4. Commissioning

Important

Only a qualified electrician may make the 
electrical connections.

!

!

3.3 Electric and control cables

• Install the SET-connection unit in an appropriate

 

position in the vicinity of the sensor and actuator.

 

Connect the 

RJ

45 cables (2 pcs.) supplied with

 

the 

SET unit to the specified connections on the

 

ventilation unit.

• Install the supplied temperature sensor in the outdoor

 

air duct, before the air heater/cooler seen from the

 

direction of flow.

• Connect the sensor to the SET module’s free Sensor connection.
• Connect the heating medium pump’s power supply

 

to 

the SET-connection unit’s other relay output ac-
cording to the function diagram.

• Install any actuators according to the manufacturer’s

 

instructions and connect the control cable to the

 

SET 

connection unit’s relay outputs according to the

 

function diagram. 

NOTE!

 If the SET module is used for 230 VAC control, 

the module must be installed, according to the electrical 
safety directives, in a separate enclosure. 

NOTE!

 Make sure that the strain relief is arranged for the 

connections according to the electrical safety directives.

Commissioning the air heater/cooler is performed with 
a Smart control panel.

Commissioning of the air heater/cooler

 

Select operation of the unit by highlighting the menu 
item 

External after heater.

Limit value (heating)

 

Select the required start temperature for external pre-
heating. When the outdoor temperature (transferred 
outside temperature) measured before the air heater/
cooler drops below the limit value, the relays in the SET 
unit selected for the heat medium pump are activated. 
The operating signal is received from the relay output, for 
example, the heat medium pump and/or solenoid valve. 

Limit value (cooling)

 

Select the required start temperature for external precool-
ing. When the outdoor temperature (transferred outside 
temperature) measured before the air heater/cooler rises 
above the limit value, the relays in the SET unit selected 
for the heat medium pump are activated. The operating 
signal is received from the relay output, for example, the 
heat medium pump and/or solenoid valve. 

Select the functions for the temperature sensors used 
and fine adjust the measurements if necessary from the 

Sensor/Control 

menu.

Outdoor air sensor

 

Select the SET sensor input (T6–T9) to which outdoor air 
sensor is connected: 

SET T6 -T9

” = SET-connection unit’s Sensor inputs. 

“Internal” = The unit’s internal outdoor air temperature 
sensor.

Relay control functions

 

Select the heat medium pump function for the SET-
connection unit’s relays. 

SET Relay 1 / SET Relay 2 = 

Heat medium pump.
