2 UNIT DESCRIPTION

2.1 General

The Daikin EHOB*A*V1H wall-mounted gas boiler is a closed unit. The unit is intended to provide heat to the water of a CH-installation and the domestic hot water installation.

The air supply and combustible gas outlet can be connected to the unit by means of two separate pipes. A concentric connection can be supplied upon demand. The unit was tested in combination with the combi feedthrough, but the unit may also be connected to combi feedthroughs which meet the universal test standards for combi feedthroughs.

The unit can be connected to an assembly bracket if required, a frame with top connection, and various installation sets. These are provided separately.

The Daikin EHOB*A*V1H wall-mounted gas boilers have the CE marking, electrical protection class IPX4D

The unit is delivered for natural gas (G20) as a standard. On request, the unit can also be provided for propane (G31).

2.2 Functioning

The Daikin EHOB*A*V1H wall-mounted gas boiler is a modulating high-efficiency boiler. This means that the power is modulated to suit the required heat demand.

A copper CH circuit is integrated in the aluminum heat exchanger. The water of the DHW installation can be heated by connecting the unit to an indirectly

heated tank using a three-way valve and tank sensor (see par.5.1 and 5.2). The built in tank regulation of the unit ensures the domestic hot water provision takes precedence over the heating. Both cannot work at the same time.

The unit is fitted with an electronic boiler controller, which operates the fan at every heat requirement of the heating or the warm water supply, opens the gas valve, ignites the boiler controller, and continuously monitors and regulates the flame, depending on the requested power.

2.3 Operating modes

The operating mode of the unit is indicated by means of a code on the service display of the operating panel.

Off

The unit is not in operation, but is connected to the electricity supply. No response is given to requests for domestic hot water or CH water. The unit frost protection is active. This means that the pump will start running and the exchanger will be heated up if the temperature of the water in the system drops too far.

If the frost protection intervenes, the code The pressure in the CH installation can also be read from the temperature display in

this operating mode (in bar).

Standby

The LED at the key is lit and possibly one of the LEDs of the tap comfort function. The unit is ready to respond to a request for CH or tap water.

Post-running CH

After the end of the CH-operation, the pump will run for a specified time. The postpumping time is set to the value in par. 7.2 in its factory settings. This setting can be changed. In addition to this, the pump will run automatically 1 time per 24 hours, for 10 seconds, in order to prevent it from getting stuck. This automatic switching on of the pump takes place at the time of the last heating request. In order to change this, the room thermostat needs to be set higher for a moment, at the required time of day.

will be displayed (heating up exchanger).

Requested temperature reached

The boiler controller may temporarily block the heat request. The boiler controller will then be stopped. The block occurs because the required temperature has been reached. When the temperature has sufficiently decreased, the block will be lifted.

Selftest

Once every 24 hours, the boiler controller tests the connected sensors. During the test, the relay will not carry out any other tasks.

Daikin Europe NV

Ventilating

When the unit is started, the fan is first brought up to its correct start rpm. When the start rpm is reached, the boiler controller will be ignited. Code 3 is also visible when

there is post-fanning after the boiler controller is stopped.

Igniting

When the fan has reached the start rpm, the burner relay will be ignited by means of electrical sparks. During the ignition, code

not ignite, a new attempt will be made after approximately 15 seconds. If after 4 ignition attempts, the boiler controller has still not been ignited, the controller will go into downtime.

CH operation

An on/off thermostat, an OpenTherm thermostat, an outdoor sensor or a combination thereof can be connected to the controller (see par. 5.3 )

When there is a heat request from a thermostat, after the fan has started running (code

), the ignition will take place (code

During CH operation, the rpm of the fan and therefore the power of the unit can be adjusted so the temperature of the CH water to the required CH supply temperature can be controlled. If an on/off thermostat has been connected, this will be the CH supply temperature set on the display. In case of an OpenTherm thermostat, the required CH supply temperature is determined by the thermostat. In case of an outdoor sensor, the required CH supply temperature is determined by the fuel line programmed in the boiler controller. For the last two situations, the temperature set on the display is the maximum.

During CH operation, the requested CH supply temperature will be displayed on the operating panel.

The CH supply temperature can be set between 30 and 90°C (see par. 7.1). Caution: for a low temperature system, a lower maximum setting may be required than the standard setting of 80°C.

You can press the service button during CH operation to read the actual CH supply temperature.

4.2 Installation space

The unit must be installed against a wall with sufficient load bearing capacity. In case of light wall constructions, there is a risk of resonance noises. Within 1 meter of the unit, there must be an earthed wall plug. In order to prevent the condense outlet from freezing, the unit must be installed in a

frost-free room. Preferably ensure there is a space of at least 2 cm next to the boiler. No free space is required due to danger of singeing.

4.2.1 Installing in kitchen cabinet

The unit can be placed between two kitchen cabinets, or inside a kitchen cabinet. Make sure there is sufficient ventilation at the bottom and the top. If the unit is installed inside a cabinet, ventilation openings of at least 50 cm2 are

required.

4.2.2 Removing cover plate and front panel

For various activities on the unit, the cover plate and front panel have to be removed from the unit, if they were installed. Do this as follows:

• If you are using the cover plate (A), remove it to the front.

• Unscrew both screws (1) behind the display window.

• Pull the bottom of the front panel (2) forwards.

Danger: risk of burning

In case of high leaving water set ponts for space heating (eighter a high fixed set point or a high weather-dependent set point at low ambient temperatures), the heat exchanger of the boiler can be very hot, for example 70°C.

Beware that in case of a tapping demand, the water can initially have a higher water temperature than requested.

In this case, it is recommended to install a thermostatic valve to prevent scalding. This can be done according to the schematics below.

020601010

5.1 Connecting CH installation

1. Rinse the CH installation carefully.

2. Fit the supply pipe (A) and return pipe (B) to the connection set.

3. All pipes must be assembled with no electrical current, in order to prevent shocks from the pipes.

4. Existing connections may not be rotated, in order to prevent leakages.

The CH installation must be fitted with:

• A filling/draining tap (A) in the return pipe, immediately underneath the unit.

• A draining tap at the lowest point of the installation.

• An overflow valve (B) of 3 bar in the input pipe at a distance of no more than 500 mm

from the unit. Between the unit and the overflow valve there may be no valve or constriction.

• An expansion vessel in the return pipe (in the B-pack or in the installation).

• A check valve, if there are pipes running up, within close distance of the unit. This

prevents a thermosiphon effect from occurring during tap water operation (a non spring-operated return valve, must be assembled vertically).

5.1.1 Thermostatic radiator taps

If all radiators are fitted with thermostatic or cable radiator taps, a minimum water circulation must be safeguarded. See par. 7.5.

Daikin Europe NV

5.1.2 Dividing CH installation in groups in case of additional heat sources

Operating principle

If the room thermostat switches off the boiler because another heat source (wood heater, open fire etc.) heats the room, the other rooms may cool down. This can be resolved by splitting the CH installation into two zones. The zone with the external heat source (Z2) can be shut off from the main circuit by means of an electrical shut-off valve. Both zones are fitted with their own room thermostat.

Please note: This “external heat source” regulation may only be applied if no extra external tank has to be heated up (installation type 1).

Installation instructions

1. Install the valve in accordance with the connection diagram.

2. Connect the room thermostat of zone 1 to X4 – 6/7.

3. Connect the room thermostat of zone 2 to X4 – 11/12.

In principle, any on/off room thermostat can be combined with an outdoor sensor. Upon request of the room thermostat, the boiler will provide heat until the maximum set temperature in the boiler has been reached. This maximum set temperature is automatically regulated via the outdoor sensor, in accordance with the set fuel line in the boiler.

Connect the room outdoor sensor (see par. 10.2). For the fuel line setting, see the weather dependent regulation (see par. 0).

5.4 Connecting gas

1. Fit the gas valve directly on the 1/2" gas connection of the connection set using appropriate seal.

2. Place a gas sieve in the connection for the unit if the gas may be contaminated.

3. Connect the gas pipe in the gas valve using appropriate seal.

4. Check the gas carrying parts for leakages at a pressure of up to 50 mbar.

5. The gas pipe should be fitted pressure free.
