USER GUIDE

EXTERNAL CONTROL

The units can be controlled externally with digital inputs i.e from a building automation or management system. The exter-

nal commands will be updated to each of the control panels in the ventilation unit. The unit can be controlled either from

the panels or externally and the last command will stay active.

Push button for over pressure

A push button can be wired to the ventilation unit’s main board that will activate the over pressure function. During the

over pressure cycle the supply air fan speed switches to speed 3 (eco-models speed 4) and the exhaust air fan speed swit-

ches to speed 1 (eco-models speed 2). The over pressure run time is set to 15 minutes. Over pressure can be switched off

by turning it off or on the main electricity supply to the ventilation unit.

During the over pressure cycle, the fan speed

LED light flashes.

External speed control

It is possible to choose any fan speed, or to turn off fans, with external digital inputs. When the external stop is activated,

the fans can be started again either from the control panel fan button (1) or with an external digital input.

Emergency stop

On the main board there are terminals (STOP) for external digital input for an emergency stop switch. The emergency stop

will turn off the ventilation unit. It is restarted by de activating the emergency stop switch.

Cooling recovery

The rotating heat recovery wheel can be turned on and off (terminal LTOC) with an external temperature difference ther-

mostat or from a building automation system.

During the cooling recovery cycle, the heat recovery LED light flashes.

Heat recovery cannot be stopped manually from the control panel during the cooling recovery cycle.

External alarm input

An external alarm input can be connected to the main board ALARM terminals i.e from a fire detection control or heating

coil freezing protection. The unit can be restarted by de-activating the external alarm and by switching on and off main

electricity supply to the ventilation unit.

TFC

LTO

TEMP

In EC- and ECE –models it is

possible for the supply air fan to

run one speed slower than the

exhaust air fan. This is done by

connecting pins -1 (TFC) on the

main board.

It is possible to turn off the heat

recovery unit only when the outside

air temperature is above +15°C

(setpoint can be adjusted between

+10...+20°C from the main board

potentiometer)

The control panels are connected

here (in either if only one panel is

used).
