Heating controller OUMAN EH-800B

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.

Heating controller OUMAN EH-800B 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

Heating controller EH-800B automatically controls the temperature

Heating controller EH-800B automatically controls the temperature of the water entering the heating network. The heating need changes according to the outdoor temperature.		As the outdoor temperature gets colder, the controller lets just enough heat into the network to keep the room temperature at an even level

Heating controller EH-800B is easily and quickly installed

Heating controller EH-800B is compatible with the most commonly used boiler and accumulator valves. Installation sets for Belimon district heat  valves and Esben VRG valves can be obtained as optional equipment. You can install it yourself without any special tools.

Detach the control knob from the valve and put the mounting kit into place. Press EH-800B into place, connect the sensors, plug it in and the unit is ready to use!

Easy to take into use

Heating controller EH-800B 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.

The heating controller EH-800B 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).

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.

Central water heating houses
Heating controller OUMAN EH-800B 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.

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 set ting changes taking into account the room sensor if it is connected.

Diverse time programs Use the controller’s week/24 hour clock to program energy conserving temperature drops coinciding with your own weekly rhythm. Use the exception calendar to program temperature drops ahead of time for holidays or other exceptional days.		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. The controller automatically corrects the curve if the user sets an unusual curve. It is also possible to select a 5 point curve that is freely adjustable.

The heating controller OUMAN EH-800B can not be used either with a home network or an internet web browser

The heating controller OUMAN EH-800 model has an intra/ internet connection.

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-800B 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.

Control of hybrid heating

With the help of the EXU-800B 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.

Heating controller OUMAN EH-800B 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.
