Operation
If the terminal function is activated, the
#X symbol is dis-
played in the header of the display as additional information on
the remote-controlled device, where "X" is the set device identifi-
cation of the remote-controlled device.
The displayed values and symbols are always accepted by the
selected device (e.g. mixer circuit T-HS of the RoCon M1 mix
valve module with device identification 1).
In order to operate the local device, it must be activated again in
the selection list ([No selection] parameter).
Activating/deactivating terminal operation
Prerequisite: a valid terminal ID has been assigned to the
RoCon B1 control panel of the ROTEX HPSU monobloc compact
or the RoCon U1 room station (
15 70 34
).
●
Set the rotary switch to the
"Remote Param"
position.
The "
Remote Param
" level is displayed.
●
Use the rotary button to select the [Bus - Scan] parameter.
●
Confirm the selection with a brief push of the rotary button.
The context menu is displayed.
●
Use the rotary button to select the [Bus - Scan] parameter and
confirm with "Yes".
Bus - Scan is performed.
An overview of all the devices found is displayed (for an
example, see fig. 3-10).
●
Use the rotary button to select the device for which the
terminal function should be carried out.
●
Confirm the selection with a brief push of the rotary button.
The local control unit functions as a remote control for the
external device.
To
end
terminal operation
and to switch back to the control unit
for the operation of the assigned device, the [
No selection

pa-
rameter must be selected and confirmed
at the
"
Remote
Param
" level
.
3.4.10 Operation with glycol
Frost can damage the system. To prevent the hydraulic compo-
nents from freezing, the software is equipped with special frost
protection functions, that include the activation of pump, internal
heaters, and/or backup heater operation in case of low tempera-
tures.
However, in case of a power failure, these functions cannot guar-
antee protection. It is therefore recommended to add glycol to the
water circuit. To do this, observe the installation and mainte-
nance instructions.
If glycol has been added to the system, the RoCon controller
setting must be adapted accordingly.
●
Set the rotary switch to the
"Configuration"
position.
An overview is displayed.
●
Use the rotary button to select the
"Setup"
level.
An overview is displayed.
●
Use the rotary button to select the [Glycol] parameter.
●
Change the parameter if desired.
– Parameter [Glycol] = 0: no glycol added
– Parameter [Glycol] = 1: glycol added
●
Confirm the selection with a brief push of the rotary button.
Change has been accepted. Jump back to previous dis-
play.
3.4.11 Whisper mode
Whisper mode means that the heat pump outdoor unit operates
at reduced output. This reduces the operating noise generated by
the heat pump outdoor unit.
Activating / deactivating whisper mode
●
Set the rotary switch to the
"Configuration"
position.
An overview is displayed.
●
Use the rotary button to select the
"System Configuration"
level.
An overview is displayed.
Fig. 3-11 Example of the display for the remote-controlled mixer module
If the "n.A." message is displayed in the rotary switch
setting
, no valid terminal ID has been assigned to
the control unit until now.
If the "n.A." message is still displayed, it may be necessary to
update the device software in order to use the terminal function.
Contact the ROTEX Service Team for this.
For setting the terminal ID of optionally connected
devices, see chap. 4.4 or the respective operating
instructions that are supplied.
After an interim disconnection from the power supply,
the display always appears at the "
Remote Param
"
level, as shown in fig. 3-9.
To be able to use the terminal function for connected devices, a
repeat Bus - Scan must be carried out.
Communication between the RoCon system components also
continues to function without a Bus - Scan, and previously un-
dertaken settings remain active.
The terminal function is activated as shown in fig. 3-10, but after
confirmation of the "Bus - Scan" display, the [New scan?] pa-
rameter must be selected with the rotary button and confirmed
with "Yes".
CAUTION!
During active whisper mode, the output in room
heating and room cooling mode decreases such
that it may no longer be possible to achieve pre-
set target temperature values.
●
With outside temperatures below freezing,
there is a risk of material damage caused by
frost.
