When 3 consecutive transmissions (after 15 minutes) from the AURATON
2025 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 2025 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 2025 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 2025 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 2025 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.
RESET of the regulator
Pressing the RESET button ( ) causes the time and day setting to be erased,
and the regulator to be restarted.
MASTER RESET of the regulator
The MASTER RESET function restarts the regulator and restores factory
settings. This function is invoked by pressing the and RESET buttons
simultaneously.
NOTE: All user-defined programs will be erased!

Cooperation with the AURATON 2025 RTH regulator and/or
the AURATON T-2 thermometer as well as the AURATON H-1 handles
By default, the AURATON RTH receiver does not have any AURATON H-1
handle or AURATON W-1 window position sensor paired, therefore the relay
is controlled by the paired AURATON 2025 RTH regulator and/or
the AURATON T-2 thermometer. When at least one H-1 handle is paired with
the RTH receiver, the relay is controlled in the following manner:
A) The window is closed or trickle-ventilated (micro-ventilation).
When the H-1 window handles is paired with the receiver, and all
windows are closed or trickle-ventilated, the relay still maintains the
setpoint from the paired AURATON 2025 RTH regulator and/or the
T-2 thermometer.
B) The window is pivoted.
If at least one window is pivoted, the temperature set in the AURATON
2025 RTH regulator is lowered in AURATON RTH receiver down to 3 °C.
This state will be maintained until closing. This state will last until all
windows are closed or trickle-ventilated.
C) The window is opened.
When you open a window equipped with the H-1 handle paired for
longer than 30 seconds, the relay in the AURATON RTH receiver
is switched off, as is the connected heating device. If all the assigned
windows are again in a state other than “opened”, the RTH receiver
returns to normal cooperation with the AURATON 2025 RTH regulator
and/or the T-2 thermometer no earlier than 90 seconds after switching
off the relay. The purpose of this delay is to prevent too rapid transitions of
the connected heating devices between the ON and OFF states. However,
if the temperature in the room drops below 7 °C, the relay inside the
receiver is switched on regardless of the positions of windows in order to
prevent the room from freezing.
D) The signal is lost.
When the RTH receiver has lost the signal from the H-1 handle paired (3
consecutive transmissions are lost), it changes the status if this window to
“closed”. When the transmission is restored, the H-1 handle is again
properly read off by the RTH receiver.
