Adjustable Thermostat Comes complete with a 40-wattBy using the Solar Whiz adjustable thermostat, you can control exactly when the Solar Ventilator will operate only when the temperature exceeds your preset temperature setting. This means that once your set temperature is exceeded during summer, hot air is extracted from the roof, but during winter the thermostat retains the heat, and helps to keep the house warm.
