The appliance is intended solely for installation and

operation in sealed unvented heating systems that

comply with EN 12828, with due attention paid to

CECS 215-2017 and the associated installation, serv-

ice and operating instructions. It is only designed for

heating up heating water that is of potable water qual-

ity.

Intended use presupposes that a fixed installation in

conjunction with permissible, system-specific compo-

nents has been carried out.

The appliance is intended exclusively for domestic or

semi-domestic use; even users who have not had any

instruction are able to operate the appliance safely.

Commercial or industrial usage for a purpose other

than heating the building or DHW shall be deemed

inappropriate.

Any usage beyond this must be approved by the man-

ufacturer in each individual case.

Incorrect usage or operation of the appliance (e.g. the

appliance being opened by the system user) is prohibi-

ted and will result in an exclusion of liability. Incorrect

usage also occurs if the components in the heating

system are modified from their intended use (e.g. if the

flue gas and ventilation air paths are sealed).

Product information

The control unit is a boiler and heating circuit control

unit for the following operating modes:

■Weather-compensated mode

■Continuous operation

■Room temperature-dependent mode

Your heating contractor will configure the operating

mode during commissioning in accordance with your

heating system. These instructions describe all 3 oper-

ating modes.

Weather-compensated mode

Fig. 1

In weather-compensated mode, the flow temperature

level is controlled according to the outside tempera-

ture. The lower the outside temperature, the higher the

flow temperature. This means that more heat is provi-

ded for central heating on cold days than on warmer

days.

In weather-compensated mode, 1 heating circuit with-

out mixer and up to 2 heating circuits with mixer can

be operated with the control unit.

Continuous operation

Fig. 2

In continuous operation, the heat generator provides

heating water with a constant flow temperature regard-

less of the outside temperature.

In continuous operation, 1 heating circuit without mixer

and up to 2 heating circuits with mixer can be operated

with the control unit.
