DirectionsProgramming the Control Unit Upon plugging in your new Hygrotherm Humidity and Temperature control system for the first time, the digital display will illuminate and show all of the symbols for a brief moment before showing the default factory settings. After programming the control unit, the new settings will be stored in the controller’s memory. In the event of a power failure, or if the unit becomes unplugged, the programmed setting will resume once power is restored. Wait until after the unit has been programmed before plugging in heating devices, cooling devices, or humidifiers. A. Programming the Temperature Setting: The Thermostat functions of your Hygrotherm will turn heating or cooling devices on and off the maintain the optimum temperature in your terrarium. The temperature can be set in either Fahrenheit or Celsius mode. Perform the following steps to program the temperature setting of your controller 1. The temperature control range is 50°F to 122°F 2. Press and release the orange Mode button to cycle between the three main modes. Each time the Mode button is pressed, the next setting will appear. Continue pressing the Mode button until either °C or °F shows next to the larger set of numbers on the left side of the display above the word ACTUAL. 3.

Press the SET button once to increase the setting one percent. Press and hold button to increase by several percentage points. If you pass the desired setting, press and hold the SET button to cycle through the numbers again. The controller will automatically return to the normal display about 3 seconds after the relative humidity is set, and the programmed humidity setting will appear above the word PROGRAM. 4. The humidity program is now set and can be changed at any time by pressing the Set button while in the appropriate mode. C. Additional Programming Features: • Heat/Cool Mode (F01) • Nighttime Temperature Drop (F02) • Temperature Alarm Setting (F03) • Humidity Alarm Setting (F04) To enter the programming mode for the above features, press and hold the mode button while in °C or °F mode until F01 appears on the left side of the display. If the Mode button is pressed while in °F mode, the temperature drop and alarm settings will be programmed in °F. If the mode button is pressed while in °C mode, the temperature drop and alarm settings will be programmed in °C . Press and release the mode button to cycle through the four available features. The controller will automatically exit the programming mode after 10 seconds if o buttons are pressed, or after cycling through all four features. Heat/Cool Mode: In Heat mode, the controller will turn heating devices on when the actual temperature in your terrarium drops below the programmed temperature setting. In COOL mode, the controller will turn on a cooling device when the temperature in your terrarium rises above the programmed temperature setting. To switch between heat and cool mode, press and hold the mode button until F01 appears, then release the mode button. Press the set button to switch between modes. When cool mode is selected, the numbers 00 and the word cool will appear on the display. When heat mode is selected, the numbers 01 and word that will appears on the display. Nighttime Temperature Drop: Your controller can be programmed to allow for a nighttime temperature drop to simulate natural conditions, stimulate breeding behavior, and save energy. To program a drop in nighttime temperature, press and hold the mode button until F01 appears, the release. Quickly press and release the mode button again and F02 will appear on the display along with the symbol. Press the set button to program the number of degrees that the temperature will drop at night. When the setting is 00 the temperature drop feature is disabled. Alarm Settings: When programmed, the alarm functions will alert you when the temperature or humidity in the terrarium is above or below the programmed settings. When the alarm is trigger, the LCD display will flash, along with the letters TEM or HUM to indicate if the alarm is for temperature or humidity. Temperature Alarm: Enter programming function by pressing and holding the mode button until F01 appears, then release. Press and release the mode button two times until F03 appears on the display, along with the symbol and TEM shown above the symbol. Press the set button to program the temperature change that will trigger the alarm. When the temperature rises above or falls below the programmed temperature by the set number of degrees, the alarm will activate causing the controller screen to flash (i.e., if the temperature setting of the Hygrotherm is 85° F, and the Temperature Alarm setting is 10, the alarm will be activated if the temperature rises above 95°F). When the alarm is set to 00 it is disabled. Humidity Alarm: Enter the programming mode just as you did when programming the Temperature Alarm. Press the mode button until F04 appears on the display, along with the symbol and HUM shown above the bell symbol. Press the set button to program the humidity alarm just as you did for the temperature alarm. When the alarm is set to 00 it is disabled. Installing the Control Unit: After programming is complete, the unit can then be installed. Follow the steps below to complete the installation of your Hygrotherm humidity and temperature control system. 1. Set up terrarium: Make sure that your terrarium is completely set-up and that the heater and humidifier are in place. 2. Install 2-in-1 remote temperature/humidity sensor: Before plugging in the heating/cooling device and the humidifier, place the remote sensor in the desired location inside the terrarium. The sensor can be attached to the inside walls of your terrarium using double-sided tape or Velcro hook-and-loop faster. Wherever the sensor is placed is where the Hygrotherm will be measuring the temperature and humidity 3. Mount the control unit: Place the control unit in the desired location outside of your terrarium. Do not place the control unit inside the terrarium as the higher temperatures and humidity levels can have adverse effects and cause eventual failure. If you are using the Nighttime temperature drop feature, be sure that the photocell on the control unit is not blocked, and that it is in a location that will sense when it’s light or dark. 4. Plug in heating/cooling device and humidifier: Finally, plug in the heating device to the socket labeled temperature. Plug the humidifier into the socket labeled Humidity. Check to make sure that your heating/cooling device and humidifier are switched on. The installation of your Hygrotherm humidity and temperature control system is now complete. Important Notes: • Do not use to control mercury vapor UVB lamps, compact fluorescent lamps, or rock heater. • Heat: make sure that your heating device has the ability to hat your terrarium to the desired temperature. If your terrarium does not reach the desire temperature, you may need to replace the heating device with one of higher wattage. • Humidity: The relative humidity level in your terrarium can change rapidly depending on the amount of ventilation in your terrarium. Terrariums made of scree, or with large screen covers, may have a difficult time maintaining higher humidity levels. Covering portions of the screen with a suitable material may help to hold the humidity in your terrarium. Be sure not to block UVB lamps or place flammable material close to the heating devices. • Default Settings: To restore the default settings, press and hold the mode and set buttons at the same time for about 3 seconds. Note: this will erase all of your programmed settings. Error Message: In the event that the temperature or relative humidity exceeds the sensor’s limits, an error code will shoe on the display indicated by the letter E followed by a number. If an error code appears, check to make sure that our heater has not malfunctioned causing extreme temperatures. Also check to make sure that your humidifier is functioning properly and that the sensor is not submerged in water or covered with condensation. When the conditions are corrected that caused the error message to appear, the control unit should resume its normal display. If the error code continues to remain under normal temperature and humidity conditions, contact Zoo Med’s customer service department.

If this item was humidity resistant and had better quality parts, it would be perfect. I realize that under normal use (reptiles, terrarium), where most of the unit is outside the monitored area, it probably would've lasted longer. However, I've seen other people using it in their greenhouses and have no problems. Bummed that it didn't work for mine...
The design of this product has been sufficiently thought out, though there could be a few minor improvements. One notable improvement would be to the LCD screen, which is uncharacteristically flimsy. Another feature that would be nice is if it turned off the heat (instead of just sounding an alarm) if the upper limit has been reached.
All cables, switches and boxes are ruggedly built (with the above mentioned exception). I am so pleased with this product, I am likely to buy another one in the next month.
To summarize: great product for the price; rugged design; room for minor improvements.
Summing up, this is a good product if you don't have any extreme humidity needs.
