Version 4.0:

Older versions:

Parameter description:

Function type select how you want to use the Webswitch. The switch above is set to be used with manual relay control with the possibility to read the temperature sensors. There are also modes for Heating/Cooling control, Fan control and Antenna Selection.

ICOM CI-V Addr.(hex) is used with Antenna Selection in ICOM and R&S XK2000 mode.

Cycle (min) set is for Heating/Cooling control how long the total control cycle is, in slow systems like a house you may use 15-20 min, in a small cupboard shorter may times fits better. If cycle time is set to 0 the cycle time is set to 20 s. If you just use the WEB-Switch just for reading temperatures set cycle time to 0 to get shortest possible update time.

The Heating/Cooling control mode uses relay 1 for heating control and relay 2 for cooling control. The wanted temperatures are entered here. The temperature sensor used is the 1-wire device saved on position 1 in the list. Relay 1 is activated when the temperature is lower than the wanted temperature and inactivated when the temperature is higher than the wanted. Relay 2 is activated when the temperature is higher than the wanted temperature and inactivated when the temperature is lower than the wanted. A hysteresis is used to avoid relay toggling around the wanted temperature.

Fan control for firmware versions older than 4.0:

The Fan control mode uses relay 1 for controlling a fan which can be used to move warmer air from a place to another place with a lower temperature. It uses two temperature sensors, number 1 and 2 in the list. Temperature sensor number 1 is used for the place which is to get warmer air from the other place using sensor 2. The wanted temperature is entered here.(at “Set Temp Relay 1 (5-99C):”).

Relay 1 will be activated if:
The temperature at sensor 2 is higher than at sensor 1 and the temperature at sensor 1 is lower than entered. There is also a hysteresis used in order to not toggle the relay with too short intervals when the temperature is near the aimed temperature.

Difference control(Fan/Heating) for firmware versions 4.0 and newer:

The Fan control mode uses relay 1 for controlling a fan which can be used to move warmer air from a place to another place with a lower temperature or for controlling a heating source that keeps the inside temperature a selectable number of degrees higher than the outside temperature. It uses two temperature sensors, number 1 and 2 in the list. For fan control temperature sensor number 1 is used for the place which is to get warmer air from the other place using sensor 2. The wanted temperature is entered here.(at “Set Temp Relay 1 (5-99C):”). In Fan control mode Set Temp Relay 2 must be 0(zero). 

For Heating control mode sensor 1 is placed inside and sensor 2 placed outside and both Set Temp Relay 1 and Set Temp Relay 2 are used.

Relay 1 will be activated if:
The temperature at sensor 2(outside) is higher than at sensor 1(inside) minus the setting Set Temp Relay 2 and the temperature at sensor 1(inside) is lower than entered.  Setting Set Temp Relay 2 to 0(zero) makes it work like previous firmware versions = Fan control, while values greater than 0(zero) will make it possible to for ex. keep the indoor temperature Set Temp Relay 2 degrees higher than the outside temperature. There is also a hysteresis used in order to not toggle the relay with too short intervals when the temperature is near the aimed temperature.

Enabling Relay extension master makes it possible to connect two Webswitches via the 1-wire interface(BUS-A only) and control up to a total of 10 relays(5 per Webswitch) manually, based on frequency bands for selecting antennas, or by Auto Control Programs/Car Warm Up. Note! BUS-A will then be exclusively in use for this purpose and so it can’t be used for other 1-wire devices like temperature sensors. Also note that you should only enable Relay extension master in one of the Webswitches, the one which will be used as master(=controlling the other).

Latitude and longitude are needed for the ACP sun up/down based controls of the relays.

Time zone sets current time zone. Should not include DST if automatic DST mode is enabled(see below).

DST start, Sunday and DST end, Sunday sets at which Sunday of the selected month the DST starts/ends. DST start, month and DST end, month sets on which months DST starts/ends. DST start, hour and DST end, hour sets at which hour on the day the DST starts/ends.  This function needs a configured SNTP server under IP Settings.

The example is set to start DST(=add one hour to the clock) the last Sunday in March at 2 am, and to end DST the last Sunday in October at 3 am, which is the rule for DST used in the European Union.

Enable HAM Radio functions is used to enable/disabled settings/menus used by radio amateurs.

Enable external help pages enables/disable integrated page specific help. The help pages can be reached by clicking the Show help button found in the upper right corner of each page. An example for the Advanced settings page is shown below:

New in version 3.0:

Temperature decimals is used to set number of decimals used when showing temperatures.

Temperature scale selects if the temperatures are shown in Celsius or Fahrenheit.

temperature.nu is used to get temperatures from the Swedish web site www.temperatur.nu The status of this service is shown on the “System Info” page.

New in version 4.0:

Use received Nexa codes is used when identical Nexa codes are shared between Nexa remote controls and the Webswitch. When using a Nexa  remote control the Webswitch will use the received code to match its programmed codes and if a match is found the Webswitch will set that Nexa remote’s status according to the code it received so that the status reflects the change caused by using the Nexa remote control.
