Led Indicator - ESBE GDA111 Notice D'utilisation

After a complete filling and venting, turn the screw on the check valve back to it´s
normal operating position, picture 2 and set the circulation pump operation to
recommended position. See chapter 5 Wilo and chapter 6 Grundfos.
COMMISSIONING ACTUATOR:
During commisioning it might be useful to turn the valve manualy by pulling the
knob, picture A. Reset to operation mode by pushing and adjusting the knob back,
picture B.

COMMISSIONING CONTROLLER:
For more information regarding comissioning, read CRC, CRD or 90C instruction
manuals enclosed.
COMMISSIONING IF USING LARGER SYSTEMS/CENTRAL REGULATING
Please read each product´s instruction manual.
COMMISSIONING FIXED TEMPERATURE OPERATION
To set the mixed water temperature, see recommendations in the table below.
All temperature settings must be measured at suitable location with a
thermometer to have the correct mixing temperature of the valve.
20 - 43°C 20°C 27°C
The temperatures are only a reference and might be different under certain conditions.
However the range will be kept.

- CIRCULATION PUMP
OPERATION MODE
All functions can be set, activated or deactivated by using the operating knob.
The circulation pump is equipped with a LED indicator in order to display the
circulation pump operating status. More information in table "Faults, causes and
remedies" page 5
SETTING THE CONTROL MODE
To select the desired control mode turn the operating knob.
Recommended setting: Δp-v in the middle position,
as displayed in the figure.
At commissioning of radiator systems with circulation units equipped with a controller,
all radiator valves initially should be fully opened. The set temperature of the control-
ler should be adjusted to achieve the desired temperature in the coldest room. If
some rooms tend to be too hot, the radiator valves in those rooms afterwards might
be adjusted to achieve the desired room temperature.
31°C 35°C 39°C 43°C

LED indicator

In most cases it is suitable to position the red knob in the middle position to the
left (ΔP-v) to get the appropriate capacity from the circulation pump, especially
when radiators are used.
In some cases this setting has to be adjusted: If much
sound occurs from the radiator system, the capacity of
the circulation pump might be too high and the red knob
should be slightly turned towards the min position.
If room temperature decrease when it is very cold outside,
the red knob should be slightly turned toward the max
position.
When using applications like floor heating with room ther-
mostats, the performance might be improved by choosing
to turn the knob to the right side (ΔP-c).
Start in a middle position.
VARIABLE DIFFERENTIAL PRESSURE (ΔP-V) :
The differential-pressure set point H is increased linearly over the permitted
volume flow range between ½ H and H. This control mode is especially useful in
heating systems with radiators, since flow noise at the thermostatic valves is
reduced.
CONSTANT DIFFERENTIAL PRESSURE (ΔP-C):
The differential-pressure set point H is kept constant over the permitted volume flow
range at the selected differential-pressure set point up to the maximum circulation
pump curve. ESBE recommends this control mode for underfloor-heating circuits
or older heating systems with large-sized pipes as well as for all applications with no
changeable pipe system curve, e.g. boiler charge circulation pumps.

FILLING AND VENTING FUNCTION
Fill and vent the system correctly. If direct venting of the
rotor chamber is required, the venting function can be
started manually. By turning the operating knob to the
symbol for venting in the middle position, the venting
function is activated after 3 seconds.
The venting function lasts 10 minutes and is indicated with quick green LED
blinking. Noises may be heard when the venting function is running. The process
can be stopped if desired by turning the knob. After 10 minutes, the circulation
pump stops and goes automatically in Δp-c max mode.
WARNING! Dont forget to turn the knob back to recommended setting!
NOTE: The venting function removes accumulated air from the rotor chamber
of the circulation pump. The venting function of the circulation pump does not
necessarily vent the heating system.
During automatic venting function (10min) the circulation pump alternates
between high and low speeds in order for air bubbles to be released from the
rotor and transported to the venting valve of the installation.
