Each and every change to thermostat status (switching the heating on/off) is executed by the
receiver instantly, whereas the signalization confirming the reception of the radio signal from
the transmitter is repeated every 15 minutes.
8.1.
Strength of radio signal
Information on the strength of the radio signal is communicated together with the signalization
of the reception signal from the transmitter. The reception of the radio signal is signaled in
greed. Three flashes of the LED stand for exceptionally good reception, two flashes stand for
good reception, and one flash
–
for sufficient reception.
8.2.
Lack of radio communication
If the communication between the thermostat and the receiver is interrupted (e.g. discharged
batteries) and such status lasts for 2 minutes (no response from the receiver) then the
receiver switches into the frost protection mode. The heating device will be switched on for 20
minutes every 3 hours so that the rooms are not cooled down. At the time of re-establishing
communication (replacement of batteries), the receiver turns the system off and automatically
resumes the operation.
Lack of radio communication is signaled by a fast flashing green LED.
8.3.
Continuous operation of the heating device (MAN)
In the case of system failure, it is possible to switch the system on manually. Move the switch
on the RX receiver to the MAN position. Such status is signaled by fast flashing red LED (in the
heating mode) or blue LED (in the cooling mode).
