AVT557 A +

The device is designed on a microcontroller thanks to which the thermostat provides a large possibility of modifying the control parameters. The temperature monitoring range covers 0-99 ° C, which goes beyond the requirements of typical thermostats and expands the range of potential users. The possibility of adjusting the hysteresis accuracy prevents too frequent switching of the executive relay and, on the other hand, the uneconomical operation of the system.
The big advantage is the possibility of remote (via telephone) thermostat control. All system messages are forwarded to the user in the form of voice information. Access to the thermostat settings is protected by a password - this eliminates the possibility of unauthorized changes to the settings.

The device is recommended for all owners of recreational houses who want to comfortably and economically control the heating of their estates
