This thermostat has a watertight enclosure making them an excellent option for wet environments. The two stage thermostat can be used to automatically open motorized louvers before cutting on an exhaust fan(s), stage multiple fan or heater systems, or operate multiple speed exhaust fans that do not already have a built-in control. Wiring required.
- Wide temperature range: 30° to 110° F
- Fixed 3 degree temperature differential between stages
- Can be used with millivolt, 12, 24 and 120 volt appliances
- Can handle 15 full load amps @120V
- Can be wired for heating or cooling
- Waterproof NEMA 4X enclosure
- Two SPDT switches
What is a Differential?
placement in a greenhouse: To get the desired temperature,
thermostats should be located at plant height near the center of the
greenhouse where they are not influenced by drafts or the temperature of an exterior wall. It
is best if both heating and cooling thermostats are located together and
protected from direct contact with sunlight and water. One simple way to
accomplish this would be to mount the thermostat(s) to a piece of wood (or other nonconductive material)
with a top on it like in the picture to the left. Wood should be painted
white to shade it from the sun.|
The difference between on and off setpoints on a control. For temperature, it is the difference in degrees between the thermostat's on and off setting. If you set a heating thermostat with a 3 degree differential to 71°, it will supply power at any temperature below 71° and cut off at 74° (3 degrees above the setpoint). A cooling thermostat would cut on above 71° and off at 68°.
