If at this point none of the heating controller channels is connected, the bind-
ing LED flashes.
Pressing the binding button displays the state of the individual chan-
nels. LEDs for connected channels are lit. The LEDs of the channels
not connected remain dark. When releasing the button, the heating
circuit controller returns to normal operation after 7 seconds. When a
channel is selected, the binding LED indicates the status of the re-
spective channel.
Example: Heating circuit controller RRV912
= LED and function button to test connection, for binding and factory setting
NC 3P NO = Actuator type selector switch
CH = Channel selection button
B = LED for universal input channel
U = LED for 0..10 V universal output channel (RRV912 only)
Q = LEDs for universal relay output channels
Y = LEDs for heating circuit controller channels
The heating circuit controller is connected individually to each required channel.
The actuator type must be set at the actuator type selection switch of heating
circuit controller RRV91…. prior to connecting the heating circuit controller
channels (Yx).
NC Thermal 2-position actuator, NC.
NO Thermal 2-position actuator, NO.
3P Electric motor-driven 3-position actuator (RRV912 only). Channel
Y1 has the function Actuator OPEN and channel Y2 the function
Actuator CLOSE. Both LEDs Y1 and Y2 are lit simultaneously dur-
ing channel selection.
The selection switch setting acts on all control circuit outputs of the
heating circuit controller at the same time. You cannot configure dif-
ferent actuator types within a device for the control circuit outputs. Us-
ing the selection switch resets the device regardless of the heating
circuit controller operating state.
If the heating circuit controller channels of the RRV912 are connected
to the central apartment unit, do not retroactively switch from 2 to 3-
position actuators or vice-versa using the selection switch. Separate
the heating circuit controller channels prior to switching the actuator
type from 2 to 3-position.
Switching between NC and NO works for previously connected heat-
ing circuit controller channels.
