Special situations

When 3 consecutive transmissions (after 15 minutes) from the

AURATON

200 RTH

regulator and/or the

T-2

thermometer are lost, an error is

signalled on the

RTH

receiver (LED flashing continuously red and green).

The

RTH

receiver starts executing the ON - OFF cycle memorised during

the last 24 hours of operation until the problem is removed.

When both signals return (from the

AURATON 200 RTH

regulator and

the

T-2

thermometer), the error is cancelled and the receiver enters its

normal mode of operation.

When only the

T-2

thermometer signal returns, the receiver uses the last

memorised setpoint value and maintains it while signalling the error.

When the

H-1

handles, the

T-2

thermometer and the

AURATON 200 RTH

regulator (the temperature is measured with the

T-2

thermometer) are

paired with the receiver, then maintaining the work cycle from the last 24
hours occurs only after losing the signal from the

T-2

thermometer. When

only the signal from the

AURATON 200 RTH

is missing, the RTH receiver

automatically maintains the last memorised setpoint from the

AURATON

2025 RTH

regulator and also signals an error.

When you have only the

H-1

handles and the

T-2

thermometer paired with

the

RTH

receiver without the

AURATON 200 RTH

regulator, the

RTH

receiver maintains a constant, factory-defined temperature of 20 °C. If you
pivot any window equipped with the

H-1

handle paired with the receiver,

a temperature of 17 °C is maintained. If you open any window equipped
with the

H-1

handle paired with the

RTH

receiver, the receiver switches off

the heating device, but will switch it back on when the temperature falls
below 7 °C.

Switching the relay is synchronised with the wave of the 230 V mains voltage

in order to ensure that closing and opening contacts of the relay occurs
around the zero-crossing point. This prevents the occurrence of an electric
arc, significantly extending the relay service time.

The

AURATON RTH

receiver is equipped with a unique algorithm for

analysing the ON - OFF cycles. The entire heating cycle from the last 24 hours
is recorded in the memory of the

RTH

receiver. In the event of losing

communication with the

AURATON 200 RTH

regulator and/or the

T-2

thermometer, the

RTH

receiver automatically executes the ON - OFF cycle

memorised during the last 24 hours. This provides time for restoring
transmission (removing interferences) or fixing the

200 RTH

regulator

and/or the

T-2

thermometer without a significant deterioration of thermal

comfort conditions in the controlled spaces.

Cooperation with optional devices (the

AURATON T-2

thermometer,

the

AURATON H-1

window handle).

Additional information and notes

ź
ź

The controller can be switched on or off at any time by holding the key
pressed for a while.

Pressing any function key for the first time always starts

the backlight first, and then the key function is performed.

While programming any function, if no key is pressed for 10 seconds, this

will be interpreted as pressing the key.

The

AURATON 200 RTH

regulator and/or the

T-2

thermometer must be

installed at least 1 metre from the

RTH

receiver (too strong a signal from the

transmitters can cause interference).

At least 30 seconds must elapse between switching the relay off and on.
Data transmission from the

AURATON 200 RTH

regulator to the receiver

occurs upon each change of 0.2 °C of the surrounding temperature. When
the temperature is stable, the regulator sends heart-beat data every 5
minutes (which is signalled with the LED blinking orange on the

RTH

receiver).

In the event of a power outage, the

RTH

receiver will switch off. When power

is restored, the heating device is switched on automatically, and the

RTH

receiver awaits a signal from the paired transmitters (this signal should be
received within 5 minutes of restoring power). After receiving the signal, the

RTH

receiver enters the normal mode of operation.

The

RTH

receiver cannot be placed in metal containers (e.g. an assembly

box, a metal enclosure of a heater) in order to not to interfere with its
operation.
