Hybrid Controller Mk2
The Hybrid Controller MK2 uses a software-based technology, combined with a 5-step mechanical system for
speed control of the ventilation system. It is designed to maintain a constant temperature, and to keep the air
flow under control at all times. The presence of a heavy duty 5 step transformer makes the Hybrid Controller
MK2 the most reliable and silent controller on the market that guarantees no buzzing or humming from your
fans even at the lowest speeds. In addition, the MK2 software on the Hybrid Controller will also keep humidity in
your room under control during the dark cycle – when it matters the most!
Achieving Negative Air Pressure.
Always choose fans with a difference in airflow capacity. For example, choose a 1000m3/hr and a 2000m3/hr.
The ventilation system will now automatically create the correct negative air pressure.
Note that the smaller fan is connected to the ''FAN AIR IN'' power outlet and the larger fan to the
'' FAN AIR OUT '' power outlet.
Of course you can connect only a single fan if required. Connect a fan of no more than the total amps of the
controller to the ''FAN AIR OUT'' power outlet.
The Hybrid Controller MK2 will automatically step the fans to the appropriate speed necessary to maintain the
set temperature.
Usage:
1. Connect your fans to the sockets
2. Set the MINIMUM fan speed with dial 1 (e.g., step 1)
3. Set the desired temperature using dial 2 (e.g., 25 °C )
4. Set the MAXIMUM fan speed with dial 3 (e.g., step 5 )
5 . Place the temperature sensor in your room. Note; do not place in direct airflow or directly under a light
source.
6. Place the Light Sensor in your room, facing the light source; do not remove the cap yet! *
7. Now connect the Hybrid Controller MK2 to the mains power source.
* PRO function OFF (cap not removed)
As long as the cap is not removed, the PRO function will not be activated. Use the PRO feature only when
humidity control is critical.
* PRO function ON (cap removed)
The PRO feature ensures that extra air is refreshed at night, even if the temperature does not require more
ventilation. As soon as the sensor detects that it is dark, the fans will run 1 step faster than the current setting,
every hour for 7 minutes. The high humidity that occurs overnight will thus be removed from the room.
By just this slight increase in the speed of the fans, the temperature, especially in the cold winter months, will
not be adversely affected. Because moisture problems generally only occur at night, as soon as the light turns
on again the PRO function will turn off and the controller will run in the normal mode.
Please note that, once the PRO feature is activated, you only can disable this function by a reset. (Unplug the
mains power cord of the Hybrid Controller, place the cap back on the sensor, and then plug the mains power
cord back in.)
