The product has two operating levels:

– The operator level shows the most im-portant information and offers set-upoptions which do not require any specialprior knowledge.

– Specialised knowledge is required in or-der to use the installer level (access forcompetent persons). This is thereforeprotected by an access code.

Operator level – overview (→ Page 15)

4 Operation

4.1 Starting up the product

4.1.1 Opening the isolator devices

Conditions: The competent person who installedthe unit will explain where the isolator devices areand how to handle them.

▶ Ensure that the gas isolator cock is fullyopen.

▶ Ensure that the stop cocks in the heat-ing installation's flow and return areopen.

▶ Ensure that the cold water stop cock isopen.

4.1.2 Starting up the product

12

▶ Press the (2) button.◁ When the unit is switched on, the

"Basic display" is shown in thedisplay (1).

4.2 Basic display

The filling pressure in the heating installa-tion and the operating mode are shown inthe display's basic display.To return to the basic display:– Wait more than five seconds without

pressing any buttons.If a fault message is present, the basicdisplay switches to the fault code.

4.3 Checking the heating systempressure

1. Once a month, check that the pressurein the central heating system, whichis displayed on the user interface,is between 0.1 MPa and 0.15 MPa(1.0 bar and 1.5 bar).◁ If the filling pressure is correct, no

action needs to be taken.▽ If the filling pressure is too low, add

more water to the heating installa-tion.

Operation 4

0020238423_02 Betacom 4 Operating instructions 11

NoteIf the heating flow temperatureis shown in the display, pressand hold the and buttonsat the same time for longer thanfive seconds, or temporarilydeactivate heating mode inorder to display the pressure.

2. Fill the heating installation. (→ Page 11)

4.4 Filling the heating installation

Caution.Risk of material damage dueto heating water that is ex-tremely calciferous or corros-ive or contaminated by chem-icals.

Unsuitable tap water damagesthe seals and diaphragms,blocks components in theproduct and heating installationthrough which the water flowsand causes noise.▶ Only fill the heating install-

ation with suitable heatingwater.

▶ In case of doubt, ask a com-petent person for details.

NoteThe competent person is respons-ible for filling the heating installa-tion the first time, any subsequenttop-ups and the water quality.The operator alone is respons-ible for topping up the water in theheating installation.

1. Open all radiator valves (thermostaticradiator valves) of the heating installa-tion.

2. Slowly open the filling cock, as shownto you by the competent person.

3. Fill with water until the required fillingpressure is reached.

4. Check the filling pressure in thedisplay.

5. Close the filling cock after filling.

4.11 Frost protection

4.11.1 The product's frostprotection function

The frost protection function switches onthe boiler and the pump as soon as theprotection temperature in the heating cir-cuit is reached.– Protection temperature: 12 ℃

The pump stops once the minimum wa-ter temperature in the heating circuit isreached.– Minimum water temperature: 15 ℃

If the burner ignition temperature in theheating circuit is reached, the burnerswitch is switched on and continuesto operate until the burner anti-cyclingtemperature is reached.– Burner ignition temperature: 7 ℃– Burner anti-cycling temperature: 35 ℃

The hot water circuit (cold and hot water)is not protected by the boiler.Frost protection for the system can only beguaranteed by the boiler.A controller is required to control the tem-perature of the system.

4.11.2 Frost protection for thesystem

NoteEnsure that the product's powerand gas supply are working cor-rectly.

Conditions: If you are away from home for severaldays, Without controller

▶ Switch the product to standby mode.(→ Page 12)

Conditions: If you are away from home for severaldays, With controller

▶ Program the number of days you willbe away in the controller to activate thefrost protection devices.

Conditions: If you are away from home for a pro-longed period

▶ Contact a qualified competent person,who can completely drain the system orprotect the heating circuit by adding aspecial frost protection agent for heatinginstallations.

5 Troubleshooting

5.1 Detecting and rectifying faults

▶ If problems occur whilst operating theproduct, you can carry out certain self-checks with the aid of the table in theappendix.Troubleshooting (→ Page 15)

▶ If the product still does not functionwithout problems after the checks havebeen carried out using the table, con-tact your competent person to rectifythe problem.

5.2 Fault codes in the display

Fault codes have priority over all other dis-plays. If several faults occur at the sametime, the corresponding codes are dis-played alternately for two seconds each.▶ If your product displays a fault code

(F.xx), contact a competent person.
