3 DIP switch instruction

Two DIP switches S1 and S2 are installed on the dry contact gateway. Before
energization, please set to proper position according to requirement. Once
energization is finished, please do not dial any DIP switch. As for the function
definition for DIP switch S1 and S2, please refer to table 3.1 and table 3.2.

4 Functions

4.1 Shield general terminals

Once the first bit of DIP switch S1 is set to Digital position (General terminals
control disable), the unit will shield the general terminals (wired controller, remote
controller, APP and light board), and high-end terminals (central controller,
long-distance monitor, keycard control) and dry contact gateway can still control the
unit. When the first bit of DIP switch S1 is set to ON position (General terminals
control enable), all the terminals can control the unit.

4.2 Input function

Dry contact gateway is compatible with level input method and impulse input
method, which can be selected by the second bit of DIP switch S1. Each input
function can be set as enable or disable through the corresponding bit of DIP switch
S2. When it is set as disable, the unit won’t execute corresponding input command.
The following descriptions of input functions are supposed as the input functions are
enabled.

4.2.1 Level input

Under level input method, the input command is decided by the
Connected/Disconnected of the dry contact. Each time when the status of dry contact
is changed, input commands of all the dry contacts will be re-executed. The

5

relationship between dry contact status and the input command are shown as the
table 4.1.

4.2.2 Impulse input

Under impulse input method, for each detection of dry contact from disconnected
to connected (connected time should be more than 500ms), it is deemed as valid
impulse input. When valid impulse input is detected, dry contact gateway updates
corresponding input commands. The detail commands are shown as Table 4.2. For
each detection of valid impulse input, commands of all the dry contacts will be
re-executed. When dry contact gateway is energized, it needs about 6 seconds to
acquire operating status of unit, during such period, all the inputs are invalid.

4.3 Output function

The dry contact gateway will output corresponding function and status by
controlling the connected/disconnected of the dry contact. User can connect power
cord with load to the output terminal to turn corresponding load ON/OFF via dry
contact gateway. Definition of output contacts are shown in Table 4.3.

5.2 Installation requirement

(1) Do not install the product at wet place or the place where there’s splashing

water.

(2) Do not install the product at the place where is closing to the

high-temperature object or the position with direct sunshine.

(3) This product is suggested to be installed at indoors. The suggested

working temperature range for installation is 0～50℃.

(4) Before installation, please cut off the power for the strong wire embedded

in the installation hole on the wall. Ho-line work is not allowed during the
complete installation process.

(5) Please pay attention to below notices for wiring to avoid abnormal

phenomenon due to electromagnetic interference.
1） Make sure the communication wire connects to the correct interface.

Otherwise, there will be communication error.

2） The communication wire of dry contact gateway (4-core wire) should

be separated from other power cord and the minimum distance
should be more than 20cm. Otherwise, there will be communication
error.

5.3 Wire specification

It is recommended to use the connecting wire with cross sectional area of

10

0.75mm² for input and output of dry contact gateway.

5.4 Wiring instruction

5.4.1 Communication and power cord connection

Connect one end of wiring (4-core wire) to the COM1 needle stand of dry
contact gateway and then connect the other end to the 4-core COM1 or COM2
needle stand of the indoor unit.

5.4.2 Connection of input dry contact

Connect two terminals of each group of input dry contact to the both ends of
switch respectively. Single control switch is suggested for the level input method, and
touch switch is recommended for impulse input method.

5.4.3 Connection of output dry contact

Connect the two terminals of each group output to the load respectively. The

requirement for the allowable connected load:

(1) Weak current：12~24VDC(100mA～500mA).

(2) Strong current：200~240VAC(100mA～3A).

5.4.4 Installation procedure

(1) Remove the screws used for fixing the front cover; Open the front cover of

dry contact gateway.

(2) Check whether the screws used for fixing the main board is loose. If yes,

please tighten the screws to fix the main board.

(3) Attach the bottom case of dry contact gateway at the installation position

(such as the wall) and then use screws to fix the base case and the
installation hole on the wall together.

12

(4) Set the DIP switch S1 and S2 to the corresponding position.

(5) Put the wire through the rubber ring and make sure the basic insulation

layer and the protective jacket of the wire can put through the rubber ring
and wire clamp.

(6) Connect the wire to corresponding terminals, and screw up the screw in

the contact to make sure that it will not loose.

(7) Use wire clamp to press the wire, and screw up to fix the screws of wire

clamp. If the wires for connecting are less than 3 sets, please use white
wire clamp, otherwise use black wire clamp.

(8) Close the front cover of dry contact gateway and then tighten the screws of

the front cover.
