - on the site and on the demand from the user - will be able to adapt the regulation further to the requirements of the users; - The air flow can be adaptable to the CO2 concentration for CAV air flow regulation as well as for VAV air flow regulation - The temperature control mode can be changed. - In addition to the fixed schedule an external start signal for extended operation is available. - In addition or as an alternative to the fixed schedule an external start/stop input signal is available. - A large number of other alternative functions are optional. Modbus via RS 485, EXO line via TCP/IP (built-in WEB) The controller is prepared for communication via RS485 communication port to a MODBUS based BMS system (Building Management System). The controller can work as a stand-alone system without any support from other controllers.
