Funct ion DIP sw it ch:
•
SW1
The dialing code mainly controls and selects the
type of unit. It is suggested to adjust under the
guidance of the engineering sta .
SW1-1: Switch communication mode function,
(ON: 24V wire controller; OFF: non-24V wire
controller, default)
SW1-2: This dial code can be used to set whether
to stop the fan when the cold air is released, OFF
stops the fan, ON does not stop the fan, default
OFF
SW1-3: Select single cold and heat pump functions.
ON: single cooling; OFF: heating and cooling,
default
SW1-4: The dialing function is to select indoor and
outdoor unit or indoor unit. The default OFF means
the indoor and outdoor unit, at this time you need
to connect the outdoor unit equipped with the
AHU set. When the user uses the temperature
control to control the indoor and outdoor unit,
they need to switch the dialing code to ON, which
means the independent indoor unit; at this time,
the indoor unit module does not communicate
with the outdoor unit, and does not process the
information of the outdoor unit. The wire controller
cannot be used, it needs to be connected to a
24V thermostat.
•
SW2
This dial code mainly controls the opening
form of the electric auxiliary heat.
SW2-1: This dial code can control the temperature
di erence when the electric heating is turned on.
OFF: 2°C, default; ON: 1°C, 3-level temperature
setting, consistent with user thermostat setting.
Note: When E/AUX controls electric heating,
there is no temperature di erence, and it starts
directly.

SW2-2, SW2-3: This two-digit dialing code can
control the delayed start of electrically-assisted
heat.
When the temperature di erence is too large,
the delayed start and the delayed start time can
be selected.
1-bit dialing, ON 2.5°C,
SW2-2
OFF without delay
1 bit dialing, OFF 15 minutes,
ON 30 minutes, 15 minutes by
SW2-3
default, delayed opening time
SW2-4: This dial code controls the allowable
opening temperature of electric heating or
compressor, OFF allows the opening temperature
of electric heating (using the set temperature of
S3 as the upper limit temperature of electric
heating), and ON the allowable opening
temperature of the compressor (using S3 as the
upper limit temperature of electric heating). The
lower limit temperature at which the compressor
can allow operation.)
•
S3
Ambient temperature controlled by electric
heating or compressor, 0 means no temperature
protection is turned on, 1-F is -20-8°C, and each
scale represents 2°.
SW3-1
This dialing code can set the continuous operation
time of increasing the set temperature by 0.5°C~3°C
before reaching the temperature. The default is
OFF 1.5h, ON 30min.
SW3-2
This dialing code can set Y/Y2 signal setting
temperature adjustment deviation, ON: 1°C;
OFF: 2 ° C.
SW3-3
This dialing code can set W2 signal setting
temperature adjustment deviation, ON: 2°C;
OFF: 3 ° C.
