DESCRIPTION
- EC room controller in 4 versions for control of temperature, humidity, or CO2 temperature.
- Also available in a universal version for 0-10 V input via an external sensor.
TECHNICAL DESCRIPTION
EC BASIC-T Temperature version
The controller works by comparing the current room temperature with an adjustable setpoint. It controls a 0-10 V output signal with a PI algorithm in direct or reverse action, based on the setting of jumper JP1. The output signal is applied to a ventilator.
- JP1 closed 1-2: Heating (control signal increases if the actual value falls below the setpoint)
- JP1 closed 2-3 (*): Cooling (control signal increases if the actual value exceeds the setpoint)
The setpoint is adjusted by a knob in the range of 5-30°C.
Proportional band and integral time are set using rotary switch SW1:
| SW1 | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Prop. band (°C) | 0.5 | 1.0 | 1.5 | 2.0 | 2.5 | 3.0 | 3.5 | 4.0 |
| Integral time (s) | 1800 | 1700 | 1600 | 1500 | 1400 | 1300 | 1200 | 1100 |
| SW1 | 8 | 9 | A | B | C | D | E | F (*) |

| Integral time (s) | 1000 | 900 | 800 | 700 | 600 | 500 | 400 | 300 |
factory settings
The range of the voltage applied to the ventilator is defined using the MIN and MAX knobs. MIN is used to define the minimum applicable voltage to the ventilator (0-5 V), while MAX defines the maximum voltage (5-10 V). The PI controller will then operate between the relevant MIN and MAX values.
- Example 1: If the MIN value is set to the minimum position and MAX to the maximum position, the PI controller will work from 0-10 V.
- Example 2: If MIN is set to 2 V and MAX is set to 7 V, the PI controller works from 2 to 7 V.
EC BASIC-H Humidity version
TECHNICAL DESCRIPTION
The controller works by comparing the current room humidity with an adjustable setpoint. It controls a 0-10 V output signal with a proportional algorithm in direct or reverse action, based on the setting of jumper
- JP1. The output signal is applied to a ventilator.
- JP1 closed 1-2: Humidification (control signal increases if the actual value falls below the setpoint)
- JP1 closed 2-3 (*): Dehumidification (control signal increases if the actual value exceeds the setpoint)
The humidity setpoint is set using rotary switch SW1:
| SW1 | 0 (*) | 1 | 2 | 3 | 4 | 5 | 6 | 7 |

The range of the voltage applied to the ventilator is defined using the MIN and MAX trimmer. MIN trimmer is used to define the minimum applicable voltage to the ventilator (0-5 V), while MAX trimmer defines the maximum voltage (5-10 V). The P controller will then operate between the relevant MIN and MAX values.
- Example 1: If the MIN value is set to the minimum position and MAX to the maximum position, the P controller will work from 0-10 V.
- Example 2: If MIN is set to 2 V and MAX is set to 7 V, the P controller works from 2-7 V.

The controller also compares current CO2 levels with an adjustable setpoint and controls a 0..10 V proportional, secondary internal signal in direct action.
The output signal applied to the ventilator constitutes the maximum between internal signal # 1 and internal signal # 2.
The setpoint is adjusted by a knob in the range of 5-30°C.
