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
RJ45 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

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.
