GSM module
III.7.
NOTE:
Controlling of this type is possible after purchasing and connecting, to
the controller, the additional control module ST-65 which is not attached to the
regulator as a standard feature.
The GSM module is an optional device cooperating with the boiler
controller, enabling remote control of the boiler operation with the use of a
mobile phone. The User is notified with a text message on each alert of the
boiler controller, and by sending an appropriate text message at any time, he
or she receives a return message with the information on the current
temperature of all sensors. After entering an authentication code it is also
possible to remotely change the set temperatures.
The GSM module can also operate independently from the boiler
controller. It has two inputs with temperature sensors, single contact input for
use in any configuration (detecting short circuit/opening of contacts) and one
controlled output (e.g. possibility to connect additional contactor to control any
electrical circuit).
When any temperature sensor reaches the preset deactivation
temperature, maximum or minimum, the module will automatically send a text
message with such information. It is similar in the case of a short-circuit or
opening of contact input, which may be used e.g. for simple protection of
property.
If ST-450 controller is equipped with an additional GSM module, in order to
activate this device, it is required to start the activated option (MENU> Installer
menu> GSM module> Activated).
