Installation instructions for controls EB-A, EB-B and EB-C for convectors www.minib.com Introductory information Minib controls are supplied from a standard 230V/50Hz supply network. To ensure electrical safety SELV low voltage at 12V AC is used to supply the convectors via an isolating transformer. TT100, TT240 and TT300 are available according to the power requirement. All electrical installation work must be undertaken by a qualified electrician. The DC motors within the convectors are fed by the electronic board EB; this regulates the heat output by controlling the fan speed. The electronic board contains a microprocessor which is programmed for all three types of control EB-A, EB-B and EB-C. No adjustments need to be made between the various control options as the controller automatically responds to the character of the control signal and selects the appropriate type of regulation (note for control type EB-A a jumper must be fitted to the electronic board). The power supply from the transformer must be connected to terminals marked 12V AC in the convector. If a thermal switch is used (supplied with all convectors) then the power supply is connected to terminals 12V AC and TK (see wiring diagram). The thermal switch is open when the water temperature is less than 35°C and the fans are stopped. For convectors also designed for cooling the contact closes when the cooling water temperature drops below 15°C. The power supply should be connected directly to the 12V AC terminals in order to test the functionality of the unit and controls. If the thermal switch is to be used then the wire should then be connected from terminal 12V DC to terminal TK (see control wiring diagrams). The power supply to individual convectors can be made with cables with the relevant cross section and branching at each convector. Parallel (Y) connections can also be made between the transformer and the convectors and is more suitable for systems with several concevtors. In each case the distance between the power supply (transformer) and the convector should not exceed 15m. Branching can be done in an electrical box in the wall or via the terminals directly under the cover of the convector. CONTROL EB-A Characteristic EB-A is the simplest form of control and uses a potentiometer to continuously regulate the fan speed or switch the fans off. The control is intended for regular areas which are occupied and the control can be adjusted by the occupants. Output is varied by rotating the wall mounted hand potentiometer. a/ The potentiometer in the frame ABB Tango b/ The rotary thermostat in the frame ABB Tango.

Description of function: In order to prepare the convectors for continuous speed control it is necessary to connect the jumper on the electronic board. Loosen the central screw which holds the board in place then push the board gently away from the convector so that there is access for fitting the jumper (do not disconnect any cable). Having fitted the jumper the board is replaced with the screw into the original position. Note. The power must be disconnected while fitting the jumper. The potentiometer is connected by three wires to the closest convector at the terminals marked 12V DC, 0V DC and Ur. Any multicore cable can be used that has multicoloured wires, for example 4 core communication cable with 4x0.19mm2 conductors and the blue wire in 0V, the red wire in 12V and the third wire of another colour in Ur, the control voltage. If automatic control of set temperature is required then a thermostat can be wired into the potentiometer which switches of the fan when the set temperature is reached. If a thermostat is used then the jumper wire between terminals A and B in the potentiometer must be removed and the terminals reconnected to the switching contacts of the thermostat (same wire specification as between potentiometer and convector). One potentiometer can control up to 10 convectors. CONTROL EB-B Characteristics Control EB-B automatically sets the fan speed based on the evaluation of the rate of switching of the thermostat. The controller reacts to the opening and closing of the thermostat contacts to optimise the convector output and provide excellent dynamic control of the space temperature and minimise the noise levels of the fans.

Description of function: The thermostat compares the required space temperature with the actual space temperature. When the space temperature is above the required temperature the thermostat contacts are open and when it falls below the set temperature then the contacts close. The is an hysteresis of around 1°C between the opening and closing temperatures which prevents rapid opening and closing of the contacts and inefficient control. This ensures that a minimum switching period of around 1 minute is maintained and is particularly useful if the boiler is also controlled by thermostat. The 12V DC signal from the thermostat is applied to terminal Ur on the electronic board in the convector. The electronic board evaluates the switching period between on and off and sets the fan speed accordingly. Any two core cable can be used for interconnection or the thermostat and the electronic board; communication cable or power cable. CONTROL EB-C Characteristic Control EB-C allows convectors to be operated in either automatic or manual mode. The control is design for use with thermostat TH0482 which is adapted for a 12V DC supply taken from the electronic board within the convector. In automatic mode control is similar to EB-B where the fan speed is set by the controller based upon the regularity of the opening and closing of the thermostat switching contacts. The highest available fan speed is set by the switch on the thermostat. In manual mode the speed is set at low, medium or high and overrides the thermostat. Description of function: In automatic mode control EB-C compares the required space temperature with the actual space temperature. When the space temperature is above the required temperature the thermostat contacts are open and when it falls below the set temperature then the contacts close. The is an hysteresis of around 1°C between the opening and closing temperatures which prevents rapid opening and closing of the contacts and inefficient control. This ensures that a minimum switching period of around 1 minute is maintained and is particularly useful if the boiler is also controlled by thermostat. A signal from the thermostat at a voltage level corresponding to low, medium or high speed as set on the thermostat is applied to terminal Ur on the electronic board in the convector. The electronic board evaluates the periods of on/off switching and the voltage level to automatically set the fan speed. In manual mode a voltage is applied from the thermostat to terminal Ur in the electronic board and the corresponding fan speed (low, medium, high) is set. The potentiometer is connected by three wires to the closest convector at the terminals marked 12V DC, 0V DC and Ur. Any multicore cable can be used that has multicoloured wires, for example 4 core communication cable with 4x0.19mm2 conductors and the blue wire in 0V, the red wire in 12V and the third wire of another colour in Ur, the control voltage.

Installation of the heating system with convectors MINIB begins by placing of convectors to selected positions - see the installation procedure convectors and by their connection to the heating system. 2. The isolating transformer and thermostat shall be placed to the selected place. 3. Apply the necessary connecting cables – see the wiring diagram. Branching of cables can be made either in boxes in the wall or directly on the terminal board in convectors. The terminal board for connection of power and control wires is placed on either on the electronic block or on the main body of the convector. The wires must be connected to the proper positions on the terminal board. Wrong connection may lead to the destruction of the electronic block and will not be accepted as the reason for complaint. Therefore, pay a considerable attention to the correct connection. The picture shows the junction box of the convector, including the connection of the temperature switch. 4. The temperature switch shall be connected according to the customer`s requirement. 5. Perform the electrical connection of all control components and convectors according to the selected wiring diagram. Description of activation 1. If water in convectors is not hot enough and the thermal contact is used, it is possible to test the function of convectors after switching power supply wire from the terminal TK to the terminal 12V AC. After the test, the wire shall be returned back to the terminal TK. 2. The activation of the control shall be performed in the way that you switch on the circuit breaker in the main switchboard after the connection check. The heating system will be put into operation. 3. You will set the heating mode on the thermostat and select temperature that is higher than the actual temperature in the room. Depending on the thermostat type, the thermostat must switch on at the latest approx. in 1 minute. (This delay applies only to electronic programmable thermostats, which prevents to fast repeated closing and opening of contacts and which could lead to damage of some elements of heating systems.) 4. After switching the thermostat on all fans must start running in all convectors. Speed of all fans will become stable on the same (set) speed within 1 minute. 5. Then set the temperature on the thermostat safely lower than the temperature in the room. The thermostat must switch off approx. within 1 minute at the latest. Fans at controls EB-B and EB-C will further run but their speed will be gradually decreasing. All fans must stop maximally after 20 minutes. At the control EB-A, it is possible to test the speed setting, eventually to stop fans by turning the knob of the potentiometer. When setting the speed, you must calculate with a certain time delay until stabilization of the corresponding speed. When zero speed is set, the fans will stop immediately. www.minib.com
