No Function
0/15 Switch
Switches the output directly:
"0": Valve closes
"1": Valve opens
0/15 Control value (PWM)
Determines the control value of the valve via the interpulse ratio (pulse width modulation) of
the output.
1/16 Status switch
Reports the switching state of the valve control (valve is opened / closed).
3/18 Forced operation
Sets the output to a defined state and disables it.
This object is visible if 1-bit forced operation is enabled in the parameters. On receipt of the
value "1", the forced operation function is activated and the output triggers the set valve
position. The forced operation is finished on receipt of the value "0".
4/19 Trigger valve purge
This object is visible if the purge function is enabled in the parameters. On receipt of the
value "1", the valve is opened for the duration of the valve purge. The valve purge is ended
on receipt of the value "0".
5/20 Status valve purge
Indicates that the valve purge is active.
11/26 Telegr. fault thermostat
Indicates a possible fault with the room thermostat.
29 Telegr. status byte
This object provides further information about the operating state of the device (only
Electronic Switch Actuator Modules ES/M 2.x.1).
Object: "Switch": 1 bit (EIS1)
This object is visible if the control of the heating actuator is carried out via a
1-bit object. The output is controlled directly, regardless of whether the valve
is normally open or normally closed.
Telegram value
Object: "Control value (PWM)": 1 byte (EIS6)
This object is visible if the control of the heating actuator is carried out via an
8-bit object e.g. within continuous-action control. The object value [0..255]
determines the control ratio ("interpulse period") of the valve. The valve is
closed at object value 0 and fully opened at object value 255.
