Attention! It should be noted that the maximum power of the lighting fixture controlled by the dimmer directly depends on its power factor, also cosφ - the ratio of active power to total power. In other words, this value determines the efficiency of the lamp, which part of the total power goes to perform useful work (in our case - lighting), and which part - to maintain the performance of the device itself.
It follows that when calculating the maximum power of the lighting fixtures that will be controlled by the dimmer, you must use the formula: Maximum power = 200W * cosφ
Adding a module to the central controller
To add the module module into the network, put the controller into teaching mode (see the manual of your controller) and apply power to the electrical network to which the device is connected. The device will be added automatically. If this does not happen automatically, press the system button located on the top cover of the unit three times briefly.
Attention! If there is a problem connecting the device to your network, you must go through the procedure of excluding it from the network and then repeat the power-on procedure.
To add removing (exclude) the module from the network, put the controller into exclusion mode (see the controller manual) and press the system button three times briefly. Please note, once the unit is excluded from the network, all the settings you made will be reset to the factory settings
You can also add/remove a device from the network with a switch which is connected to pin S1. If the switch is monostable (Parameter 15), then the addition/removal is done by triple pressing the switch for 2 seconds. If the switch is bistable (Parameter 15), the addition/removal takes place by successive combinations of switch on/off/on(1-0-1) or off/on(0-1-0) within 2 seconds.
Device control
The module can be controlled locally with a switch connected to it to contact S1 and S2. The switches can be either monostable (return or bell type) or bistable (standard switch with two fixed positions). To select the type of switch, set the corresponding value in Parameters 15 and 16.
Connecting the device
Attention! This device is powered by 230 Volt 50 Hz. Observe the safety rules during installation/dismantling of the device which are described in "DNAP 0.00-1.32-01". Before starting the installation, it is necessary to de-energize the electric network and the protection against accidental energizing of the network must be ensured. All electrical installation work must be carried out by a qualified electrician in accordance with current standards and regulations. If problems arise or if the installer cannot ensure safe operation during the installation, immediately de-energize the unit and the equipment connected to it.
Consider the fact that the module generates a small amount of heat during normal operation. Take measures to ensure normal heat dissipation. Do not install more than one module together in a confined space, and do not allow the module to be enclosed in insulating materials.
Choose how the СН-303 Dimmer is connected. If there is a neutral wire at the location of the module, use a circuit with a neutral wire (Fig.1). If there is no neutral wire, use the circuit without neutral wire (Fig.2). If the CH-303a module is connected, use the corresponding diagram (Fig. 3)

Parameters
CH-303 is a so-called "boxed product". This means that you just need to take it out of the box, install it according to the wiring diagram, add it to the network and the device is ready to work. But for your convenience you can fine-tune the device with a number of configuration parameters.
Automatic calibration is necessary when you first connect or when you change lamps connected to the dimmer. During the calibration process, the lamp will be 100% on and then off. The parameter will automatically return to the default value after the calibration process is successful.
-
- 0. (Default) Normal device operation
- 1. Calibration process.
Parameter in which the value for the minimum brightness is specified. Some lamps do not work correctly at the minimum brightness level, in this case you must experimentally select the minimum brightness level that corresponds to the normal operation of the device. Acceptable value is from 0 to 94.
0 (Default).
Parameter that specifies the value for the maximum brightness. The allowable value is from 6 to 99.
99 (Default).
The parameter specifies the time it takes for the light to go from minimum to maximum brightness and vice versa. If you select "0" in the parameter, the switching is instantaneous. Units used in the parameter: 0 - 120.
0 Instantly.
5 (Default).
1 120 - from 1 sec to 120 sec;.
After receiving the power on signal, the device will automatically turn off after a certain amount of time. If you select "0" in the parameter, the auto power off does not work. Units used in the parameter: 1 - 650 (1 = 1 second).
0 (Default).
The parameter allows you to set whether the module reacts to the broadcast commands "Enable All" and "Disable All".
0 (Default) Respond to "Enable All" command, Respond to "Disable All" command.
1 Ignore the "Turn All On" command, Ignore the "Turn All Off" command.
2 Ignore "Turn All On" command, Respond to "Turn All Off" command
3 Respond to the "Turn All On" command, Ignore the "Turn All Off" command.
If you want the device to be restored to its previous state after an electrical failure, select "Restore". If you want the device to be turned off after a power failure, select "Do not restore".
0(Default) Restore;
1 Do not restore. After applying power, the device will be in the "Off" state.
The device can operate with a non-dimmable load.
0. (Default) Dimmable load
1. Non-dimmable load
After receiving the switch-off signal the load will not switch off immediately, but after a certain time. In Parameter #14 you can select the cases in which the dimmer will ignore the Smart Delay. Acceptable value is 1-1800 (1 = 1 second);
0.(Default).
This option will allow you to configure the "Smart Hold" in more detail. The module can receive an on/off command from: - local switches; - controller (devices from the 1st group of connections); - other devices using communication; - of the sensor connected to the module on condition of combining the module with the sensor (Parameter No. 21) The module has the possibility of connecting one or two switches to it. The first switch can control the module directly, and up to ten devices can be connected to it (using the 2nd group of links). The second switch is used exclusively to control other devices (up to 10 devices) connected to it using the 3rd group of links. Monostable - for a return-type switch or for a button, each press switches the device to the opposite state. 0. (Default) Monostable - In this mode, each subsequent push of the button switches the device to the opposite state. Monostable switches support the dimmer control function. Pressing and holding the monostable button sends a start dimming command to the dimmer, releasing the button you can select the desired level of illumination; 1. Bistable - each subsequent switch change will change the load state (on/off) regardless of the initial key position; 2. Bistable, fixed position (Option 1) (contacts on the switch closed - load on, open - load off); Note that if the module receives a command from another device in the network, the load will change its state and must first be returned to the appropriate state to control the breaker. 3. Bistable, fixed position (Option 2). Similar to the previous one, but vice versa (contacts on the switch are closed - load is off, open - load is on). 4. Switch with middle position. A switch with 2 monostable switches, one connected to contact S1 and the other to contact S2. The switch that is connected to contact S1 - turns on and dims the lighting "up" - increases the brightness. The switch that is connected to the contact S2 - turns off and dims the lighting "down" - decreases the brightness. 0. (Default) Monostable - In this mode, each subsequent push of the button switches the device to the opposite state. Monostable switches support the dimmer control function. Pressing and holding the monostable button sends a start dimming command to the dimmer, releasing the button you can select the desired level of illumination; 1. Bistable - each subsequent switch change will change the load state (on/off) regardless of the initial key position; 2. Bistable, fixed position (Option 1) (contacts on the switch closed - load on, open - load off); Note that if the module receives a command from another device in the network, the load will change its state and must first be returned to the appropriate state to control the breaker. 3. Bistable, fixed position (Option 2). Similar to the previous one, but vice versa (contacts on the switch are closed - load is off, open - load is on). The parameter goes to the maximum light level after double pressing the switch connected to the contact S1. Sending such a command is only possible in monostable switch mode (Parameter #16 - value 0). 0. The function is disabled;
Operation parameters of pushbuttons/switches
Bistable - for conventional switches with two fixed On and Off positions.
1. (Default) The function is enabled.

Briefly about the C-Home system
All C-Home devices use a reliable and completely safe radio channel, on the basis of which the modules are combined with each other in a single network, which allows you to receive and transmit control signals to other devices in the network, using intermediate neighboring nodes.
The C-Home system has the ability to automatically reconstruct data transmission routes, depending on external factors, for example, if there is an obstacle between two neighboring devices, the signal will go through other nodes in the network in range.
C-Home is a two-way network. The devices can not only send control commands, but also wait for confirmation of their delivery and query the current status of the device. If the sending was not successful, the system tries to send the command another way.
The central element of the C-Home network is the Butler, which stores information about the network topology. It allows you to add and remove devices from the network and control all devices remotely. Not only C-Home company devices, but also more than 4,500 devices of various types and manufacturers can be connected to the Butler, which enables the implementation of any home automation tasks.
