

Air is the source of heat



Intended for attendance-free water heating up to

55°C.



Suitable for floor and radiator heating systems



Compressor cooling support



Hot water for space heating and service hot water

supply central control by means of supplied

regulation system



Choice from two regulators and an option for further

extension



Wired or wireless control



Stainless steel, unpainted finish



Wide range of accessories

electronics for affordable price.

Installation position

Intended for outdoor installation next to a building

structure or on its roof

Characteristics

Heat source: air

Noise suppression:



Use of scroll compressor design eliminates

traditional pistons and valves



Compressor and cooling circuit multiple spring

suspension



Solid and compact foundation slab



Multiple layer noise-proof insulation on covers



Low speed, 630mm large diameter serrated blades

fan



Control units:



AVS37 (standard) control panel in switchboard

without space temperature sensing (resolved with

the use of an external thermostat)



QAA78 wireless unit (optional) combined space and

service device



QAA78 advantages:



the heat pump and the hot water for space heating

and service hot water supply can be controlled from

anywhere in the house/building



space thermostat function, informs the regulator of

the local unit’s temperature status



Heating system connection support /

alternatives:



direct connection to the heating system without

using a storage reservoir



Two or four-point connection to the storage reservoir



Storage reservoir support by means of a floating

boiler



Storage reservoir (accumulation tank):



not required (subject to evaluation)



equithermal charging availability



availability of so-called forced charging, when the

required temperature is reached through charging.

The function’s initiation can be linked to time or

command controlled switching between electricity

tariffs. The advantage is the possibility of heat

“collection” during favourable weather conditions,

e.g. during higher air temperatures.



Bivalent source:



electrical cartridges support in the flow or in the

reservoir



External sources support (existing gas, electricity

and other energy driven boilers)



Three or single-stage bivalent controlز
