Unusual situations

ź
After the loss of 3 subsequent transmissions (after 15 minutes) from the
T-1 controller and/or T-2 thermometer signaling the failure will take
place on the RTH receiver (continuous LED flashing alternately with red
and green light). Until the removal of the problem the RTH receiver goes
into the remembered ON/OFF cycle from the last 24h.
ź
When both signals come back (T-1 controller and T-2 thermometer), the
error is deleted and the receiver goes into normal operation.
ź
As soon as the signal from the T-2 thermometer returns, the receiver
uses the last remembered setting and maintains it, still signalling failure.
ź
When we have H-1 handles or window position sensors, T-2
thermometer and T-1 controller (temperature is measured by the T-2
thermometer) associated with the receiver, maintaining the operation
cycle from the last 24h will take place only after loss of signal from the T-2
thermometer. When there is no signal only from the T-1 controller the
RTH receiver automatically maintains the most recently remembered
setting of the T-1 controller but also signals failure.
ź
When we have only H-1 handles associated with the RTH receiver and
associated the T-2 thermometer without the T-1 controller, the RTH
receiver will maintain constant temperature factory set at 20°C. If we
slightly open any window with associated, H-1 handle, the temperature
of 17°C will be maintained. If any window with associated H-1 handle
will be opened the RTH receiver will turn off the heating device, but it will
activate it again if the temperature falls below 7°C.
ź Switching of the transmitter is synchronized with the course of power supply
network 230 V so as to ensure that short circuit and opening of contacts of the
transmitter always proceeds close to the passage of the course of system voltage by
zero. It prevents the formation of an electrical arc and significantly increases
durability of the transmitter.
ź The AURATON RTH receiver is equipped with a unique algorithm of ON-OFF cycle
analysis. The whole heating cycle from the last 24h is saved in the memory of the
RTH receiver. In the case of loss of communication with the T-1 controller and/or the
T-2 thermometer, the RTH receiver will automatically perform the remembered
ON/OFF cycle from the last 24h. It gives time to restore the transmission (removal of
interruptions) or repair the T-1 controller and/or the T-2 thermometer without
significant thermal comfort deterioration in the controlled facility.
