Room controller
18/11/2015 Rev. 3
EC BASIC-T Temperature version
TECHNICAL DESCRIPTION
The controller works by comparing the current room temperature with
an adjustable setpoint. It controls a 0-10 V output signal with a PI al-
gorithm 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 knob in the range 5-30°C.
Proportional band and integral time are set using rotary switch SW1:

The range of the voltage applied to the ventilator is dened using the
MIN and MAX knobs. MIN is used to dene the minimum applicable
voltage to the ventilator (0-5 V), while MAX denes the maximum volt-
age (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-CO2/T Temperature + CO
2
version
TECHNICAL DESCRIPTION
The controller works by comparing the input signal with an adjustable
setpoint. It controls a 0-10 V internal signal with a PI algorithm in direct
or reverse action, based on the setting of jumper JP1.
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 controller also compares current CO
2
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 knob in the range 5-30°C.
The temperature proportional band and integral time are set using
rotary switch SW1:

The range of the voltage applied to the ventilator is dened using the
MIN and MAX trimmer. MIN trimmer is used to dene the minimum ap-
plicable voltage to the ventilator (0-5 V), while MAX trimmer denes 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 controller will work from 0-10 V.
Example 2: If MIN is set to 2 V and MAX is set to 7 V, the controller
works from 2-7 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 proportion-
al 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: Humidication (control signal increases if the
actual value falls below the setpoint)
JP1 closed 2-3 (*): Dehumidication (control signal increases if the
actual value exceeds the setpoint)
The humidity setpoint is set using rotary switch SW1:

The range of the voltage applied to the ventilator is dened using the
MIN and MAX trimmer. MIN trimmer is used to dene the minimum ap-
plicable voltage to the ventilator (0-5 V), while MAX trimmer denes 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.
