INFORMATION ABOUT GENERAL SETTINGS
If the room temperature deviates from its set value, the room compensation
function changes the supply air temperature. E.g., if the room compensation is 3
and the room temperature is 1,5°C below the set value, the controller raises the
supply air temperature 4,5°C (3x1,5°C = 4,5°C) above the room setting. Room
compensation is doubled during the prewarming period.
Room I-control changes the supply temperature by the ”room temperature
deviation x room compensation ratio” during I-time.
The maximum effect of room I-control on the supply temperature is limited to the
temperature set here. I-control is not in use when the setting is at 0.

Ouman-105 has two types of settings:
a) user level settings that the user can adjust (p. 9)
b) maintenance mode settings that the maintenance person may have to adjust
Original factory settings are restored in special maintenance (p. 46)
General settings and control settings are in the maintenance level.

The controller gives a freezing risk alarm and shuts down the supply air unit if the
radiator return water temperature drops below the ”Freeze risk” setting. Attention!
If the outdoor temperature is above +7°C and the freezing risk set value is below
20°C, the controller uses a freezing risk set value of +4°C. (The cut off point during
a trial run is above the set value of + 20°C.)
The number of degrees that ”StartIncrease” raises the controller determined supply
air temperature during the AH unit start-up. The effect of the start-up function
disappears at a rate of 1°C/min. The start-up function cannot raise the controller
determined supply air temperature above 25 °C.
The length of the start function period during which controls cannot be changed.
The time after which the controller can lower the temperature by moving from one
control sequence to the next. (e.g., the heating valve must be closed during the
sequence delay before the HRU output can be decreased).
Night ventilation hysteresis shows how many degrees below the room temperature
the outdoor temperature must be for night ventilation to start up. (0 = night
ventilation is not in use). Night ventilation starts up when the room temperature is
at the room temperature set value + 1,5 °C and it stops at the room temperature set
value. Night ventilation is allowed during the set time period.

Control-specific settings can be
found under the control menu in question.
They can be accessed directly from general
settings by pressing the group select button.
Room temperature slow down: the time period from which the average room temp.
is calculated, which is used as the room temperature in room temperature control.
Fire risk alarm limit. The function is not in use when the setting is at 0. If the supply/
exhaust air temperature exceeds the fire risk setting the controller shuts down the
AH unit and gives an alarm.
