11.4 Outside unit connection
Besides the power mentioned in previous paragraphe it
is necessary to provide to the outside unit the following
connections too:
• Connect the temperature probes B2 and B3 (B3 only in
case of domestic management) (see terminal teble at
paragraphe 12.2)
Probes supplied by the parent company (in case of extension
cord use the 1,5 mmQ multipolar cable shielded following
the shortest route and far from the power cable. Spend
particular attention on the connections since the possible
parasitic resistances affect the reading).
• If there is a boiler/additional resistance, connect it to
the relay in the board. The relay has a common contact
exchanging NA-NC.
• If there is a flowmeter (KITA Energy) consult the electrical
schemes 13.5, 13.6, 13.7 (B5 = clamp 37)
11.5 Connection between indoor and
outdoor unit
• Use a 4 wires cable 1,5 mmq shielded for the connection
of:
- Flow switch
- Return proble B4
- Flow probe B7
- GND commmon
the cable carries low voltage control signals: look for a
route far from possible sources of trouble, don’t make
joints along the way.
• Use a 2 wires section 1,5 mmq multipolar cable to connect
the circulator. In case of circulator management with
modulation PWM previde another cable to connect to the
special clamp.
11.6 Connection of the remote panel
The remote panel cable of the split unit is supplied already
installed on the cover of the indoor unit. A cable of 3 m is
supplied by the parent company and in case of it is necessary to
make an extension cord use an ethernet 6 wires cable which can
be layed with the probe cable with the same precautions.
WARNINGS!
A ferrite toroid is suggested to be used to protect the remote
panel from possible external trobles.
