Experimental Horticulture Lab User Manual for Cooling System
Included in each project are a Honeywell digital non-programmable thermostat,
a 12cm PMDC brushless fan, and a 12 V Dell power supply. All of these parts
have been wired up and the fan is mounted to the end of the module. First the
power supply must be plugged in to an outlet. This will supply power through
the thermostat, and when the threshold temperature on the thermostat is met
the thermostat will supply that power to the fan turning it on. The thermostat
is internally powered by 2 AA batteries. If the thermostat ever does not turn
on or dies, set the switch on the bottom left of the thermostat to OFF, remove
the back casing gently, and replace the batteries with new ones. We have
provided fresh AA batteries for each thermostat and should last on average
over a year. If you are not growing plants, it is recommended that you remove
the batteries from the thermostat and save the batteries for when you are
growing plants. Make sure that at any time you are removing the batteries that
the switch in the bottom left of the thermostat is set to OFF. To set the max
threshold temperature on the thermostat simply move the switch on the bottom
left of the thermostat to COOL and adjust your desired temperature using the
arrows to the right of the display screen. Once your desired temperature has
been set, place the thermistor PCB board that comes out of the thermostat into
the soil of your plants. This board has been coated with a protective film and
should not rust or decay. If the thermistor records a temperature above your
set temperature the fans will turn on until the thermistor records a
temperature lower than your threshold temperature.
