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 2025 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
2025 RTH regulator
and/or the T-2 thermometer without a significant deterioration of thermal
comfort conditions in the controlled spaces.

The AURATON 2025 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 2025 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.
Configuration settings:
backlight colour, hysteresis, delay, offset
Configuration settings are presented for changing in the following order:
To enter the configuration settings change mode press the‚ buttons
simultaneously and hold them for 5 seconds until the display backlight starts
flashing.
1 . BACKLIGHT COLOUR CHANGE :
Flashing backlight indicates that you
can change the backlight colour with
the
buttons.
Confirm the setting by pressing the
button.
The regulator will proceed to change
the next parameter.
2 . HYSTERESIS CHANGE:
Hysteresis is designed to prevent switching the controlled device on and
off too frequently due to minute fluctuations of temperature.
E.g. for the HI 2 hysteresis, when the temperature is set to 20°C, the boiler
will be switched on at 19.8°C, and switched off at 20.2°C. For the HI 4
hysteresis, when the temperature is set to 20°C, the boiler will be switched
on at 19.6°C, and switched off at 20.4°C.
The hysteresis change mode is signalled
by flashing text “HI”. You can change
hysteresis settings with the
buttons.
HI 2 – ±0,2°C
HI 4 – ±0,4°C
Confirm the setting by pressing the
button.
The regulator will proceed to change the
next parameter.
