Eberle Universal thermostat Surface-mount 24 h mode 40 up to 100 °C 0524 72 143 294 プリント

The controller is suitable for universal use,
e. g. for:

Floor direct, floor storage or open area
heating systems, swimming pool control, air
conditioning.

The controller is suitable for:

– heating
– cooling

U

U (Terminal -5)

If the temperature measured by the sen-
sor (actual value) is below the setpoint,
the controller is switched ON (relay picks
up).
If the temperature measured is above the
setpoint, the controller is switched OFF
(relay in de-energized position).

P

P (Terminal -4)

If the temperature measured by the sen-
sor (actual value) is below the setpoint,
the controller is switched OFF (relay de-
energized).
If the temperature measured exceeds the
setpoint, the controller is switched ON
(relay picks up).

Apart from the setpoint, the temperature
at which the controller switches over
depends also on the hysteresis adjusted
(switching differential), see Fig. 1. It can
be changed by means of the adjuster
“hysteresis.“

d) Temperature setback 9:

(lowered setpoint) is effected by closing a

contact between termi-

nal 10-11, e. g. by means of an external
timer.

warns of sensor

failure.

This state is maintained until

the fault has been remedied. (Another variant
is available which will be in off state if a sen-
sor failure occurs).

Fix base of housing by means of the 4 holes
provided to a suitable surface. Enter cable for
power supply and load through the M 16
screwed glands. Enter cable for 

s

-switching contact and sensor through the

PG-16 screwed gland. Cut out

opening. Firmly tighten up screwed glands;
tightening torque is 25 Nm.
Tightly seal unused screwed glands using
suitable material.

Proceed as follows:
1. Remove cover by taking out 4 screws
2. Lever out cap at top of adjusting knob. 

See Fig 2

3. Slacken screw and pull off adjusting knob
4. Push spindle down into the interior
5. Firmly press the closure plug supplied into

the hole from the outside (see Fig. 3)

6. Re-place cover.

Cable for sensor and s-contact:

Use screened cables where leads are installed
in cable ducts or where they are run in parallel
with power cables for some distance.

May be extended to a maximum of 

with 1.5 mm

2

conductor area.

For s-contact:

May be extended to a maximum of 10 m with
1.5 mm

2

conductor area.

Cable diameter: 8.6 mm ±0.3 mm.

When installing the sensor, make sure that
satisfactory contact exists with the heat
source. The sensor should be able to follow
the temperature changes in the medium to be
controlled.
When installing the 

in liquid media or in areas where access is
difficult, it is absolutely necessary to provide a
protective tube (to facilitate replacement).
A

should contact the

pipe as fully as possible.
In the case of 

care should be

taken to ensure that the slot openings are
positioned in the direction of the air flow.
For 

refer to the circuit

diagram provided inside the controller. All
leads to the controller must be fixed in place.

The timer contact must be floating (basic
insulation); 

of sever-

al timer contacts is 

Never apply mains voltage to a 

timer contact (this will cause destruction of
the controller).

In order to qualify for degree of protec-
tion class IP 65, it is necessary that the
closure plug should be pressed in solid-
ly with the rubber gasket.

*Also for switching safety extra-low voltage (SELV)

The separately mounted unit must not be
opened except by authorised persons, and
this should not be attempted unless it is
isolated from the power supply. For the
connections refer to the circuit diagram
provided inside the cover. It is mandatory in
all work on the unit to observe the current
safety regulations of the VDE, or its nation-
al equivalent, and those of the local power
supply companies. 
In order to qualify for protection class II, it is
necessary to comply with the guidelines of
VDE 0100, or national equivalent standards.
