General is an external electric boiler that provides extra heating output when the heat pump s output is not sufficient. EcoMiniEl consists of an immersion heater, junction box and is controlled from CTC EcoLogic Ext. has an 1" connection for the inlet and outlet. On there is a small venting valve to purge any air in the system. The tube is approved for max. 5 bar pressure. is available in following 2 variants: 1. 3x400V 2. 1x230V NB! can be used in CTC EcoLogic Ext, systems 4, 5, 6, 7, 8, 9 and 12. Technical data 1x230V 3x400V Output immersion heater (kw) 2, 4, 6 3, 6, 9 Contactor 1 (kw) 2,00 3,00 Contactor 2 (kw) 4,00 6,00 Maximum output (kw) 6 9 The immersion heater has two 1" connections with internal threads and a venting valve on the top of the tube. To get rid of possible air connect incoming water at the bottom and outgoing water at the junction box. 180 180 556 355 55 420 35 1/8" 1" Outgoing water Incoming water 96 5
!The immersion heater must be fitted vertically. Pipe installation The installation must be carried out in accordance with applicable standards, see BBR- 99 and the Heating and hot water directives 1993. The product must be connected to an expansion tank in open or closed systems. Do not forget to flush the radiator system before connection. Pipe connections on the product Make the connections as set out in the combination examples in the instruction. Also see the Dimension data for the dimensions and placement of connections. 6
Electrical installation Installation and reconnection in the heat pump must be done by a qualified electrician. Wiring must be done according to applicable provisions. EcoMiniEl is fully connected internally at the factory. It has an even phase load on all power steps. Electrical installation is done behind the front cover of the product. Loosen the screws on top (4), open and place the front to one side. The terminal blocks are located behind the cover of the distribution box. Connection cables are routed through the cable glands.!the immersion heater must be fitted vertically. Supply EcoMiniEl 3-phase must be connected to 400V 50~ and protective earth. EcoMiniEl 1-phase must be connected to 230V 50~ and protective earth Fuses sizes are stated under Technical data. Isolator switch The installation must be preceded by an isolator switch. Max thermostat If the EcoMiniEl has been stored in the extreme cold the max. thermostat may have tripped. Always check during installation that the max thermostat has not tripped. Electrical connections as illustrated below. 3x400V 1x230V 7

Settings in CTC EcoLogic Ext. Communication EcoMiniEl YES Max. number of steps 2 Activation of is done from the CTC EcoLogic menu: Installer->Settings->Communications->EcoMiniEl YES. The factory setting is No. The maximum number of steps permitted to be activated is selected from the menu: Installer->Settings->Communications->Max. number of steps 2. The factory setting is 2. The number of steps is adjustable between 0 and 3.

In order to test the function of set the menu: EcoMiniEl to YES in CTC EcoLogic Ext. The function test is performed from the menu: Installer->Service->Function test->ecominiel Off. Function Priority of the heat pump Operation with the heat pump is given priority above EcoMiniEl. If EcoMiniEl is in operation (the display shows C1, C2 or C3), and the compressor starts up, EcoMiniEl is switched off for 15 minutes to give the heat pump the opportunity to increase the temperature. If the heat pump has not succeded in increasing the temperature, EcoMiniEl is reactivated. Status. The status of EcoLogic Ext is displayed at the top of the Current operating info menu EcoMiniEl is activated in status: HP + auxiliary heat and in status auxiliary heat. NB! EcoLogic Ext operates EcoMiniEl in the conditions: Off, stage 1, stage 2 and stage 3. This means that EcoMiniEl is not always switched on, even if the status is showing HP + auxilary heat. Steps The output increases in steps every 10 minutes. The power is reduced in stages as the temperature approaches its stop value. Step 3 changes into step 2 at the stop temperature -2. Step 2 changes into step 1 at the stop temperature -1. Step 1 switches off at the stop temperature. Once EcoMiniEl has been switched off, step 1 can only be activated after 5 minutes. 9
Systems 4 and 7. Start temperature When the temperature is 5 degrees below its reference value. System 5. Start temperature When the upper tank temperature is 6 degrees (set diference + 1) below its reference value. Stop temperature stage When the supply temperature has reached its reference value. Stop temperature When the lower tank temperature is 3 degrees below its reference value (if the compressor is not running). System 6. Start temperature When the upper tank temperature is 1 degree below its reference value. Stop temperature When the lower tank temperature is 2 degrees (5 if the compressor is not running) above its reference value. Systems 8, 9 and 12. Start temperature When the upper tank temperature is 1 degree below its reference value. Stop temperature When the lower tank temperature is 3 degrees below its reference value (if the compressor is not running when the returntemperature reaches its reference value). Startup Once EcoLogic Ext has started up, step 3 in EcoMiniEl is blocked for the first 2 hours. C. 2 Display on. The digits to the right indicate the number of steps that are activated. The number of activated steps varies between 0 and the maximum number of steps selected in EcoLogic, menu Max. number of steps. The display always shows a C on the left of the display. 10
Resetting the max. thermostat The max. thermostat is reset by pressing the red button on the junction box. Always check during installation that the max thermostat has not tripped. See the figure below how to reset the max. thermostat. Reset button 11
