- Hardware installations
Note that if you intend to connect high-voltage devices(for ex. 220-230 Volts) directly to the Webswitch, depending on your country’s regulations and laws, you might have to consult a authorized person(electrician) for the installation.
Installation of temperature sensors
If you want to use Webswitch 1216H for measuring temperatures and/or controlling relays based on temperature you have to connect at least one temperature sensor to the Webswitch. The supported models of sensor are Maxim DS18B20 and DS18S20(from firmware version 2.20). The supported range when measuring temperature is -55 to +125 C degrees. The supported range when controlling temperature is 5 to 99 C degrees.
The temperature sensors look like small transistors in TO92 cases. They should be connected according to the picture below. Data sheets for the DS18B20 is available here=>. The cables to the temperature sensors should be more than 10 cm to avoid heat from the PCB to be transferred to the sensors via the ground wire.
Installation of the radio module
The radio module is used to send and receive codes which control remote switches, for ex. “Nexa” and compatible brands.
The radio module looks like this:
The module is installed inside the Webswitch at this location:
Make sure to turn off every connected high voltage device before the installation!
When installed it should look like this:
Note! Make sure not to misalign the module’s pins as that might damage the module and/or the Webswitch!
Also note that the radio module only can be used in combination with the the “extended” version of the Webswitch!
Using the digital inputs
There are two digital inputs which can be used in the Auto Control Programs. For both of them the inactive mode is “High” and the active mode is “Low”. Inactive mode is when the screw terminal connection “IN-1″/ “IN-2″ is left unconnected to “0V”. Active mode is achieved by connecting them to the the “0V” terminal which is located between them. No voltage should therefore be applied to them.
