Page 3: Product Overview
Product overview The Aga Er7 is an all-electric cooker that replaces the Aga Total Control it offers new enhanced features with everyday radiant heat and has independently controlled hotplates and ovens, features include: Capacitance touch-screen control panel with LED lighting. -
Page 4: Cooking Zones
Cooking zones Below is a picture showing the different cooking zones on the Aga eR7 100. All ovens and both hotplates are independently controllable using the control panel located behind the top left hand control door. Aga eR7 150 The Aga er7 150 has a hotcupboard attached to the parent Aga, the hotcupboard does not use the electronic controls that the eR7 utilises and is supplied either with a warming plate or a single zone induction hob on the top. -

TEK Vision opening screen with laptop connected When using the Tek Vision software ensure the cooker power on /off button is on. Below is a step by step guide to navigating the tek vision software. With the cookers PCB connected to your laptop using the appropriate connection key, double click the Tek Vision icon, Tek Vision will open and the below will be shown on your laptop screen , the default screen is the set up screen. -
Page 13: Tek Vision Diagnostics Screen With No Errors Present
TEK Vision diagnostics screen with no errors present Below is the temperature tab which shows the cooker working in real time and you will see that each zone shows the current temperatures recorded by the internal thermocouples and also in red it shows if any errors are currently present. -
Page 14: Tek Vision Diagnostics Screen With Errors Present
You will see above the fault count pop up box gives you the option to save the fault count to file. This must be saved and kept safe on every occasion a fault is found. This may be required as any fault diagnostic discussion with AGA. Page 14 of 34... - Page 15 To save the file, click the yes button and follow the instructions to save the file directly onto your laptop as shown below. Once the fault is cleared and with all zones on you should be able to see the below sceen on the laptop showing that all zones are turned on and the cooker is heating up normally and power sharing, it also gives information on,thermocouple temperatures,power being used and the user panel temperature.
