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. 18
19 Special situations ź ź ź ź ź 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-2thermometer 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-2thermometer 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.
