1. Úvod
The COMPUTHERM E400RF Wi-Fi thermostat is a wireless switching device designed for controlling heating and cooling systems. It can be managed remotely via the internet using a smartphone or tablet. This device offers easy connection to any two-wire room thermostat, gas boiler with a connection point, or any air conditioner or other electrical appliance, supporting both 24V and 230V control circuits.
The system comprises two main units: the thermostat (control unit) and the receiver unit, which directly controls the boiler or HVAC system. These units communicate wirelessly via radio frequency, eliminating the need for physical wiring between them. Both units are factory-coordinated and synchronized, each possessing a unique security code to ensure reliable operation.
