<Removing the main controller from the hydrobox>
1. Open front panel of hydrobox. (See section 4.2.)
2. Remove the four screws from the metal back plate of main controller using a
screwdriver. (Figure 5.5.1)
3. Untwist wire clip and lift off the metal back plate.
4. Gently pull apart the clips holding the main controller in place. Be careful not
to use too much force as this may break the holding clips.
5. Lift out the main controller from the front panel of the hydrobox.
6. Separate the back and front plates using a flat head screwdriver as shown in
Figure 5.5.2.
7. Fix the 2 core cable from the FTC4 into the terminal. Ensure the wires make
good contact and are securely screwed into the terminal block. (Figure 5.5.3)
8. The inner core wires should not be visible from the outside of the back plate.
(Figure 5.5.3)
9. The sheathed cable should be pressed into the sunken channel so it is flush
with the back plate.
10. Once the connection cable is in place screw the back plate to the wall using
screws (field supply) suitable for use on the chosen wall. (Figure 5.5.4)
. Finally replace the front plate.
Note:
Wiring for main controller cable shall be (5cm or more) apart from power
source wiring so that it is not influenced by electrical noise from power
source wiring. (Do NOT insert main controller cable and power source wir-
ing in the same conduit.)
