MARS HYDRO Intelligent Fan Controller User Manual

Product Overview

This manual provides instructions for the MARS HYDRO Intelligent Fan Controller, designed to manage ventilation systems based on temperature and humidity readings.

PAY ATTENTION: When using the controller for the first time, please tear off the white tape attached to the sensor probe.

Controller Modes

The controller offers several modes for managing fan operation:

• AUTO MODE: Manages fans based on temperature and humidity triggers. It supports four types of triggers: HIGH TEMP, LOW TEMP, HIGH HUMID, and LOW HUMID. The setting method for LOW TEMP, HIGH HUMID, and LOW HUMID modes is consistent with HIGH TEMP.
• ALARM SETTING: Configures alarm thresholds for temperature and humidity. It supports four alarm types: HIGH TEMP, LOW TEMP, HIGH HUMID, and LOW HUMID. The setting method for LOW TEMP, HIGH HUMID, and LOW HUMID alarms is consistent with HIGH TEMP alarms.
• TIMER MODE: Allows fans to run for a set duration. Fans operate at the speed set in ON Mode until the timer expires, after which they stop. The clock counts down if no buttons are pressed for 3 seconds. Leaving the timer mode pauses the countdown.
• ON/OFF MODE:
  • ON Mode: Fans run continuously regardless of temperature or humidity. The speed set in this mode becomes the maximum speed fans can reach in AUTO Mode.
  • OFF Mode: Fans do not run. In OFF Mode, pressing the UP or DOWN button adjusts the display's brightness.

Key Features and Operations

High Temperature Trigger (AUTO MODE)

In HIGH TEMP AUTO mode, press the UP or DOWN button to set a high temperature trigger point. Fans activate if the probe's measured temperature exceeds this set point. Activated fans gradually increase speed up to the speed set in ON Mode. When the measured temperature falls below the set point, fans slowly decrease speed until they stop. This trigger can be turned off by holding the UP and DOWN buttons simultaneously; the display will show "OFF". This trigger can activate as long as you are in AUTO Mode.

High Temperature Alarm (ALARM SETTING)

In HIGH TEMP ALARM SETTING mode, press the UP or DOWN button to set a high temperature alarm threshold. The alarm activates if the probe's measured temperature exceeds this set point. When the alarm triggers, fans will spin gradually to maximum speed, overriding other settings. This alarm can be turned off by holding the UP and DOWN buttons simultaneously; the display will show "OFF". The alarm requires the controller to be in AUTO, ON, or TIMER mode to activate.

Controller Lock

To prevent accidental changes to settings, hold the LEAF button for three or more seconds. While locked, modes cannot be switched, and settings cannot be changed. Pressing the LEAF button briefly enters an ECO display. Holding the LEAF button for three or more seconds unlocks the controller.

Alert Icons

TEMPERATURE ALARM ALERT: This icon flashes when a high or low temperature alarm that you have set has been triggered.

HUMIDITY ALARM ALERT: This icon flashes when a high or low humidity alarm that you have set has been triggered.

Control Interface and Programming

The controller features several buttons and display areas:

1. MODE BUTTON: Cycles through controller modes: ON, OFF, TIMER, AUTO (4 triggers), and ALARM (4 settings).
2. UP/DOWN BUTTON: Adjusts settings for the current mode. The UP button increases values, and the DOWN button decreases them.
3. LEAF BUTTON: Turns the display off while programs run in the background. Hold for two seconds to lock or unlock the display.
4. PROBE TEMP/HUMIDITY: Displays the current temperature/humidity measured by the sensor probe. Shows "-" if no probe is plugged in.
5. CONTROLLER MODE: Displays the current mode the controller is in. Press the MODE Button to cycle through modes.
6. ALERT ICONS: Displays alerts and statuses, including alarms and screen lock status.
7. FAN SPEED: Displays the current speed the fan is running at, or the speed it should be running at if no fans are connected.
8. SETTING: Displays the value set for the current mode. Press UP or DOWN buttons to change the value.

Fahrenheit and Celsius Conversion

To switch displayed units between Fahrenheit (°F) and Celsius (°C), set the controller to OFF Mode, then hold the UP BUTTON and DOWN BUTTON simultaneously for 3 seconds.

Temperature & Humidity Calibration

To adjust the temperature and humidity readings from the sensor probe:

1. Set the controller to OFF Mode.
2. Hold the LEAF Button and MODE BUTTON simultaneously for 5 seconds to start temperature calibration. Perform this operation again to start humidity calibration.
3. When the corresponding data flashes on the screen, press the UP/DOWN BUTTON to calibrate the temperature/humidity.
4. To save the settings, hold the LEAF Button and MODE BUTTON simultaneously for 5 seconds once more.

Display Brightness

To adjust the display brightness, set the controller to OFF Mode, then press the UP or DOWN button. Four brightness settings are available: 1, 2, 3, and A3. On setting A3, if the device is left unattended for 30 seconds, the display automatically dims its brightness back to setting 1.
