In gas fired combination boilers, the analog
room thermostat ART complies with the
following Directives:
- Low Voltage Directive: 73/23/EEC
- EMC Directive: 89/336/EEC
Terminology / Standards and regulations
Standards and regulations
Terminology
Heating water temperature
The heating water temperature is the radiator
flow temperature. The higher the heating water
temperature, the higher the heat transfer to
radiators.
Boiler
Gas fired boiler, which can be combined with a
DHW cylinder.
Combination boiler
Gas fired boiler with an instantaneous water
heater and DHW QuickStart.
DHW loading
Heating up the DHW cylinder.
DHW QuickStart
The heating water in the boiler will be held at
a certain temperature during summer mode,
to be able to supply hot water as rapidly as
possible from the instantaneous water heater
of the combination boiler. The day program
switches this function ON and OFF during
summer mode.
Heating program
Subject to program selection, the day program
switches the gas fired boiler from heating to
economy mode or from heating mode to
heating OFF and vice versa.
Domestic hot water program
In a combination boiler, the day program
controls the DHW QuickStart, and for a boiler
with a DHW cylinder, it switches the cylinder
loading ON and OFF.
Winter mode
Central heating and DHW according to the
day program.
Summer mode
Central heating OFF, DHW according to the
day program.
Heating mode/economy mode
In winter mode, two room temperatures can
be selected. One for central heating mode and
one for economy mode, when the room
temperature will be setback to economy
temperature.
The day program changes over between
heating and economy mode.

Installation
- Install the ART on an internal wall at a height
of approx. 1.5 m.
- Install the ART in a living room, which is
representative of the entire living
accommodation.
- The ART must not be subject to draughts or
radiated heat.
- The ART must not be blocked by furniture or
curtains.
- In this room, all radiator valves must be fully
opened.
Installation / BUS interface setting
Remove the ART from its base using a screwdriver
- Lever the ART top from its base using a
screwdriver .
In doing so, insert the screwdriver into the
lower cutout of the base, and lever the base
at the terminal strip.
- Secure the base through the fixings holes.

Please note: All accessory controllers (BUS users) must be set to the same boiler interface.
Wolf boilers are equipped either with an e-BUS or a SCOM interface for control accessories. The
interface can be selected with the DIP switches on the back of the ART.
BUS interface setting
For boilers with eBUS interface, the BUS
terminals are marked “+“ and “-“ together with
“eBUS“.
The interface address for eBUS is set at the
factory (DIP switch 4 is set to “ON“, switches 1
to 3 are set to “OFF“).
Connection to Wolf boilers with eBUS interface
For boilers with SCOM interface, the BUS
terminals are marked “+“ and “-“ in accordance
with connection diagrams together with
“(Wolf) Accessory“ (DIP switches 1 to 4 are set
to “OFF“).

Pasteurisation (P 04) (only with eBUS
in conjunction with a boiler with DHW
cylinder)
Pasteurisation is switched OFF when factory
settings are active (parameter P 04 = 00).
Pasteurisation is active if parameter P 04 is set
to 01.
The DHW cylinder will be heated to 65 °C once
every day for one hour after DHW loading has
been enabled, if pasteurisation has been
activated.
Parameter P 04 will be displayed during eBUS
communication.

Automatic summer and winter
changeover
The ART will automatically change over to
summer mode (heating circuit pump is switched
OFF), if the room temperature rises 1K above
the set room temperature. The system
automatically reverts to heating mode (heating
circuit pump is switched ON), when the actual
room temperature falls below the set room
temperature. Note: In summer mode, the status
display shows or .
Controller reset
The ART processor is restarted by pressing
“Reset“. The display indicates the software
number, version and all symbols in sequence.
Loading the standard configuration
Hold down key and briefly press “Reset“. The
software number and version and then EEP
are displayed. The ART is then reset to its factory
settings.

Fault code Explanation
91 Wrong address set - ART
Fault code display
Fault code 91: In systems with several controllers,
two (e.g. AWT, ART) are set to the same BUS
address. Correct the address settings using the
DIP switches on the respective controllers.
Check the installation instructions of the
respective boiler for an explanation of all other
fault codes.
If the device will not operate properly after the
boiler has been reset twice, or if the boiler
cannot be reset, inform your heating
contractor of the fault code displayed.
Fault codes
Any fault of the gas fired boiler will be
indicated by a flashing fault code number and
the warning symbol in the ART display.
