Project design and programming
Objects for the "Master" function
No Function
0/15 Control value heating
The heat output is preset by the room thermostat via this object.
1/16 Control value cooling
The cooling capacity is preset by the room thermostat via this object.
2/17 Speed limitation
Used to limit the fan speed to a maximum value.
3/18 Forced operation
Sets a fixed fan speed and valve position for the fan coil controller and disables them
4/19 Toggle heating/cooling
In the operating mode "2-pipe system, heating and cooling", it gives the fan coil controller the
information about whether hot or cold water is being supplied.
5/20 Slave fan speed 2
6/21 Slave fan speed 3
7/22 Slave fan speed 3
8/23 Slave fan speed 5
The master output controls further outputs via these objects which are used to control the
ventilation.
9/24 Slave valve
Visible when controlling a 2-pipe system. Via these objects, the master controls a slave
output which in turn controls the valve.
9/24 Slave valve heating
Visible when controlling a 4-pipe system. Via these objects, the master controls a slave
output which in turn controls the valve for the heating circuit.
10/25 Slave valve cooling
Visible when controlling a 4-pipe system. Via these objects, the master controls a slave
output which in turn controls the valve for the cooling circuit.
11/26 Telegr. fault thermostat
Indicates a possible fault of the room thermostat. The fan coil controller is in the safety
position.
12/27 Status switch
This object reports the current state of the output.
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 for the "Slave" function
No Function
0/15 Fan coil slave
This object is used to control the output via the master.
