With the Exo Terra 300W Electronic ON/OFF Thermostat you can create a well controlled heating system that allows you to maintain the required temperature conditions similar to those found in a desert or tropical environment.

The Thermostat will also help to prevent overheating and undercooling during hot summer days or cold winter nights.

The electronic Triac switch keeps the temperature at the desired setpoint with a much higher accuracy compared to conventional thermostats and virtually eliminates temperature swings in the terrarium.

The Exo Terra Thermostat should be set according to the needs of the animals. Thoroughly research the preferred optimum temperature range (POTR) for your specific reptile, so you can create the correct temperature gradients inside the terrarium to allow your reptiles to thermoregulate.

FEATURES

The Red LED heat indicator will light up when the heating device is ON and will shut off once the desired temperature has been reached.

The recessed dial of the thermostat will prevent accidental temperature change if the device is being handled.

Accurately controls terrarium temperatures.

Controls heating devices up to 300W

From 18°C up to 38°C

Red LED will indicate when heating device is ON

Recessed dial to prevent accidental temperature change

Waterproof remote sensor

The recessed dial of the thermostat will prevent accidental temperature change if the device is being handled. The Thermostat comes with a 3.6 foot / 110cm power-cord with grounded plug & receptacle for increased safety and to allow the use of a power outlet strip. The waterproof remote sensor can be safely used in highly moist terrariums and aquatic environments.

CAN BE USED WITH


Simply connect your Heat Mat, Heat Cable or Ceramic Heater to the Exo Terra ON/OFF Thermostat, set the preferred temperature and place the heat sensor in the desired spot.

NOTE: In combination with a non-visible light emitting heat source (like Exo Terra’s Heat Mat, Heat Cable, Ceramic Heater, Infrared Basking Spot or Night Heat Lamp), the Exo Terra 300W Dimming & Pulse Proportional Thermostat allows you to create a well-controlled 24-hour heating system that will not interrupt your animal’s normal activity cycle, while maintaining the required temperature conditions similar to those found in their natural environment.

NOTE:
When using the Exo Terra 300W Dimming & Pulse Proportional Thermostat in combination with a visible-light emitting bulb (like Exo Terra’s Intense Basking Spot, Daylight Basking Spot or Daytime Heat Lamp) to create a daytime basking area or for ambient daytime heating purposes, you need to switch the Thermostat on at sunrise and off at sunset either manually or by means of a timer, in order to avoid the bulb to emit light at night disturbing your animal’s normal activity cycle.

 

Day & Night Heating:
  • Heat Mat (PT2015/16/17/18)
  • Heat Cable (PT2011/12/13) 
  • Ceramic Heater (PT2044/45/46/47/48)

HOW TO INSTALL

INSTALLATION in Exo Terra Natural Terrariums
Follow this installation procedure to install the Exo Terra® Thermostat on any size of Exo Terra® Natural Terrarium:
  1. Unlock the top screen cover and lift it off the terrarium.
  2. Slide one of the inlet holes (located on the back of the screen top on either side) to the open position, so the wiring will fit through.
  3. Feed the wire with sensor through the first available inlet hole on the preferred side on the back of the screen cover.
  4. Position the sensor inside your terrarium, in the location where you want to reach the temperature set on the dial. This can be on top of the substrate if you are using a Heat Mat or Heat Cable, but this can also be on a branch, cave or pile of stones if you are using a Ceramic Heater to heat up a certain basking area.
  5. Place the top screen cover back on the terrarium and lock it into position.
  6. Close the remaining inlets by sliding the slider against the tubing or wires to prevent escape from feeding insects and smaller animals.
  7. Place the Exo Terra Thermostat on a solid, level surface.
  8. Connect your heating device (Heat Mat, Heat Cable, Ceramic Heater, etc.) to the receptacle of the thermostat. Controls heating devices up to 300W.

WARNING: Do not overload the Exo Terra Thermostat by connecting heat devices with outputs greater than 300W. Damage from overloading is considered misuse and is exempt from the guarantee.

The Exo Terra Thermostat should be set according to the needs of the animals. Thoroughly research the preferred optimum temperature range (POTR) for your specific reptile, so you can create the correct temperature gradients inside the terrarium to allow your reptiles to thermoregulate.


Always use a thermometer to monitor the inside temperatures of your terrarium. Adjust the Exo Terra thermostat according to the required temperature range for your pet’s environment.

To set the preferred temperature: turn the temperature dial on the backside of the thermostat, using a flathead screwdriver or other tool. A red LED will light up, to indicate that the Thermostat is powering the connected heating device, until the set temperature has been reached on the location of the sensor.

  • Red LED lights up: heating device is powered
  • Red LED turned off: heating device is no longer powered, set temperature has been reached
WARNING: Always read the complete instruction manual inside the product box.
