7. Screw the mounting plate tightly on the conduit box using a screwdriver,
making sure the mounting plate is placed correctly (the part with the upward
arrow placed on the top).
8. Connect the labeled wires to the terminals following the thermostat terminal
designations. Use a screwdriver to tighten down the screws to secure the
inserted wires.
NOTICE! There are four pairs of L and N terminals on the power unit.
However, you can combine any L with any N terminal.
9. Screw the power unit on the mounting plate tightly.
10. Attach the front module horizontally. Ensure that each side of the front module
aligns with the power unit and press the corners in the order illustrated below:
Top (1); bottom (2) until each corner clicks in place. Note: You must discharge
static electricity from your body before mounting the front module. For example,
touching the wall can help discharge static electricity.
11. Switch the power back on to your heating system and thermostat by using your
home's breaker box.
See the Mounting instructions
●
Comply with local regulations to wire, fuse and earth the thermostat. Connect
the conduit box to earth (safety ground).
●
Adapt the line diameters as per local regulations to the rated value of the
installed overcurrent protection device.
●
The line voltage cables and signal cables must be arranged separately.
●
X1, M and X2 wires operate at SELV (Safety Extra Low Voltage) level. Do not
insert cables with AC 230 V mains voltage into terminals X1, M and X2 and
vice versa.
●
Isolate the cables of inputs X1, M and X2 from AC 230 V mains voltage.
●
The AC 230 V mains supply line must have an external circuit breaker with a
rated current of no more than 10 A.
●
Screw down all terminals regardless of whether cables are connected or not.
●
Properly size the cables to the thermostat.
●
Screw down the cables tightly and make sure no bare copper is exposed.
●
Disconnect from power supply before removing the front module and the
mounting plate.
●
Use a cable lug to avoid touching of mains and neutral wires, if the power cable
is made of RVS wires.
