Pymeter Digital Temperature Controller Heat Mat Dual Thermostat Outlet Heating Cooling for Homebrew Reptile Aquarium Greenhouse Heater

Main Features Designed with dual outlets, just plug & play Dual relays, able to control both heating and cooling device separately or meanwhile Dual waterproof probes, turn device on and off at desired temperature, very easy and flexible to use Celsius or Fahrenheit Read-out Dual LED display, read temperature from 2 probes High and Low Temperature Alarm; Differential Temperature Alarm Power-on Delay to protect output device from excessive on/off toggling Temperature Calibration Settings are retained even when power off ?Specification Temperature Range: -50~99°C / -58~210°F Temperature Resolution: 0.1 °C / 0.1°F Temperature Accuracy: ±1°C / ±1°F Controller Dimension: 210x55x40 mm Input Power: 85~250VAC, 50/60Hz Output Power: 85~250VAC, MAX 10A Buzzer Alarm: High and Low Temperature; Temperature Difference Sensor Cable: NTC Sensor x 2; 2m/6.56ft Input Power Cord: 1.35m / 4.5ft Main Functions: Heating Mode: if ON Temperature < OFF Temperature, it is on Heating Mode, socket1(2) power on when current Temperature <= ON Temperature, power off when current Temperature >= OFF Temperature;For example: set socket1 ON Temperature as 20°C, OFF Temperature as 30°C, socket1 will power on when current temperature <= 20°C, and power off when current temperature reaches 30°C. Cooling Mode: if ON Temperature > OFF Temperature, it is on Cooling Mode, socket1(2) power on when current Temperature >= ON Temperature, power off when current Temperature <= OFF Temperature;For example: set socket2 ON Temperature as 35°C, OFF Temperature as 25°C, socket2 will power on when current temperature >= 35°C, and power off when current temperature reaches 25°C.
