The ne adjustment function enables you to make small changes
in temperature. It pays to use this function when the room tempe-
rature remains the same but it is too cold or too hot.
Room temperature measurement in use:
When a room sensor is in use, ne tuning directly effects the cal-
culated room temperature + 4°C.
The corrected setting for the room temperature is “Room temperature
setting + “ Fine adjustment” + “Potentiometer (TMR/SP) determined
room temperature setting change”
Room temperature measurement is not in use:
When the room sensor is not connected, ne adjustment effects
the heating curve as a parallel shift and the steepness of the curve
does not change. The effect of ne adjustment on the supply
water temperature can be seen on the bottom row.
Fine adjustment
Instructions:
Press OK in the main display.
Turn the control knob in the desired direction
and press OK to conrm.
Fine adjustment settings can also be inspected and changed in set-
tings (see p. 46).
If outdoor temperature changes effect the room temperature, the
heating curve’s settings must be changed. (see next page).
Too cold
Use the ne adjustment to raise the room temperature.
In this example the room temperature is raised 0.5 C.
Too hot
Use the ne adjustment to lower the room temperature.
In this example the room temperature is lowered 0.5 C.

Heating curve settings
The 3-point curve has automatic curve adjustment! The controller do-
es not allow descending curves or curves that are too concave.
A parallel shift can be made to the heating curve using the ne adjust-
ment function (see p. 48) The 5 point curve is taken into use in process
settings (see p. 29 and 34, how to set a 5 point curve)
The ends of the heating curve are adjusted using the minimum and
maximum limits. The supply water minimum limit setting ensures
that the pipes do not freeze. The maximum limit setting ensures that
excessively hot water that could damage structures (e.g., parquet
with oor heating) does not enter the heating system.
The basis of an even room temperature is a heating curve of the
correct shape. The correct shape depends on many factors. (the
building’s insulation, type of heat distribution, size of the network,
etc.). The supply water temperature for different outdoor temperatu-
res is set in heating curve settings. With Ouman EH-800 the heating
curve can be adjusted exactly to meet the needs of the facility from
either three or ve points. A 3 point curve is the factory setting.
Examples of 3 point curve factory settings:
1. Floor heating, damp rooms
The controller has factory set curves and settings suitable for dif-
ferent heating modes that usually do not have to be changed.
The heating curve needs to be adjusted if the room tempera-
ture does not remain even when the temperature is below ze-
ro and falling.
If the room temp. drops,
make the curve steeper
(set the bigger values
at -20 and 0).
If the room temp. rises,
make the curve less steep
(set the smaller values
at -20 and 0).
Note! Changes effect room temperature slowly
Wait at least 24 hours before readjusting settings. Especially in buil-
dings having oor heating the delays in room temperature changes
are quite long.
The supply water minimum limit setting also ensures a comfortable and good drying
temperature in the summer.

The supply water info shows which factors are effecting the supply water temperature at
the time of inspection. The starting point is the supply water temperature according to the
outdoor temperature (according to the heating curve). For example, if you see a temperature
drop in the supply water info you can determine which settings may be incorrect (e.g., mini-
mum or maximum limit settings).
According to the example in the diagram the supply water is 35.1°C. The supply water setting has
been adjusted 5,9 °C.using the ne adjustment. According to these the calculated supply water set-
ting is 41.0°C (=35.1 + 5.9).

Minimum allowed supply water temperature. A higher minimum temperature is used in damp
rooms and tiled rooms than in, e.g., rooms having a parquet oor to ensure a comfortable tem-
perature and removal of moisture in the summer.
Maximum allowed supply water temperature. The maximum limit prevents the temperature
in the heating circuit from rising too high, preventing damage to pipes and surface materials.
If, e.g., the characteristic heating curve setting is incorrect, the maximum limit prevents exces-
sively hot water from entering the network.
The length of the outdoor temperature measurement monitoring period from which the control-
ler calculates an approximate average. Supply water temperature control occurs on the basis of
the measurement of the average. The factory setting for the radiator heating delay is 2 hours and in
oor heating (0h) the delay is not used. If the temperature is below zero and falling and for a period
of time the room temperature rises too high or if the weather warms up and for a period of time the
room temperature falls too low, increase the outdoor temperature delay time. If the opposite hap-
pens, decrease the delay time.
The outdoor temp. limit at which the H1 control valve is closed. (pump stop see p. 15). The setting
is the same for control circuits H1 and H2. The summer function is inactivated when the outdoor
temp. is at least 0,5° C below the setting and the clearance delay has ended (clearance delay see p.
49) If oor heating for damp rooms is in use, the factory setting for the summer function is “not in
use”. The summer function is inactivated if the supply water freezing risk gives an alarm. This set-
ting can be set in the H2 control circuit only if ”closed” has been selected for the valve position in
summer function (see p. 49)
Floor heating anticipate attempts to minimize changes in room temp. when the outdoor temp. chan-
ges. In oor heating, the concrete slows the transfer of heat into the room. Floor heating anticipa-
te minimizes changes in room temp. when the outdoor temp. changes. If the temp. is below zero
and falling and for a period of time the room temp. falls too low or if the weather warms up and for
a period of time the room temp. rises too high, increase the outdoor temp. delay time. If the oppo-
site happens, decrease the delay time.

Control mode Explanation
EH-800 controls the supply water temperature automatically according to
the need for heating and possible time programs and home-away cont-
rol commands. Automatic control is the recommended control mode.
Continuous nominal temperature.
Continuous temperature drop
Continuous big temperature drop
The valve remains in that position until manual control has been turned off. The measured
H1 valve position appears in the controller’s display. If cascade control is in use, the control-
ler can move the H1 valve into the desired position using the actuator connected to EH-800.
The controller can also move the cascade control valve into the desired position. If casca-
de control is in use and you switch the controller to manual via a mobile phone, the % that you
give represents the combined positions of the valves. Examples: 100% = both valves complete-
ly open. 50% = the valve connected to EH-800 is closed and the cascade control valve is complete-
ly open. 30% = the valve connected to EH-800 is closed and the cascade control valve is 60% open.
The controller lets the supply water temperature drop freely to the freezing limit.
Manual mechanical Unplug the controller from the power source. The EH-800 cont-
roller also has a mechanical hand-operated lever. Press the cont-
rol knob (1) and turn the lever (2) simultaneously.
The position of the hand-operated lever indicates the position
of the valve.
None of the time programs are in
effect with forced drive.
Send a message: H1 Control modes. The controller sends a return message in which a * ap-
pears in front of the control mode in use. If you want to change the control mode, move the *
in front of the desired control mode and send the message back to the controller. The controller
will then send a return message showing that it has switched to the desired control mode.

Home/Away control (H/A)
When a home control command is received, the controller by-passes the present temperatu-
re drop command in use and switches to nominal temperature.
An away control command causes the controller to switch to temperature drop. The control-
ler switches to a big temperature drop if the week program or exception calendar controls it
to a big temperature drop.
In the no Home/Away control mode the controller is on automatic control and follows the
week program and exception calendar. If time programs have not been made, the controller
is in the nominal temperature mode.
Home
Away
No H/A control
Home/Away control Explanation
The “Home” and “Away” controls can only be used if the controller is on automatic control.
The control command can be given from the controller’s menu, from the home/away switch
connected to the controller or from a mobile phone. Regardless of from where the control
command comes, the controller’s Home/Away display is updated. The last control command
is in use. The control command affects both H1 and H2 control circuits.
Key words:
Home
Away
The Home/Away control is only in effect if the controller is on automatic control.
When you send a Home or Away message, the controller sends back an OUMAN mes-
sage showing that the HOME or AWAY control is on.
Muut ohjaukset -> Home/Away control
Example 1. The controller does not have a week program or exception calendar program:
An “Away” command causes the controller to switch to a temperature drop.
A “Home” command causes the controller to switch back to a nominal temperature mode.
Example 2. The controller has a week program:
An “Away” command causes the controller to switch from the weekly program to a temperature drop.
A “Home” command causes the controller to switch to a nominal temperature mode and then begin temperature drops
according to the weekly calendar.
Example 3. The temperature drop has been made with the exception calendar and you want to temporarily switch to a nominal
temperature.
A “Home” control causes the controller to switch to the nominal temperature mode.
An “Away” control command causes the controller to switch back to a temperature level controlled by the exception calendar.

Other controls: Relay control
The controller stops the pump when the outdoor temperature rises above the “Summer func-
tion (outdoor temp. limit)” (see p. 35). Go to H2 control circuit special settings to select whet-
her the H2 control circuit is to be actively controlled during pump summer stop or whether
the H2 control circuit valve is to be at the minimum limit (see p.49). During the period when
the pump is stopped it runs once a week during valve ushing to prevent the valve from be-
coming stuck (see p. 37). The pump runs when the controller is without operating voltage
(230V). If “ON” has been selected, the pump runs continuously and the relay is open. If “OFF”
has been selected the pump is stopped. If ”Auto” has been selected, pump runs according
to the outdoor temperature.
The controller’s device settings determines which temperature measurement controls the re-
lay and whether relay control begins when the temperature rises or falls to that setting. The
controller’s display shows you which temperature measurement information relay control
uses, the temperature measurement information and the present state of the relay. Examp-
les:
1. When the boiler temperature rises above the setting the controller switches on the char-
ging pump and collects heat into the accumulator. When the boiler temperature drops below
the setting the amount of the hysteresis, the charging pump is switched off.
2. The controller switches on an additional heat source (e.g., an electric heater), when the tem-
perature of the boiler drops below the setting and switches off the electric heater when the
temperature of the accumulator rises the amount of the hysteresis above the setting.
Pump summer stop:
Relay control according to the temperature:
Relay use Explanation
Relay control is in use if an extension unit is connected to the controller. Relay control is ta-
ken into use from the controller’s device settings. Relay control can be used to stop the pump
for the summer. or the relay can be controlled according to the temperature, temperature
difference, position of the valve or the time program. If hybrid heating has been taken into
use, the controller reserves the relay for charge pump control. Normally, the relay’s control
mode is automatic. If necessary, the relay can be force controlled ON or OFF.

Relay control
Two different temperatures are compared, e.g., the temperatures of the solar collector and ac-
cumulator. When the temperature difference is large enough, e.g., 10 °C, the solar collector’s
circulating pump is switched on. When the temperature difference drops to, e.g., 3 °C, the cir-
culating pump is switched off.
Relay control is switched on (ON) when the valve opens to the set setting. Relay control is
switched off when the valve position is at the OFF setting. The present actuator position and
relay mode can be seen from the controller’s display.
Select the energy mode according to H1 control valve’s control information.

Relay control according to the H1 Valve position:
Example: The water in the boiler is rst warmed using inexpensive energy (e.g., air-to-water heat
pump) When EH-800 has almost completely opened the control valve (e.g., 95%) the relay is activa-
ted (ON) and the oil burner receives a running permit. When the heating need decreases the control-
ler starts closing the valve. The oil burner’s running permit is inactivated when the valve has closed
to the point at which the relay switches to the OFF mode (e.g., 90%).

When any of the alarms is activated in the device, also the sum/common alarm is activated.
The common alarm does not indicate, which alarm in the device is active. When any of the
alarms is unacknowledged, the relay is active.
An example: If EH-800 is installed in a separated room, the information of the controller`s alarm can
be transmitted to the accommodation by connecting e.g. an indicator lamp or a siren to the relay.
When the controller alarms, the indicator lamp or the siren indicates the alarm.

Temperature drops lasting over a week or temperature drops that
differ from the normal week program are done with thespecial ca-
lendar. The special calendar is stronger than the week calendar.
It is easy to make a temperature drop with the special calendar,
e.g., when going on a vacation for a longer period of time. If the
controller’s pre-increase function has been taken into use, set the
time you are returning home as the end time. Select “Automatic” at
the ending time . The pre-increase ensures that a nominal tempera-
ture will been reached at the ending time (see p. 47).
The control command symbol that appears in the EH-800 controller’s
basic display automatically changes according to what is controlling
heating levels. When the control command comes from the set ti-
me program (week/24 hour clock or special calendar), a symbol of a
clock appears in the main display. The amount of temperature drop is given in settings (see p. 11).
The pre-increase function can be used when switching from a tem-
perature drop to a nominal temperature. (see p. 47)
In this example, there is a big temperature drop from 21.12.2009 to
03.01.2010 and then the controller switches to a nominal temperatu-
re mode if the week program or Home /Away control doesn’t cont-
rol the temperature drop.
A temperature drop for a certain length of time is made using the
exception calendar as follows:
Move to exception calendar and press OK. Press OK at the “Add
new” row. Press OK and set the time (date and time), for the tempe-
rature drop to begin. Press OK.
Press OK at the mode row and select the mode for the controller to
switch to at the above set time. You can select “Temperat. drop”, “
Bigger temp. drop” or “ Contin. nominal temperat.”.
Press ” Ready” to conrm exception calendar control.
The Home/Away control is only in effect if the controller is on auto-
matic control. When you send a Home or Away message, the cont-
roller sends back an OUMAN message showing that the HOME or
AWAY control is on.
