1. Place probe into the rooting area. Usually inserting down into the growing medium about 1 – 1-½ inches will provide a representative control temperature.
2. Position thermostat up an away from seedling trays and stray watering in a convenient, easy way to view location.
3. Plug Seedling Heat Mat into the thermostat.
4. Plug in thermostat power cord and set maximum desired temperature range.
5. A probe holder with suction cup is provided in case there is an application where air temperature is being controlled by a heating device.

Trouble Shooting:
Do not immerse controller or probe into water. If the thermostat remains “on” (delivering power to the heat mat) for more than 8 hours, this indicates desired temperatures are not being reached. To achieve desired temperatures the seedling heat mat may need to be placed on a more insulated surface. Another option to help hold temperatures in a seedbed area is to cover the seedling tray with a humidity dome. The thermostat has an automatic safety shut-off if probe’s temperature reaches 110°F. Do not exceed a total of 1000 watts of heating devices plugged into thermostat.

Check wire and cord annually for wear or damage.
