Intelligent heating controller for your home
Your level of comfort increases when room temperatures stay at an even level even though
outdoor temperatures change. You conserve energy when water entering the heating network is just the right temperature to maintain an optimal room temperature. The smart
controller now takes even better account of differences in heating modes and structures.
OUMAN OY has over 20 years of experience as a leading domestic manufacturer of heating controllers. Ouman is easy to use and dependable, and from the beginning, main reasons for its success. The Ouman EH-80 heating controller was a marketing success, and is
used in over 100 000 Finnish homes. Now we are displaying a new-generation controller,
EH-800, which meets todays demands. Its remote use and ability to expand also make it a
safe choice for the future.
EH-800 controls and monitors for you. It is also environment friendly because it
consumes less energy.
Conserve energy!
An even room temperature lessens
energy consumption. One degree
in room temperature is equivalent
to 5% in energy consumption.

EH-800 automatically controls the temperature of the water entering the heating network. The heating need changes according to
the outdoor temperature.
Boiler/

Heating
network
As the outdoor temperature gets colder, the controller lets just
enough heat into the network to keep the room temperature at an
even level.
Easily and quickly installed
EH-800 is compatible with the most commonly used boiler and
accumulator valves. Installation sets for Esbe VRG and VRB valves
can be obtained as optional equipment. You can install it yourself without any special tools.
A large and clear display
The easy-to-use display is large
and distinct and all necessary information can be seen at a glance.
Recent measurement history
can also be seen as a graphic display; in the morning you can check
how a temperature drop occurred
or how cold it got outdoors during
the night.
Detach the control knob from the valve and put the mounting kit into place. Press EH-800 into place,
connect the sensors, plug it in and the unit is ready to use!
Central water heating houses
Easy to take into use
EH-800 contains preset basic settings for different types of heating. The
first time you turn on the controller just select from the display the control mode of your house and it is ready to use.
Ouman EH-800 is suitable for every house with central water heating whatever the source of heat;
oil, the sun, wood, pellets, district
heat, electricity or thermal heat.
The controller has settings for the following heating modes:
• Floor heating
- normal rooms
- damp rooms (also summertime heating)
• Radiator heating
- normal curve
- steeper curve (homes that need warmer water
in the heating network)
• Concrete floor drying function during construction
(controlled increase in temperature)
• Constant temperature (e.g., accumulator start-up/
charging or boiler circulating temperature control)
Diverse time programs
Use the controller’s week/24 hour clock to program energy conserving temperature drops coinciding with your
own weekly rhythm.
Dynamic curve
The ratio between the outdoor temperature and the
temperature of the water entering the heating system
is determined and displayed using the curve. When the
outdoor temperature drops, warmer water is let into
the heating system and the opposite happens when
the outdoor temperature rises. After adjusting settings on the curve, the change immediately appears
on the curve on the controller’s display.
Ingeniously simple
The too warm/cold function is a
truly simple way to finely adjust
heating. Turn the control knob in
the desired direction to either increase or decrease heat. The controller makes the necessary setting changes taking into account
the room sensor if it is connected.

Put your boiler room on the network!
The controller can be used either with a home network or an internet web browser (not EH-800B).
Connecting to an
intranet or internet
All you need is an ethernet cable to connect to an intranet. You
can easily enter network settings
and user names in the controller’s
menu.
We recommend using information
secure Ouman 3G or Ouman Access internet packages when con-
necting the controller to a public
network. This ensures that traffic
is shielded and gives you the option of a name service for administration of a changing IP-address.
We recommend to use Internet Explorer, Mozilla Firefox or Google
Chrome.
Communication via a mobile phone
It is possible to communicate with the controller via a GSM phone if a
GSM modem has been connected to the controller. (optional equipment).
Communication occurs by using key words. Your mobile phone can receive information about the controller’s measurements, active alarms,
supply water or room temperature. You can also read and change the
controller’s settings or control mode or switch the controller to a temperature drop or nominal temperature.

Control of a second heating circuit
An EXU-800 external unit can be
connected to the controller making
it possible to control a second heating circuit. As a result, e.g., heating
of damp rooms can be controlled
separately. For this to be possible,
the facility’s heating system must
be divided into two circuits.
With the help of the EXU-800 external unit, the controller can expand
to control two heating sources simultaneously. An older heating
source and a newer, more environment-friendly heating source can
be smartly controlled so that you
always have enough heat.
In addition, you can, e.g., use a
thermostat controlled relay to control the pump that charges the solar collectors’ accumulator. This
means that the controller always
starts the pump when solar heat
is available.

Intelligent heating controller for your home
EH-800 is a heating controller for private homes and business facilities having heating systems with circulating water. An external unit can be obtained as optional equipment making it possible to take a second control
circuit into use. If a second control circuit has been taken into use, numbers 1 or 2 will appear on the main
display indicating which control circuit is in use.
The EH-800 model has an intra/ internet connection (the EH-800 B model does not have it).
