Safety instructions

Please follow these safety instructions closely to prevent accidents and

material losses.

Safety regulations

Installation, initial start-up, inspection,

maintenance and repairs must only

be carried out by a competent

person (heating engineer/installation

contractor).

Observe all current safety regulations

as defined by DIN, EN, DVGW and

VDE or locally applicable standards.

See also the safety instructions sheet

in the Vitotec technical documentation

folder.

efore working on the equipment/

heating system/solar heating system,

isolate its mains electrical supply

(e.g. by removing a separate mains

fuse or by means of a mains

electrical isolator) and safeguard

against unauthorised reconnection.

Earthing/lightning protection of the

solar heating system

Install an electrical conductor on the

pipework system of the solar circuit

in the lower part of the building in

accordance with VDE or local

regulations.

The connection of the collector

system to an existing or new

lightning conductor system or the

creation of local earth bonding must

only be carried out by authorised

trained personnel under observation

of local conditions.

Repair work

It is not permitted to carry out

repairs on parts that fulfil a safety

function.

Use only original Viessmann spare

parts, or equivalent parts that have

been approved by Viessmann.

Initial start up

The initial start-up must be carried

out by the system installer or a

designated commissioning engineer.

All actual values should be recorded

in a commissioning/service report.

Instructing the system user

The system installer must hand the

operating instructions to the system

user and instruct him/her in the

operation of the system.

System design

Dual mode DHW heating with VitocellĆBĂ100 or VitocellĆBĂ300

DHW heating without solar energy

The upper indirect coil of the DHW

cylinder is heated by a boiler. The

cylinder thermostat with cylinder

temperature sensorĂ6 of the boiler

control unit switches cylinder

loading pumpĂ7Ă.

DHW with solar energy

When a temperature difference

higher than the start-up temperature

differentialĂDO set in control unitĂ1

is measured between collector

temperature sensorĂ2 and cylinder

temperature sensorĂ3, solar circuit

pumpĂ4 is switched ON and the

DHW cylinder is heated up. The pump

will be switched OFF if the actual

temperature falls below shutdown

temperature differentialĂDF.

The temperature in the DHW cylinder

is limited by the electronic

temperature limiter (safety shutdown

at 90ĂºC) in control unitĂ1 or by high

limit safety cut-outĂ5 (if required).

When the preset temperature is

exceeded, these devices switch OFF

solar circuit pumpĂ4.

The pasteurisation requirements are

met by circulation pumpĂ8 and

sufficient heat input. Circulation

(relayering) starts if 60ĂºC is not

reached inside the DHW cylinder.

ĂSafety instructions

With temperatures higher than 60 ºC,

limit the HW temperature to 60 ºC

by installing a mixing device, e.g. a

thermostatic mixing valve ( HW

cylinder accessory). The mixing

equipment does not prevent the risk

of scalding at the tap. The

installation of a mixer tap at the

draw-off point is required.

Regulations

Carry out the mains connection and all earthing measures (e.g. fault current

circuit) in accordance with IECĂ364, the requirements of your local electricity

supplier, VDE regulations or all local and national regulations. The power

supply to the control unit should be protected by a fuse with a max. rating of

16ĂA.

Make the mains power supply connection (230ĂV~) via a mains isolator

(two-pole) to be provided on site.

Disconnect the system by means of a device which simultaneously separates

all non-earthed conductors with at least 3Ămm contact separation.
