INTRODUCTION
The Vokera RC05 remote control enables full control
of the Linea, Compact and Hydra range of boilers.
The RC05 can also be used as a programmable room
thermostat and has a facility for the connection of an
external temperature sensor.
INSTALLATION REQUIREMENTS
To enable the correct functioning of the RC05, the
following instalaltion requirements must be adhered to:
the installation of the RC05 and the external sensor
(if required), must only be carried out by suitably
qualified personnel
the sensor should be mounted on an internal wall
away from any source of heat and/or confined
space (fig. 1)
the connecting cable length between boiler and
control panel should not exceed 50-metres
ideally, the RC05 should be mounted directly to a
single-gang box. The RC05 can also be wall-
mounted, however tha cabling will require to be
flush with the finished wall surface as the RC05 is
not suitable for surface wiring
all wiring between the RC05 and the appliance must
conform to BS6500 and sized from 0.5 to 1.0mm2
the RC05 should be mounted approximately 1.5-
metres above floor level
the RC05 when used with an external sensor, may
not be suitable for systems that incorporate fan
warm air heaters.

1. INSTALLATION OF RC05 (fig’s. 2, 3 & 4)
Remove the RC05 from the packaging and detach
the panel from it’s wall mounting plate.
Using the wall mounting plate as a guide, mark the
position of the fixing holes on the chosen location for
the RC05.
Drill two 6mm-diameter holes at the previously
marked positions on the wall.
Route the wiring through a suitable cable entry point
ensuring that the wiring does not become trapped.
Using the screws and wall plugs provided, secure
the mounting plate to the wall.

2. WIRING CONNECTIONS (Linea)
Isolate the appliance from the electrical supply and
remove the appliance casing and input PCB cover
(fig. 3 & 4). Refer to the installation instructions for
details. Connect a suitable cable between te S & -
terminals of the RC05 and the S & - terminals of the
control PCB (see fig.5). Remove the link-wire (if fitted)
between terminals TA & TA of the control PCB.
Refer to paragraph 4.2 if an external sensor (part no.
2359259) is also being connected.
Once the wiring connections have been completed
re-attach the RC05 to the wall mounting plate.
The PCB cover and appliance casing can now be
refitted.
2. WIRING CONNECTIONS (Hydra)
The RC05 must be used with the Hydra remote
control interface (part no.410). Carry out the
installation of the interface as detailed in the
instructions supplied.
Connect the RC05 to the remote control interface as
shown in fig. 6.
If an external sensor (part no. 2359259) is also being
connected, refer to the instructions supplied with the
sensor.
Once the wiring connections have been completed
re-attach the RC05 to the wall mounting plate.
3. WIRING CONNECTIONS (Compact)
The RC05 must be used with the Compact remote
control interface (part no.409). Carry out the
installation of the interface as detailed in the
instructions supplied.
Connect the RC05 to the remote control interface as
shown in fig. 7.
Refer to paragraph 4.2 if an external sensor (part no.
2359259) is also being connected.
Once the wiring connections have been completed
re-attach the RC05 to the wall mounting plate.
4. ADDITIONAL FUNCTIONS
The RC05 is equipped with additional functions.
These functions enable the RC05 to be used with an
external sensor, underfloor heating systems and
calibration of the unit.
F1 - Frost Protection Circuit. When enabled, this
function will allow a heat request should the room
temperature (the room in which the RC05 is
located) drop below 6.6°C.This function is not active
when the RC05 is used for boiler only control.
F2 - Thermo-regulation. When enabled, this
function automatically adjust the outlet flow
temperature based on the current temperature of
the external sensor.
F3 - Under-floor heating. When enabled, this
function fixes the maximum flow outlet temperature
to 40.0°C.
F4 - Service Scheduling. When enabled, this
function will alert the end-user that the appliance
requires it’s annual service.
F5 - Internal Sensor Calibration. Used to calibrate
the indoor sensor.
F6 - External Sensor Calibration. Used to calibrate
the exteral sensor (Linea/Compact only).
F7 - Alarm History. Used to display the last 5 alarm
codes generated by the boiler.

4.1 ENABLING/DISABLING ADDITIONAL
FUNCTIONS
To access the RC05 additional functions, set the
control to the OFF position (see fig. 8).
Press and hold the PROG button for 10-seconds, F?
will now appear on the display (see fig. 9).
To access the functions press ENTER within 10-
seconds (see fig. 10).
Use the ENTER button to scroll to the required
function (F1 to F7). Use the +/- buttons to enable (1)
or disable (0) the selected function (F1 to F3), to set
the service schedule (F4) or to calibrate the sensors
(F5 & F6).

4.2 EXTERNAL SENSOR
When the external sensor is connected to the RC05
(Linea & Compact only) a temperature curve can be
set to suit the system and location (fig. 13). Connect
the sensor to the EXT terminals of the RC05 (see
fig. 11).
Use the water temperature and +/-adjustment
buttons to select and store the required curve (fig.
12). Curve ‘C5” is the default setting.
5. REPLACING THE BATTERY
The RC05 is supplied with long-life battery (CR1220)
that is already inserted and activated. The battery
should last for approximately 4-years.
Should it be necessary to replace the battery, the
following procedure should be used:
isolate the appliance from the electrical supply
remove the RC05 control panel from its wall-
mounting plate
*remove the jumper tag from JP1
*remove the battery from its location and *insert
the new battery (observing correct polarity)
*refit the jumper tag to JP1
refit the RC05 control panel to the wall-mounting
plate
restore the electrical supply.
