generated based on an incoming call
(e. g. for a gate opening)
Phone calls are redirected
for the SIM card which is
inserted in GSM-R2-T
Cancel all phone calls redirection for the SIM card which is inserted into GSM RELAY.
The “temperature regulation”
function of GSM-R2-T was
deactivated
GSM-R2-T was
deactivated by incoming
phone call by master
Change the parameter xRemCall
= 0 on SIM card to deactivate the function “pulse by ringing”. Then
activate the “temperature regulation” function again by SMS. E.g. “1234 TEMP25”.
The temperature from an external
temperature sensor is wrong
Too long lines to an
external temperature
sensor
The accuracy of temperature depends on a line length to an external temperature sensor (16 Ohms
means 1°C). Use thicker wires to temperature sensor.
Some parameters are missing on the
SIM card
The phone book on a SIM
card is full. (There is no
place on a SIM card for
parameters)
Delete some of contacts in the phone book on a SIM card (minimum is 60 free contacts).
