yes:
Three 1 bit communication objects
Speed 1
,
Speed 2
and
Speed 3
are enabled.
The Fan Coil Actuator receives a setting telegram via these communication
objects.
Telegram value
1 = fan speed x is switched on
0 = fan speed x is switched off
If several ON/OFF telegrams are received consecutively in a short period of
time at various
Fan speed 1-3
communication objects, the value last
received by the fan control is the decisive value.
An OFF telegram to one of the three communication objects
Fan speed 1-3
,
switches off the fan completely.
Important
The forced operation remains valid and is considered.
The parameterised minimum dwell time in the fan speed for automatic
mode is ignored during manual operation. Accordingly, an immediate
reaction to the manual operation is detected.
The delay time with speed switch over remains active to protect the fan.
