GSE temperature and minimum speed controller with 5A outlet is a speed controller for one or more exhaust fans used in indoor growing rooms.

• maintains a constant room temperature
• provides a continuous minimum speed to maintain basic air exchange
• max. current: 5.0A
• max. load: 1150W

Settings range:

• temperature: 20C° to 30C°
• min. speed: off, 20% to 100%

Technical specifications:

• dimensions W x H x D: 75x110x90mm.
• max. current: 5.0A
• max. load: 1150W
• temperature sensor with 2 m cable
• voltage: 230V, 50Hz

Installation:

• Plug the air fan into the outlet (5). Connect the temperature sensor (7), which has a 2 m cable, to the controller and choose a location for the sensor where you want to take the measurement.
• Make sure it is not directly exposed to a heat source or light, to ensure the most accurate measurement of the ambient air. Now plug the controller's plug (6) into an external outlet. The controller initializes, which can take up to 10 seconds; the green power LED (3) flashes, and the fans run at 50% power. After initialization, the green power LED (3) stays on continuously - the controller regulates from this point on.

Instructions:

1. Use the temperature setting button (1) to set the desired temperature, for example, 24°C.
2. Use the second knob to set the minimum speed (2), which should never drop during regulation; for example, we set it to 20%.
3. The minimum speed setting is the most powerful setting and always overrides the temperature setting. If you set the minimum speed setting (2) to OFF, the fan will stop running when the measured temperature is below the set temperature. The minimum speed setting (2) has a 20% startup peak to provide enough power for the fan to run at low speed.
4. The hysteresis is a fixed value of 2°C. Hysteresis is the controlled range of the fan speed. Within these 2°C, the fan speed will change from the lowest point, set by the minimum speed setting (2), to the highest control point, 100% fan speed, depending on the temperature.
5. While the temperature measured by sensor (7) is below your setting (24°C), the minimum speed regulator keeps the fan running at the minimum speed setting (20%). As the temperature rises above 24°C, the temperature LED (4) turns on and the fan speed starts to increase based on the temperature over the next 2°C, up to 100% when it reaches 26°C.
6. Small fans can be adjusted from 0-100%, but with higher power consumption (large fans), the controller operates in semi-variable mode and will automatically switch to 100%, without variable control. The controller stays on until the temperature drops.
7. Warning! Setting a high minimum speed with large fans will cause them to run at 100% due to internal overheating protection! Lower the minimum speed!

• max. current: 10.0A
• max. load: 2300W
• temperature sensor with 4m. cable
• voltage: 230V, 50Hz

Instructions:

1. Use the temperature setting knob to set the desired temperature, for example 24°C.
2. Use the second knob to set the minimum speed, which should never drop during regulation; for example, we set this to 20%.
3. The minimum speed setting is the strongest setting and always overrides the temperature setting. If you set the minimum speed setting to OFF, the fan will stop running when the measured temperature is below the set temperature. The minimum speed setting has a 20% startup boost to provide enough power for the fan to run at low speed.
4. The hysteresis is a fixed value of 2°C. Hysteresis is the controlled range of fan speed. Within these 2°C, the fan speed changes from the lowest point, set by the minimum speed setting, to the highest control point, 100% fan speed, depending on the temperature.
5. As long as the temperature measured by the sensor is below your setting (24°C), the minimum speed regulator keeps the fan running at the minimum speed setting (20%). When the temperature rises above 24°C, the temperature LED turns on and the fan speed starts increasing based on the temperature over the next 2°C, up to 100% at 26°C.
6. Small fans can be adjusted from 0-100%, but with higher power consumption (large fans), the controller operates in semi-variable mode and automatically switches to 100% without variable control. The controller remains on until the temperature drops.
7. Warning! Setting a high minimum speed with large fans will cause it to run at 100% due to the internal overheating protection! Reduce the minimum speed!

Choosing a climate controller

Consider the load type and control method. An AC fan with adjustable voltage and an EC fan with a signal input require different control methods. Follow the limitations of the specific model.

Step-down transformer that lets you control fans without the low-frequency noise at low speed.

The six control settings help you better control the exhaust fan according to the temperature and humidity settings you have selected.

The four buttons let you set the temperature, temperature hysteresis, humidity and humidity hysteresis.
Using the built-in jumper - J1 (in the box), you can choose whether the fan continues running at minimum speed or stops when the desired temperature and humidity are reached. When J1 is closed, ventilation continues at minimum speed. When it is open, the fan stops completely.

It comes with a 4m cable with a temperature and humidity sensor, an exhaust fan outlet and a waterproof enclosure.

T-Nano can be used to facilitate connection to another TechGrow controller and display the readings from connected CO₂, RH, and temperature sensors (provided it is connected to the TechGrow S-4 sensors).
To set the desired CO₂ concentration or hysteresis, use the two rotary knobs and leave the rest to the controller. The LEDs indicate when CO₂ is being dispensed, whether the climate is stable, and whether the relay is off, for example, during night mode.
T-Nano is fully compatible with many TechGrow products. We recommend using the TechGrow S-ECO sensor with this controller.
