10.0 Electrical 10.1 Making The Electrical Connections This appliance shall be connected to a suitably protected electrical supply i.e., 16A - see section 7.7. NOTE: Ensure all cables are secured using the cable clamps provided. When accessing the appliance controls area, take care not to let the control box drop down in an uncontrolled manner as this may cause damage. 1. To gain access to the controls tray / electrical wiring area, remove the outercase by lifting off the plastic fascia that is held on by two magnets. Undo the two screws holding the outercase, pull the bottom edge forward, lift and disengage from the top of the appliance (Fig. 40). 2. Slacken the four screws from the bottom cover and remove the cover (Fig. 40). 3. Remove the two screws holding the control tray. Pull the front of the control tray forward and lower it carefully (Fig. 41). DO NOT allow the tray to fall in an uncontrolled manner. 4. Ensure all cables are secured using the cable clamps provided. Fig. 40 Plastic Fascia Bottom Cover 5. Ensure that the lengths of the live and neutral conductors are shorter that the earth conductor, so that if the cable slips in its anchorage the current carrying conductors become taut before the earth conductor. 10.2 System installation options. 1. There are two installation options available, Intelligent and Retro. Y-plan, S-plan, W-plan and S-Plan with a second heating circuit are all available both with Intelligent and Retro installations. IMPORTANT: Before running the appliance ensure parameter 5700 has been set according to the type of system installed. See sections 10.4 to 10.11 for system types and section 11.3.k for the change procedure. Control Tray Control Cover Fig. 41 A) An Intelligent system operates the Ecogen with room sensors, an optional extra outdoor sensor (an outdoor sensor can only be installed in conjunction with a room sensor to enable weather compensation), a DHW tank sensor or DHW tank thermostat and will give the highest overall efficiency with increased electrical power generation and is therefore the recommended way to install the appliance. The Removable THINK Controller must be used as a Programmable Room Sensor for all intelligent installation. B) Retro installations operate the Ecogen with a new or existing external system wiring centre. This means that the installer has the option to retain an existing room thermostat, DHW thermostat and programmer. An outdoor sensor for weather compensation cannot be used in this case. The THINK Controller must remain on the appliance (See Section 10.11). © Baxi Heating UK Ltd 2012 37
