eQ RANGE INTEGRATED CONTROL SYSTEMS eQ RANGE INTEGRATED CONTROL SYSTEMS The Integrated control systems for the eQ Range is a complete, flexible and easy to use system. It offers a wide range of functionality to suit most applications and provides a high quality control solution. We can provide you with the Integrated control system for your FläktGroup eQ air handling unit. SIMPLICITY The eQ Control system has been developed and designed to be easy to configure, install and use. Therefore, an eQ air handling unit with a factory installed control system is a practical solution for consultants, installation engineers and end users. The integrated control equipment is supplied programmed, configured and tested such as running direction of fans and dampers, correct values of temperature sensors, alarms from heat exchangers etc. This reduces the risk of unwanted errors and saves you time on site when commissioning. eQ Master COMMUNICATION The eQ Control system supports communication via open standard protocols, which allows simple and cost-effective integration with building automation systems. Connection to other systems is carried out by the system integrator. Modbus RTU/TCP BACnet IP/MSTP HTTP EASY PROJECT DESIGN Using FläktGroup selection tool ACON, the project design of the eQ Control system is straightforward. ACON automatically selects the control equipment for the unit you have chosen. Valves and actuators are dimensioned for the relevant air heater and air cooler. Frequency converters are dimensioned for the relevant motor, drive system and fan. A simple yet effective solution that saves time. The eQ Control system is the perfect solution for both small installations with straightforward control functions, and also for large installations where data communication is required for optimal functionality.

eQ range integrated control systems LOCATION OF THE CONTROL UNIT Location of the controls as described in below pictures On the eQ Top units the control panel is located at the Top of the unit. On eQ Prime units the control panel is located at the energy recovery section. On eQ Master units Integrated control cabinet can be located on a fixed panel beside one of the fans, on either side or separated from the AHU and on top if it is a smaller one-storey unit. This you will configure in ACON. All incoming cables are connected to the control cabinet from below. Exception, incoming power cable...

eQ range integrated control systems CABLE ROUTING Cable routing in eQ Prime and eQ Top is internal. While for eQ Master modular units, the wiring is external in easy to open cable trunkings. The power supply cable must be fitted with a load main isolator, which can cut the power to the entire unit. The load main isolator is included as factory fitted standard on eQ Prime and eQ Master. For eQ Top it is available as a loose supplied accessory in ACON. The terminal block for incoming supply is rated for: eQ Top, max 35 mm2/80A (75A, AC23) eQ Prime, max 35 mm2/80A (75A, AC23) eQ Master, max 70...

eQ range integrated control systems DETAILED DESCRIPTION OF FUNCTIONS FAN SPEED CONTROL (eQ TOP eQ PRIME AND eQ MASTER , The performance of the fan is controlled by the speed of the fan. A variable speed drive connected to the motor performs this task and the eQ Control system, controls the motor drive. The following control methods are available for speed control. The sensors needed are included after the selection in ACON. CAV AND VAV SYSTEMS In CAV systems the fan speed control is used to maintain the flow irrespective of changes in pressure drop, arising from the clogging of filters for...

eQ range integrated control systems The following options are available for the temperature control eQ Control system. All necessary sensors are included. • Supply air temperature control Function: maintaining the temperature in the supply air duct at the setpoint. Setting: Set the supply air temperature • Extract air temperature control Function: maintaining the temperature in the extract air duct at the setpoint value, through the cascade control of the supply air temperature using minimum and maximum limits. Can be switched to control without cascade function. Setting: Set the extract...

eQ range integrated control systems A full range of two way and three-way valves in the sizes needed for the eQ and eQL range are available. Due to differences in tradition, climate and how water systems are configured there are several ways of doing a shunt unit. Whether you choose a site built or prefabricated shunt unit you need to know something about the water system to get all components at the right size. A correct Kvs value of your valve is in most cases mandatory for a smooth control function. Heating coil Cooling coil Combi Coil Temperature control Dehumidification control If you...
