Overview
This device is used for ventilation control in closed-type livestock buildings.
It allows the user, according to the signal of the temperature probes, to
maintain the ambient temperature and humidity of the building on a
specified curve by controlling the operation of ventilation, heating and mist
cooling so as to meet the requirements for the growth of livestock.

FEATURES:
High-performance CPU:
MicroChip PIC18F4685, the latest product of Microchip, is used as the
main CPU of the controller. With the instruction cycle of 160ns, it’s the one
of the highest performance 8-bit Micro-controller products in the world

Control Object:
The 8-stage controller is used to control the fans, heaters and mist cooling
units. Among others, V1/V2 control the variable-speed fans, Stage 1-6
control the constant-speed fans. Stage 7 can be configured as fans or
cooling units. Stage 8 can be configured as fans cooling units or heaters.
EC-T8 Controller can also set the opening degree of the ventilation
window and curtain according to the setting of the fans.
EC-T8 controller offers two 0-10VDC outputs. It can also control the
variable-speed fan(V1,V2) with the use of EC-TY module.
Independent temperature probe:
Up to four temperature probes (three indoor and one outdoor) and one
humidity probe can be connected to the controller, which enables the
machine to obtain a more accurate reading of the average room
temperature with a faster reaction time. Access to the number of
temperature sensors can be set up.
Temperature controlling curve:
The controller can be set to automatically change the temperature and
humidity in accordance with the user’s requirements by specifying a
temperature curve with up to six different points each. The coordinates of
the curve are (days, temperature). The controller will adjust the
temperature and humidity according to the specified curve in a linear
fashion. When the last point of the curve is reached, the temperature set
point for that day is maintained until the curve is reactivated.
Minimum Ventilation Curve:
The minimum ventilation curve ensures indoor oxygen supply and proper
humidity of the room. The minimum ventilation curve can be defined by the
user and adjust the minimum ventilation of the building according to the
age of the animals.
Outside Temperature Compensation:
The minimum ventilation curve of Stage 1 fans can change automatically
according to the outside temperature. When the outside temperature
compensation option is correctly set, the opening duration of the minimum
ventilation curve reduces as the outdoor weather gets colder and the totle
cycle time of the curve remains unchanged, which effectively reduces the
decrease of the room temperature.

Humidity Compensation:
When the humidity level is too high, the cooling equipment (such as mist
cooling unit) can be turned off or the next Stage fans can be turned on.
Alarm Settings:
High/low temperature alarms and display can be defined. The defective
temperature probe can be indicated.
Cross and Tunnel ventilation:
In the livestock building, as the temperature rises, the ventilation mode
changes from cross ventilation to tunnel ventilation gradually. In the tunnel
ventilation mode, the cross ventilation fans will turn off so as to level off the
temperature difference in the room.
Special Protection Measures:
The special fan startup protection can avoid high current when fans turn
on simultaneously. If the controller is defective, the built-in minimum
ventilation ensures that catastrophic accident can be avoided.
Overload and overvoltage protection:
Fuses are installed at the input and outputs of the controller to protect its
circuitry in the case of an overload or overvoltage.
Computer network:
Within a certain area, the controllers can be connected by RS485 lines
and managed by one computer. The computer collects the real time
running data of all online controllers and can set the parameter of the
controller. The collected running date can be released through the Internet.
