of accidents 

■ Legal instructions regarding environmental 

protection 

■ The Code of Practice of relevant trade 

associations 

■ All current safety regulations as 

defined by DIN, EN, DVGW, VDE and 

all locally applicable standards 

a ÖNORM, EN and ÖVE 

c SEV, SUVA, SVTI and SWKI 

Working on the system 

■ Isolate the system from the power supply 

and check that it is no longer 'live', 

e.g. by removing the separate fuse or 

by means of a main isolator 

Note 

In addition to the control circuit, there 

may be several power circuits. 

Danger 

Contact with 'live' components 

can lead to severe injuries.

Installing the external unit 

Please note 

! Avoid damaging the appliance 

during transportation. 

Never put weight on top of the 

appliance. 

Please note 

! If the compressor in the external 

unit is steeply angled, lubricant 

will enter the refrigerant circuit 

and damage the appliance. 

Compliance is required with the 

max. tilt angle according to the 

following table. 

Installation site requirements 

Installation location 

■ Select a location with good air circulation, 

so that the cooled air can dissipate 

and be replenished by warm air. 

■ Avoid direct insolation. 

Type 

Max. tilt angle 

AWB/AWB-AC 

201.B04 45° 

201.B07 45° 

201.B10 30° 

201.B13 30° 

■ When installing the unit where it is 

exposed to wind, ensure that the wind 

cannot influence the fan area. This 

might result in an "air short circuit" 

between the expelled and the inrushing 

air. Strong wind can have a negative 

influence on the evaporator ventilation. 

Please note 

! An "air short circuit" during 

heating operation will result in 

the cooled expelled air reentering 

the unit. This can lead 

to defrosting problems. 

Avoid "air short circuits". 

Installation 

5604 692 GB 

! 

Please note 

An "air short circuit" during 

cooling operation will result in 

the heated expelled air reentering 

the unit. This can lead 

to high pressure faults. 

Avoid "air short circuits". 

27


Installing the external unit (cont.) 

■ Take the lengths of the refrigerant 

lines into account (see "Connecting 

refrigerant lines"). 

■ Select the installation site so that the 

evaporator cannot be blocked by 

leaves, snow etc. 

■ Select the installation site with due 

consideration of the statutory regulations 

on sound dissipation and reflections. 

Technical guide "Heat pump 

principles" 

■ Never site in the corners of rooms, 

recesses or between walls. 

■ Never install next to or below bedroom 

windows. 

■ Never install closer than 3 m from 

pathways, downpipes or sealed surfaces. 

The cooled air in the discharge 

area creates a risk of ice forming when 

outside temperatures are below 

10 °C. 

■ The installation site should be easily 

accessible, for example for maintenance 

work (see "Minimum clearances"). 

Installation information 

■ Floor mounting: 

Use supports (accessories) for floor 

mounting. 

Where such supports cannot be used, 

install the external unit freestanding on 

a solid base of at least 100 mm height. 

In difficult climatic circumstances 

(temperatures below zero, snow, 

humidity) install the appliance on a 

plinth of approx. 300 mm height. 

Take account of the weight of the 

external unit (see following table). 

■ Wall mounting: 

Use the wall mounting bracket set 

(accessory). 

■ Never install with the discharge side 

facing the main wind direction. 

■ Observe the wind loads when installing 

the unit on sites exposed to the 

wind. 

■ When mounting the unit on a wall, the 

wall must offer sufficient load-bearing 

capacity. 

■ Design wall outlets and protective 

pipes for the refrigerant lines and electrical 

cables without moulded parts 

and changes of direction. 

■ Incorporate the external unit into the 

lightning protection system. 

■ Consider the heat emitted by the unit 

when planning your weatherproofing 

measures or an enclosure. 

■ Ensure the condensate can drain 

freely, and create a permanent gravel 

bed below the external unit as a soakaway. 

5604 692 GB 

28



■ In regions with prolonged cold seasons 

(e.g. in Germany), provide an 

electric supplementary heating facility 

(accessory) for the condensate pan. 

■ For insulation of structure-borne noise 

and vibrations between the building 

and the external unit, consider the following 

measures: 

– Fit pipe bends to provide vibration 

compensation in refrigerant lines. 

– Route electrical cables/leads 

between the internal and external 

units free of stress. 

– Installation only on walls with high 

weight per area (> 250 kg/m 2 ), in 

other words not on lightweight walls, 

roof structure etc. 

– When mounting the unit on the floor, 

use only the rubber buffers supplied; 

for wall mounting use the anti-vibration 

mount supplied with the wall 

mounting bracket set; never use 

additional anti-vibration mounts, 

springs, rubber buffers etc.

and a pipe vent to the public sewer. 

Note 

■ In underfloor heating circuits, install a 

temperature limiter to limit the maximum 

temperature for underfloor heating 

systems (see page 8) 

■ Safeguard minimum flow rate, e.g. 

with overflow valve (see Specification 

on page 125) 

Connecting a cooling circuit if required 

For area cooling systems (e.g. underfloor 

heating circuit, chilled ceiling), a 

contact humidistat (accessory) is 

required. 

Requirements for the contact humidistat: 

■ Electrical connection: 230 V~, 0.5 A 

■ Installation inside the room to be 

cooled at the cooling water flow 

(remove thermal insulation if required) 

■ If several rooms with different relative 

humidity are part of the cooling circuit, 

fit and connect several contact humidistats 

in series: 

Switching contacts as N/C contacts 

Electrical connections 

Routing electrical cables to the wiring chamber of the internal 

unit 

Danger 

Damaged cable insulation can 

cause injury and damage to the 

appliance. 

Route cables so that they cannot 

touch very hot, vibrating or sharpedged 

components. 

Danger 

Incorrectly routed wiring can lead 

to serious injury from electrical 

current and result in equipment 

damage. 

5604 692 GB 

42


Electrical connections (cont.) 

■ Route LV leads < 42 V and 

cables > 42 V/230 V~/400 V~ 

separately. 

■ Strip the insulation from the 

cables as close to the terminals 

as possible, and bundle tightly 

to the corresponding terminals. 

■ Secure cables with cable ties. 

This ensures that, should there 

be an error, for example when 

detaching a wire, the wires cannot 

drift into the adjacent voltage 

area. 

! 

Please note 

From a safety viewpoint, the BUS 

cable for the internal/external unit 

(12 V or 43 V) does not count as 

an LV lead. 

The BUS cable must be routed 

together with the 230 V cables. 

Note 

To ensure that the control panel can be 

placed in the service position (see 

page 90), all connections on the control 

panel (see page 45) must be made 

with flexible cables.

■ Route 230 V~ cables and LV cables 

separately and bundle them tightly 

together at the terminals. This ensures 

that, in case of failure, for example 

when detaching a wire, the wires cannot 

drift into the adjacent voltage area. 

■ Strip the insulation as close to the terminals 

as possible. 

■ If two components are connected to 

the same terminal, press both wires 

together into a single wire ferrule.

Information regarding the connection 

values 

■ The output given is the recommended 

connected load. 

■ The total output of all components connected 

directly to the heat pump control 

unit must not exceed 1000 W (e.g. 

pumps, valves, message facilities, 

contactors). 

If the total output < 1000 W, the individual 

rating of a component (e.g. 

pump, valve, message facility, contactor) 

can be greater than specified. 

However, never exceed the breaking 

capacity of the corresponding relay. 

■ The stated current indicates the max. 

switching current of the switching contact 

(observe the total current of 5 A). 

■ Safety LV is unsuitable for controlling 

external heat sources.

Power supply 

Isolators for non-earthed conductors 

■ The mains isolator (if installed) must 

simultaneously isolate all non-earthed 

conductors from the power supply with 

a minimum contact separation of 3 mm 

■ We additionally recommend installing 

an AC/DC-sensitive RCD (RCD class 

B ) for DC (fault) currents that 

can occur with energy efficient equipment 

■ If no mains isolator is installed, all nonearthed 

conductors must be isolated 

from the power supply by the upstream 

circuit breakers with at least 3 mm contact 

separation 

Danger 

Incorrectly executed electrical 

installations can lead to injury 

from electrical current and result 

in equipment damage. 

Make the power supply connection 

and implement all protective 

measures (e.g. RCD circuit) in 

accordance with the following 

regulations: 

■ IEC 60364-4-41 

■ VDE regulations 

■ Technical connection requirements 

specified by your local 

power supply utility 

■ Protect the power supply to the 

heat pump control unit with 

max. 16 A 

Danger 

An absence of component earthing 

in the system can lead to serious 

injury from electrical current 

if an electrical fault occurs. 

Connect the appliance and pipework 

to the equipotential bonding 

of the house in question. 

Danger 

Incorrect core allocation can 

cause severe injury and damage 

the appliance. 

Never interchange cores "L" and 

"N". 

■ In negotiations with your power supply 

utility, different supply tariffs for the 

main power circuits may be offered. 

Observe the technical connection 

requirements of the power supply utility 

■ If the compressor and/or instantaneous 

heating water heater are operated 

at an economy tariff (power-OFF), 

either provide an additional cable (e.g. 

3 x 1.5 mm 2 ) for the power-OFF signal 

from the distribution board (meter box) 

to the heat pump control unit 

or 

Combine the cable for the power-OFF 

signal and for the heat pump control 

unit power supply (3 x 1.5 mm 2 ) in a 5- 

core cable 

■ The allocation of the power-OFF (for 

compressor and/or instantaneous 

heating water heater) is made via the 

type of connection and by setting 

parameters in the heat pump control 

unit. 

In Germany, the power supply can be 

cut off for up to 3 x 2 hours per day 

(24 h) 

5604 692 GB

Power supply (cont.) 

■ The heat pump control unit/PCB 

must be supplied without power-OFF; 

tariffs that are subject to possible shutdown 

must not be used here 

■ Protect the power supply to the heat 

pump control unit with max. 16 A 

■ For accessories and external components 

that are not to be connected to 

the heat pump control unit, connect the 

power supply with the same phase as 

the heat pump control unit; we recommend 

using the same fuse/MCB. 

Connection to the same fuse/MCB 

provides additional safety when the 

power is switched off. Observe the 

power consumption of the connected 

consumers

the refrigerant lines in the internal and 

external units. 

Note 

Work on the refrigerant circuit may only 

by carried out by certified personnel 

(according to EC Directives 842/2006 

and 303/2008). 

Filling and venting on the secondary side 

Unsuitable fill and top-up water increases 

the level of deposits and corrosion 

and may lead to system damage. 

Regarding the quality and amount of 

heating water, incl. fill and top-up water, 

observe the VDI 2035 [or local regulations]. 

■ Thoroughly flush the entire heating 

system prior to filling it with water. 

■ Only use fill water of potable quality. 

■ Soften fill water with a hardness above 

16.8 °dH (3.0 mol/m 3 ), e.g. with the 

small softening system for heating 

water (see the Viessmann Vitoset 

pricelist).

■ Max. power loss ≤ 2.5 W 

Fuse F101: 

■ T 1.0AL 

■ Max. power loss ≤ 2.5 W 

Danger 

Touching 'live' components can 

result in severe injury due to electric 

shock. 

Before working on the appliance, 

always ensure that the main 

power circuit is also isolated. 

Removing this fuse does not 

isolate the main power circuit.
