For the installer
24.2 First start
Switch on the power using the safety switch. The display will come on and
the operating lamp will start to light up. Factory-set values will apply, so for
instance, the connected heat pumps’ compressors are blocked. The first
time the EcoZenith is started up or if it is restarted within 24 hours after start-
up, items 1-3 are displayed.
1. Select language – English – and confirm with OK.
2. Specify the maximum electric heater power. Choose between 0.0 and
9.0 kW in steps of 0.3 kW.
3. Confirm that the system is filled with water with the OK button.
4. Define system. This menu is shown automatically on first start. It also
occurs under: Installer/Define system See the chapter: Define system
Menu.
– The EcoZenith senses whether primary flow sensors 1 and 2 and
room sensors 1 and 2 are connected and if so automatically defines
radiator systems 1 and 2 “Yes” with the associated room sensor “Yes”.
– Scroll further down in the menu and select the connected systems
with “Yes”. The immersion heaters are factory set to “Yes”.
– For heat pump operation, the pumps in question are defined 1, 2 and
3 by selecting “Yes”. For the relevant heat pump, the type of heat
pump must then be selected, EcoPart or EcoAir, followed finally by
selection of relay-controlled or speed-controlled (PWM) charge pump.
5. Settings.
– Set the inclination and adjustment for each defined radiator system in
the menu: Installer/Settings/Heating circuit 1, 2, 3. See the Radiator
System Menu chapter.
– Allow the compressor in menu Installer/Settings/Heat pump 1, 2, 3
see section Menu Heat pumps.
– Set the size of the main fuse, and check that the rated power of the
immersion heater(s) matches the capacity of the fuse panel.
6. Current operation information.
– Check whether heat is needed in the upper and lower tank Heat
is needed when the temperature in the upper or lower tank is 5°C
below the setpoint in brackets. When this occurs, start-up of the
compressor should be delayed 10 minutes. Information on this is
available in the main menu. Return to the main menu to check.
7. The EcoZenith is now up and running and the product is working using
it factory settings. See the chapter “Detail Description Menus” for other
settings.
