The SPC VESTA THERMOSTAT works both in summer and winter if your controlled system is a heat pump.
*For heating systems with a gas boiler, either individual or collective, use only the heat mode; you can switch between modes from the thermostat or from the SPC IoT app control panel.
When it is in cool mode, it will serve to control the system in summer. This way, the heat pump will start working when the target temperature is higher than the measured temperature.
