6.4.3 Sending SMS if there is a fault on the installation
A modem enables the controller to send an error message to a mobile
phone. As soon as a fault is registered in the device status register of the
controller, an SMS message is sent. This requires modem access from a
provider (SMSC = Short Message Service Center) which accepts SMS
messages in TAP protocol. The message on the display of the mobile phone
will then read something like this:
'Heating controller EQJW 145/device status: [XXXX]/Note: 0 = no error. >0 =
error has occurred'
The value shown for the device status corresponds to the value of SERVice
parameter SP02. The error that has occurred is stored in this value in
encoded form (see Section 7.1.2). The SMS Center usually sends the date,
time and sender's telephone number for this message.
