Chapter 6  Starting and stopping the unit 

6.1 Start conditions 

The unit will be started and will run when any one of the following conditions is met:  

1.

 

Timer output for normal speed or timer output for reduced speed is ON  

2.

 

The unit is started manually using the Corrigo front panel or via E3-DSP 

3.

 

Digital input for extended running is activated 

4.

 

Support control is activated and the present  room temperature is higher/lower than the 
preset starting value (Support heating/cooling)  

5.

 

Demand controlled ventilation is activated and the value at the CO2 sensor is higher than 
the preset start condition. 

6.

 

Recirculation control has been configured and the conditions for recirculation control are 
fulfilled. 

Possibility to block automatic restart at power-up 

The function ”Automatic restart at power-up” makes it possible to block automatic restart of the unit 
at power-up. At power-up, the B-alarm ”Restart blocked after power on” is generated. Once this 
alarm has been acknowledged, the unit will start. 

6.2 Stop conditions 

The unit will be stopped when any of the following conditions are met: 

1.

 

Timer output for normal speed or timer output for reduced speed are OFF, and the signal 
for extended running is OFF.  

2.

 

Activated frost protection alarm. The unit will restart on resetting of the alarm.  

3.

 

Activated fire detector if the function has been configured. The unit will restart on resetting 
of the alarm. 

4.

 

If the unit has electric heating and the supply fan flow switch alarm or the high temperature 
limit alarm is activated. 

5.

 

Activation of external switch. 

6.

 

The unit is stopped manually using the Corrigo front panel or E3-DSP. 

7.

 

Support control is activated and the present room temperature is higher/lower than the pre-
set stop value (support heating/cooling)  

8.

 

Demand controlled ventilation is activated and the value at the CO

2

 sensor falls below the 

pre-set start condition less the set differential. 

9.

 

Recirculation control is active and the conditions for recirculation control are no longer 
fulfilled. 

10.

 

At an activated alarm configured with the extra function of stopping the unit on activation. 
The unit will restart on resetting of the alarm.
