G-Systems Temperature and Negative Pressure Controller (16A)

G-Systems Temperature and Negative Pressure Controller

Controller with temperature, minimum-speed and negative-pressure settings, controlling inlet and exhaust fans. It maintains a constant temperature and pressure in the room to contain odours. Where the room has unrestricted air access, it can be used to control two exhaust fans.

Easy to use - simply set the desired temperature, speed and pressure.

Reliable - with a waterproof housing, socket covers and low voltage, making it an ideal solution for humid rooms.

The sensor has a 4-metre cable that can be extended up to 50 metres if required.

How to use:

The controller operates one or two fans - one inlet and one exhaust fan, or two exhaust fans. The exhaust fan is connected to "Fan 1", and the inlet fan to "Fan 2". Set the desired temperature value.

The "minimum speed" setting sets the minimum speed of the exhaust fan as a percentage of its maximum speed. With "off", ventilation stops when it is not needed; at any other value, it runs at the set speed.

The "under pressure" setting sets the inlet fan speed as a percentage of the exhaust fan speed. If you use this controller for 2 exhaust fans, set it to 100%; otherwise, determine the appropriate value experimentally.

As the temperature rises, the fan speeds increase smoothly and, with an increase of 2^o , reach 100%. As the temperature drops, the speeds decrease again to the level set by "minimum speed".
