Setting up the Thermostat for use with
a Vitopod / Geopod / Humidity Dome
1. Connect the plug of the Vitopod/Geopod or the Heat Mat of the humidity
dome to the socket on the thermostat – use the base of your thumb to click
the plug into place and connect the earth pin (the top one) into the socket
rst. Connect the plug from the thermostat into your mains socket.
2. Feed the temperature sensor wire through one of the vents.
3. Place the temperature sensor in the Vitopod/Geopod/Humidity Dome at least
1inch (2.5cm) from the sides and base of the Vitopod. DO NOT push the
temperature sensor into soil/compost and do not have it touching the base.
4. When plugged in, the gure displayed is the current temperature registered
by the probe.
5. Press the SET button once to display the current ‘pre-set’ temperature.
6. Press and hold the SET button for 3 seconds to enter the temperature
selection mode. Press the UP or DOWN arrow buttons to adjust the
temperature. The thermostat’s LED screen shows the numbers as you cycle
through them. Press the SET button again to set the chosen temperature.
The heating LED diode illuminates when the base is in the process of heating.
When the LED diode is not lit, the base isn’t providing heat. The LED diode
turns off automatically when the base reaches the pre-set temperature.
7. Press and hold the DOWN arrow button for 3 seconds to display the
temperature in Celsius. Press and hold the UP arrow to display the
temperature in Fahrenheit.
Setting up the Thermostat for use with a heat mat
It is recommended that you DO NOT insert the temperature sensor into the soil.
1. Connect the plug of the Heat Mat to the socket on the thermostat – use the
base of your thumb to click the plug into place and connect the earth pin (the
top one) into the socket rst. Connect the plug from the thermostat into your
mains socket.
2. Place the temperature sensor above the heat mat/seedling trays.
We recommend that you DO NOT insert the temperature sensor into the soil/
compost as the probe is an ‘air sensor’ and if inserted into soil/compost it may
corrode very quickly.
3. When plugged in, the gure displayed is the current temperature registered
by the probe.
4. Press the SET button once to display the current ‘pre-set’ temperature.
5. Press and hold the SET button for 3 seconds to enter the temperature
selection mode. Press the UP or DOWN arrow buttons to adjust the
temperature. The thermostat’s LED screen shows the numbers as you cycle
through them. Press the SET button again to set the chosen temperature.
The heating LED diode illuminates when the base is in the process of heating.
When the LED diode is not lit, the base isn’t providing heat. The LED diode
turns off automatically when the base reaches the pre-set temperature.
6. Press and hold the DOWN arrow button for 3 seconds to display the
temperature in Celsius. Press and hold the UP arrow to display the
temperature in Fahrenheit.
DO NOT IMMERSE CONTROLLER IN WATER
If the probe’s temperature reaches 42°C (108°F), the automatic safety shut-off
is activated.
The majority of heated bases/heat mats are designed to reach the desired
temperature within 5 hours. Generally, you can expect a heat lift of 10°C–12°C
depending on individual use of equipment and conditions.
If it takes longer than 5 hours to reach the desired temperature, consider moving
the tray to a more insulated area or use a humidity dome if not already using.
This will conserve power and increase the mat effectiveness.
