After confirming that wiring is finished and verified that indoor units are ready to operate (see 4.) you can set up
the redundancy controller.
1.
Plug in DC power to the DC power connection and switch the unit ON. Take care that firstly the
external power supply has been connected to a socket, then switch the controller on. Never switch first
on, then insert the power supply, this may damage the controller. Similar for switching the controller
off: Firstly switch off by the on/off knob, then cut the power supply.
2.
Immediately after switching the controller to on, it will automatically switch the indoor units on/off for
just some Milliseconds and check if 2 or 3 indoor units (or groups) are connected. If not all connected
units are detected at that time (because maybe power supply missing on indoor or outdoor unit(s)), the
program will not run properly. In this case you can simply switch the controller off/on again to repeat
the automatic detection. Normal status is indicated by a green screen (Fig. 4-2):
Initial screen:
3.
Pressing the << MODE >> button shortly (less than 2 seconds) toggles between the 8 available screens.
Press it 2 times to get to the mode setting screen (All setting screens are in orange color). Here you can
set the mode "cool" or "heat" with the button <<0>>. Depending on the chosen mode alarms or cascade
control will be executed either with rising or descending temperature.
4.
Press again the << MODE >> button shortly (less than 2 seconds) to get to the limit temperature 1 setting
screen (Fig. 4-3). Upper line indicating "E 1". Here you can set the first limit temperature above which the
external alarm should be activated between 16 ... 30°C (cool) and 24 ... 50°C (heat) in 0,1 K steps.
Press << 0 >> for the digits after the comma, press << 1 >> for the ones and << 2 >> for the tenths. If
you exceed the limit, by default the next highest or lowest limit is chosen after confirmation.
Finish the temperature limit 1 setting by pressing shortly the << 1/2/SET >> button.
