Object: "Status switch": 1 bit (EIS1)
This object is visible if the status response has been activated in the
parameter settings. It reports the switching state of the output. The object
value is sent in the event of a change.
When the heating actuator is controlled via a 1-byte object, the behaviour of
the object can be set in the parameter "Transmit status response":
"current state of the output"
Telegram value
"0% = OFF, otherwise = ON"
Telegram value
Object: "Forced operation": 1 bit (EIS1)
This object sets the output to a defined state and blocks it. On receipt of the
value "1", the forced operation is activated and the output triggers the
parameterised valve position. On receipt of the value "0", the forced
operation is finished. The object is enabled in the parameters.
Object: "Trigger valve purge": 1 bit (EIS1)
On receipt of the value "ON", the valve is opened for the duration of the
valve purge. On receipt of the value "OFF", the valve purge is ended. This
object is visible if the purge function has been enabled in the parameters.
Object: "Status valve purge": 1 bit (EIS1)
This object indicates that the valve purge is active.
Telegram value
Object: "Telegr. fault thermostat": 1 bit (EIS1)
This object indicates a possible fault of the room thermostat. The object
"Switch" or "Control value (PWM)" can be monitored cyclically. If the object
value is not available for an adjustable period, the device assumes that the
room thermostat has failed and reports a fault.
Telegram value
Object: "Telegr. status byte": 1 byte (non EIS)
This object is only visible for the Electronic Switch Actuator Modules ES/M
2.x.1. It provides more detailed information about the operating state of the
device. The object value is sent when there is a change in the value.
bit
Meaning
0 (LSB)
Overload (e.g. short circuit) at output A
1
Overload (e.g. short circuit) at output B
2
Not used, always "0"
3
Not used, always "0"
4
Not used, always "0"
5
Not used, always "0"
6
Supply voltage available
7 (MSB)
Type of supply voltage: 0 = AC; 1 = DC
A detailed table to classify the object value can be found in section 5.1.
"0"
Valve is closed
"1"
Valve is opened
"0"
Valve is closed (0%)
"1"
Valve is not closed
(1% ... 100%)
"0"
Valve purge is not active
"1"
Valve purge is active
"0"
No fault
"1"
Fault
50
