1. As energy export increases and decreases the E R S is continually reacting to this change by varying the amount of power supplied to the heating load This is indicated by the Power Bar which moves from left to right according to how much power the E R S is diverting The display is updated every 2 seconds As the Power Bar steps increase the live export reading on the top line decreases depicting the movement of recovered energy from the grid to the heating load Each step represents 5 of the total heating load e g 5 of 3kw load 150w steps When E R S is recovering energy during the day it will always leave a small amount of export to ensure inadvertent import does not occur During the night E R S will display the live imported energy of the building in kW The power bar will be empty indicating that E R S is not powering the heating load CONTROL ELEMENTS Boost OFF Button Home Screen Boost ON Button Home Screen Menu Button Home Screen Enter Menu Start Manual Boost Stop Manual Boost Menu Screen Menu Screen Menu Screen Exit Menu Up change setting Down change setting Enter Backlight Button Home Screen backlight OFF Turn on backlight Home Screen backlight ON Display kWh Meter Navigation Overview Button Functions when on the Home Screen Use the Enter Button to scroll through the menu options and the arrows to change the option settings Enter Backlight pu2.
