The ON/OFF switch of the ThermoControl switches the appliance ON and OFF. Note that in the OFF position the appliance remains electrically live, in order for the continuous pump to stay running.
After switching on, the text INTERNAL CHECK appears on the display for about 10 seconds. The main menu then appears (see chapter ’8 Main menu’). If no selection is made in the main menu, the appliance automatically switches to OFF mode. See paragraph ’6.2 Operating modes’.
nRemark
To electrically disconnect the appliance, you must use the main switch between the appliance and the mains power supply.
The use of these buttons is explained with the help of Figure 5.4. This figure shows the main menu. See also chapter’8 Main menu’.
The navigation buttons are:
•Buttons UP Hand DOWN L;
•Enter: E;
•Reset button: R
The arrows ^ and È indicate that you can scroll up and/or down. Use buttons H and Lto scroll.
The cursor » points to the option to be activated. In the display as shown in Figure 5.4 you can scroll through the main menu.
The main menu consists of: OFF, ON, WEEK PROGRAM, EXTRA PERIOD and SETTINGS. The options EXTRA PERIOD and SETTINGS only become visible after scrolling downwards.
The selected option is confirmed using E.
With the Rbutton, you go back one page in a menu, and all options selected in the current menu are lost.
nRemark
The Rbutton is also used to reset the appliance following an error.
The PC connection is exclusively intended for technicians from A.O. Smith who can read the status and history of the appliance. These details can be important for troubleshooting and/or responding to complaints.
