Installation; Which Sensors Can Be Connected To The Humi Heavy; Connecting Additional Sensors Or Other Devices; Automatic Functions Of The Techgrow Humi Heavy - TechGrow Humi Heavy Manual

1. Installation

1. Mount the sensor on the wall, close to the
humidifier/dehumidifier, but with a minimum
distance of 150 cm. The sensor must be mounted at
a height of +/- 1 meter above the floor. Do not
place the sensor in the direct airflow of fans as this
can influence the measurements (sensor NOT
included).
2. Also mount the TechGrow Humi Heavy on the wall
with the supplied mounting kit.
3. Connect the sensor to the bottom of the Humi
Heavy with the supplied (UTP) cable(s).
4. Connect the plug of the humidifier and/or
dehumidifier to the socket of the Humi Heavy.
5. Plug the plug of the Humi Heavy into a 230V/110V
socket.
6. Ready!
2. Which sensors can be connected to
the Humi Heavy?
The minimum sensor required is a Temp/RH Sensor.
3. Connecting additional sensors or
other devices
The Humi Heavy can receive the values from connected
CO , humidity and temperature sensors and send them
2
to another controller.
The Humi Heavy can only display the RH and Temp
values.
The Humi Heavy also registers the Min/Max values of
the RH.
ATTENTION: NEVER connect two sensors of the
same type to your controller! For example: a S-4
sensor and a Temp/RH sensor must not be
connected at the same time.
4. Automatic functions of the
Techgrow Humi Heavy
1. If no sensor is connected to the Humi Heavy, this
will be shown on the display as RH ---% SENSOR!
2. Backlight turns off automatically after 30 seconds,
and switches on again only when you press or turn
the Push-and-Turn-Knob (PTK).

5. Operation of the Humi Heavy

If the relative humidity in the room falls outside the
range (setpoint +/- hysteresis), the humidifier/
dehumidifier is switched on. This depends on the set
functionality (humidifying or dehumidifying).
Example
The desired humidity level is "set" at 60%. The "hys" is set
to 2%. The current humidity level in the room is 62%;
that is 2% higher than the desired humidity level, so the
humidifier is off. All LED lights are off.
Humidification The air humidity is slowly decreasing to
60%: there is no action. Only when the value drops below
the desired humidity level ("set") minus the hysteresis
(2%), the humidifier will be switched on. That is below
60% - 3% = 57%. The humidifier switches on and the red
"humidify" light comes on. Now, the air humidity rises,
and if the value has risen above 60%, the humidifier is
switched off again. The red "humidify" light goes off.
Dehumidification The air humidity is now slowly rising
to 63%: there is no action. Only when the value rises
above the desired humidity level ("set") plus the
hysteresis (2%), the dehumidifier will be switched on.
That is above 60% + 3% = 63%. The dehumidifier
switches on and the red "dehumidify" light comes on.
Now, the air humidity drops. If the value drops below
60%, the dehumidifier is switched off again. The red
"dehumidify" light goes off.

6. Meaning led

Left LED lights red: socket is switched on.
•
Right LED lights green when the climate is stable.
•
Both LEDs off: socket switches off.

7. Operating and adjusting the Humi
Heavy
You can control all settings with the Push-and Turn-
Knob (PTK). By pressing the PTK you enter the main
menu.
RH 46% Hi / Lo 26 °C
Set 40% Hys 3% / Min 33% Max 55%
On the bottom line the set values will alternate with the
Min/Max value of the RH.
To reset the Min/Max value, press the PTK for 5
seconds.
