The degree of room compensation, the
compensation ratio, can be adjusted with
the COMP knob.
If the room temperature deviates from
the TMR/P set value, the TMR/P adjusts
the outgoing water temperature by a
ratio of the deviation set with the Comp
knob. These examples assume the
outdoor sensor is connected.
You can temporarily by-pass the timer program as follows:
Press and hold until the desired state is displayed.
Repeating this procedure will change the state. The next
programmed time will switch the forced control state off.
If you wish to permanently use forced control, press
again until the display shows .

OUMAN can be equipped with a timer
that drops the room temperature for
desired periods (e.g., at night or on
weekends). The timer is easy to install
later.
Set the drop in the
temperature of the outgoing
water with this knob. The
numbers indicate the number
of degrees the temperature will be
dropped. General guide: a 4°C drop in the
water temperature corresponds to a 1°C drop in the
room temperature.
NOTE! If the room compensation unit TMR/P is in use,
double the temperature drop setting. This will take into
account the compensation effect of the TMR/P.

Select the desired room temperature with the TMR/P
knob. 21°C is in the middle. Each step of the scale equals
1°C. If the room temperature deviates from the set
temperature, the TMR/P automatically adjusts the
outgoing water temperature.
Example 1.
The COMP knob is in position 4. If the room
temperature drops 1,5°C, the TMR/P will raise the
outgoing water temperature by 4 x 1,5 = 6°C.
Example 2.
The COMP knob is in position 2. If the room
temperature rises 4°C, the TMR/P will lower the
outgoing water temperature by 2 x 4 = 8°C.
ONLY ROOM COMPENSATION
OUMAN can be connected as a room-controlled outgoing
water controller. (Disconnect the outdoor sensor.) Set
the room temperature with the TMR/P knob. If the delay
before the radiator temperature reacts to a change in
room temperature is too long, increase the COMP ratio.

The OUMAN EH 80 can be equipped with an optional room
compensation unit, TMR/P. It improves temperature control
in special conditions such as:
* windy weather (the house tends to get cooler)
* the house is warmed by
a fireplace, brick oven, etc.
* the house has large
windows on the south side,
and the house gets warm
on sunny spring days
regardless of cold weather.
Install the TMR/P in a
central place in the house.
