Do not acknowledge fault mes-

sages several times in quick suc-

cession. Inform your heating con-

tractor so the cause can be ana-

lysed and the fault rectified.

If there is a fire

Danger

Fires create a risk of burns.

■

Switch the system off.

■

Use a tested fire extinguisher,

class ABC.

Conditions for siting

Danger

Easily flammable liquids and mate-

rials (e.g. naphtha/petrol, solvents,

cleaning agents, paints or paper)

can cause deflagration and fire.

Never store or use such materials

No liability is accepted for loss of profit, unattained

savings, or other direct or indirect consequential losses

resulting from the use of an internet or bus communi-

cation interface, or a remote maintenance service. No

liability is accepted for losses resulting from inappropri-

Liability is limited to typical damage arising if a funda-

mental contractual obligation is violated through slight

negligence, the fulfilment of which is essential for

proper execution of the contract.

The limitation of liability shall not apply if the damage

was caused deliberately or through gross negligence,

Terminology

To provide you with a better understanding of the func-

tions of your heat pump control unit, some terminology

is explained. This information can be found in chapter

"Terminology" in the Appendix.

Intended use

The appliance is intended solely for installation and

operation in sealed unvented heating systems that

comply with EN 12828, with due attention paid to the

associated installation, service and operating instruc-

tions.

Intended use presupposes that a fixed installation in

conjunction with permissible, system-specific compo-

nents has been carried out.

Commercial or industrial usage for a purpose other

than central heating/cooling or DHW heating shall be

deemed inappropriate.

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 function.

Introductory information

Symbols

5838122

Depending on the type of heat pump and accessories

installed, your heating system may be equipped as fol-

lows:

■

Heating:

Central heating and, if installed, heating of heating

water buffer cylinders

■

Cooling:

The "natural cooling" and "active cooling" functions

are supported if the required accessories are instal-

led.

■

DHW heating:

DHW heating using an external DHW cylinder, and

control of a DHW circulation pump are possible.

Commissioning

The commissioning and matching up of the heat pump

control unit to local conditions and to the structural

characteristics of the building, plus the instruction of

the user in operating the system, must be carried out

by your heating contractor.

Note

These operating instructions also describe functions

that are only available on some heat pump models or

only with accessories. These functions are not specifi-

cally identified.

For questions relating to the scope of functions and

accessories for your heat pump and your heating sys-

tem, check with your contractor.

The DHW cylinder can be heated at certain times with

4 "time switches" for "standard heating" and 2

"time switches" for "high heating".

Note

For the heat pump to heat the DHW cylinder, there

must be a demand from the DHW cylinder and at least

one of the time switches must be active.

"Standard heating":

The DHW cylinder is heated to the fixed set buffer tem-

perature (e.g. 50 °C). (Recommended for times when

a DHW demand is present, e.g. early in the morning

and evening)

"High heating":

The DHW cylinder is heated to a higher temperature

(e.g. 65 °C) to improve drinking water hygiene.
