Two Thermostats For the Price of One!!
This thermostat can be set to control a heating device or a cooling device.
To control a cooling device (or fan), set the unit to cool/fan, and the desired maximum temperature for the growing environment. Once the temperature in the environment goes above the set temperature, the fan is switched on. When the temperature comes back under the set temperature again, the fan is automatically switched off.
To control a heater or heat pad, set the unit to warm/heater, and the desired minimum temperature. Once the temperature goes below the set temperature, the heater (or heat pad) is switched on. When the temperature is above the set temperature the unit is switched off again.
The stainless steel temperature sensor has a 1 metre lead. It should be placed away from the heating or cooling device being controlled, to allow for an accurate room reading.
