contact, disconnects power supply to the main board of the
unit, leaving it inoperative.
Shoud the phase sequence be correct and the centrifugal
fan of the indoor unit (BCVI) rotates in the wrong direction,
interchange two phases at the bottom of the fan contactor.
Dryer filter
Coupled to the cooling circuit to protect the refrigerant against
humidity.
Casing
Made of zinc-aluminium plated steel sheeting, primed and
enamelled in epoxy power for outdoor installation.
Complementary heaters
Of the open-air wire type for fast heat dissipation, avoiding
temperature inertia that could affect components.
Operating diagram
Thermostat
The SCOH/SICH-070 to 300 units include, as standard equip-
ment, the electromechanical DPC-1 thermostat.
To connect the thermostat to the board, 10x0.22mm
2
screened communication cable should be used.
Ambient thermostat DPC-1
Programmable digital thermostat with communication
This thermostat was designed to give close control of the
ambient temperature and graphic information regarding
the mode it is currently operating in. This control unit, in
accordance with the differential between the programmed
temperature and the ambient temperature, responds varying
the on/off cycles.
The liquid crystal display (LCD) normally indicates the ambi-
ent temperature, operating mode and whether the system is
in heat or cool.
