Alternative cabling: e.g. external cabling: drill a small hole in
the bottom edge of the plastic cover for external cabling, for
the cable to go into the wall (see Figure 16, Page 7).

4. Screw the wires onto the terminals according to the wiring dia-
gram (see Figure 15, Page 6 pos 4). To simplify connec-
tion, the long terminal can be removed from the circuit board
when screwing on the wires. Pull the terminal straight out, do
not bend it to avoid damage (see Figure 15, Page 6 de-
tailed picture.
5. Slide on the control panel glass element from the bottom, and
hold in place (see Figure 15, Page 6 pos 5).
6. Tighten the lock screw in the bottom edge (see Figure 15,
Page 6 pos 6).
External ON/OFF switch (option)
The external ON/OFF switch can be positioned at any distance
from the control panel.
Connect the switch using low voltage wire (see
Figure 17,
Page
7 pos 4).

Additional ON/OFF switches must be connected in parallel. Sev-
eral individual units can be started or stopped via a single extern-
al switch.
NOTE! The control panel can also be connected to oth-
er appliances which give impulse or constant activation.
Terminal (-)21 is for indication - e.g. to show users status on the
control panel (built-in to Tylö external switches/impulse). The
function for this is:
• When the heater is unprogrammed: No diode lit. When
pressed, the heater will go to On and a steady diode light will
show on the external switch.
• When the heater is programmed but Off . The diode will flash
slowly. When pressed, the heater will start. The diode will
show a steady light.
• When the heater is in Standby -program: The diode will flash
rapidly. When pressed, the heater will switch from Standby
to On , and the diode will be on constantly. Indication must
be connected between (+)19 and (-)21, (3 V/DC max 0.3W
100mA).
Extra control panel (option)
Extra control panels (h2) can be connected as an option.
!
WARNING! When installing an extra control panel,
the heater must be disconnected from the mains.
After an extra panel has been connected, reconnect
to the mains and the system is ready for use.
The control panel can be connected in serial from terminal A or
B on the panel to A or B on the extra panel. Voltage can be con-
nected from te11 and -12 on the control panel to termin-
als +11 and -12 on the extra panel (see Figure 18, Page 7).
