The GSM module is designed for remote control of THERM EL electric boilers using short text messages - SMS. It enables to execute almost all user settings remotely. It also allows for reporting operating and malfunction information. It is ideally combined with an interior temperature sensor (CT02 - 43556) without using the combination with room thermostats or regulators.

The module cooperates with the automatics of the REK electric boiler, with software 06.6 and higher. The module can only be used for a separate boiler, it is not possible to control a boiler cascade with the module. The module is designed for use in recreational cottages and other irregularly visited objects. You can reach thermal comfort before your arrival using your mobile phone.
