Configuration Parameters
Parameter no. 1 & no. 2 – Input I1 & Input I2 switch type
Available configuration parameters (data type is 1 Byte DEC):
- default value 1
- 0 - mono-stable switch type (push button)
- 1 - bi-stable switch type
Parameter no. 11 & no. 13 - Automatic turning off output Q1 & Q2 after set time
TVs, Hi-Fi systems and other home appliances have already integrated automatic turn off functionality, this device also offers this functionality. Automatic turning off function allows energy saving, without doing scenes on Z-Wave controller.
This function, for example also allows automatic re-locking door after defined time.
When relay Q1 or Q2 is ON it goes automatically OFF after time defined by this parameter. Timer is reset to zero each time the device receives ON command regardless from where it comes (push button, associated device, gateway, controller, etc.).
Available configuration parameters (data type is 2 Byte DEC):
- Default value 0
- 0 - Auto OFF disabled
- 1 – 32535 = 1 second (0,01 s) – 32535 seconds (325,35 s) Auto OFF enabled with define time, step is 1 s or 10 ms according to parameter nr. 15
Parameter no. 12 & no. 14 - Automatic turning on output Q1 & Q2 after set time
When relay Q1 or Q2 is OFF it goes automatically ON after time defined by this parameter. Timer is reset to zero each time the device receives OFF command regardless from where it comes (push button, associated device, gateway, controller, etc.).
Available configuration parameters (data type is 2 Byte DEC):
- Default value 0
- 0 - Auto ON disabled
- 1 – 32535 = 1 second (0,01 s) – 32536 seconds (325,35 s) Auto ON enabled with define time, step is 1 s or 10 ms according to parameter nr. 15
Parameter no. 21 – Enable/Disable Double click function
If Double click function is enabled, a fast double click on the push button will set dimming power at maximum dimming value. Available configuration parameters (data type is 1 Byte DEC):
- Default value 0
- 0 – double click disabled
- 1 – double click enabled
Parameter no. 15 - Automatic turning off / on seconds or milliseconds selection
Available configuration parameters (data type is 1 Byte DEC):
- Default value 0
- 0 – seconds selected
- 1 – milliseconds selected
Note: This parameter is valid for both outputs Q1, Q2 and is the same for turning off or on.
Parameter no. 30 - Saving the state of the relays Q1 and Q2 after a power failure
Available configuration parameters (data type is 1 Byte DEC):
- default value 0
- 0 – Flush 2 Relay device saves its state before power failure (it returns to the last position saved before a power failure)
- 1 - Flush 2 Relay device does not save the state after a power failure, it returns to "off" position.
Parameter no. 40 & no. 41– Power reporting in Watts on power change for Q1 or Q2
Set value means percentage, set value from 0 – 100 = 0 % - 100 %. Available configuration parameters (data type is 1 Byte DEC):
- default value 10
- 0 – Reporting Disabled
- 1 – 100 = 1 % - 100 % Reporting enabled. Power report is sent (pushed) only when actual power in Watts in real time changes for more than set percentage comparing to previous actual power in Watts, step is 1 %.
Note: If power changed is less than 1 W, the report is not sent (pushed), independent of percentage set.
Parameter no. 42 & no. 43– Power reporting in Watts by time interval for Q1 or Q2
Set value means time interval (0 – 32535) in seconds, when power report is sent. Available configuration parameters (data type is 2 Byte DEC):
- default value 300 (power report in Watts is sent each 300 s)
- 0 – Reporting Disabled
- 1 – 32535 = 1 second – 32535 seconds. Reporting enabled. Power report is sent with time interval set by entered value.
Parameter no. 63 & no. 64 – Output Q1 & Output Q2 Switch selection
Set value means the type of the device that is connected to the PWM output. The device type can be normally open (NO) or normally close (NC). Available configuration parameters (data type is 1 Byte DEC):
- default value 0
- 0 - When system is turned off the output is 0 V (NC).
- 1 - When system is turned off the output is 230 V (NO).
Temperature Sensor Setting
Parameter no. 110 – Temperature sensor offset settings
If the temperature sensor is connected to the device, the temperature sensor widget is shown automatically in UI (user interface).
If the measured temperature with an additional temperature measuring device is different from the one measured by the connected digital temperature sensor, the temperature can be compensated by this parameter.
Available configuration parameters (data type is 2 Byte DEC):
- default value 32536
- 32536 – offset is 0.0 °C
- From 1 to 100 – value from 0.1 °C to 10.0 °C is added to actual measured temperature.
Parameter no. 120 – Digital temperature sensor reporting
If digital temperature sensor is connected, device reports measured temperature on temperature change defined by this parameter.
Available configuration para meters (data type is 1 Byte DEC):
- Default value 5 (Temperature is reported on 0.5 °C change)
- 0 – Reporting disabled
- 1- 127 = 0.1 °C – 12.7 °C, step is 0.1 °C
