THE ROOM THERMOSTAT FOR THE COOLING FUNCTION
The room thermostat is used to switch the cooling func-
tion on and off:
I Cooling function on
Cooling function off
UTILIZATION OF THE COOLING FUNCTION
The heating and heat pump regulation program activates
the cooling function only if the following conditions are
fulfilled:
t
Heat pump model must have integrated cooling
function.
t
Room thermostat for the cooling function must
be switched on.
t
Temperature of the heat source must be ≥ +5 °C.
t
Heat pump must not currently be occupied with
“heating” or “water heating”.
If the heat pump regulation program sends the
command “water heating” to the heat pump, the
cooling function of the heat pump automatically
stops as long as the water is heating.
t
The “Automatic” setting must be selected on the
control element under “Operating mode: cool-
ing”.
t
The outdoor temperature release set on the con-
trol element must be exceeded.

regulator.
The cooling function can be used in two variants:
Variant 1:
Manual switching from heating to cooling opera-
tion (and vice versa). This variant operates at a
pre-set forward flow temperature.
Operating manual of the heating and heat pump
regulator.
Variant 2:
Automatic switching from heating to cooling op-
eration (and vice versa). This variant can operate
using a cooling curve.
NOTICE.
Variant 2 is possible only if a Comfort
board (available at extra charge) is built
into the heating and heat pump regulator.

Care of the unit
The outer surfaces of the unit can be cleaned with a
damp cloth and household cleaning products.
Do not use cleaning or care products that contain abra-
sives, acids and/or chlorine. Such products would de-
stroy the surfaces and could also damage the technical
components of the unit.
Maintenance of the unit
The cooling circuit of the heat pump requires no regu-
lar maintenance.
According to EU regulation (EC) 842/2006 of May 17,
2006, leak inspections and maintenance of a log book
are required by law for certain heat pumps!
The criteria for conducting leak inspections and
maintaining a log book are based on the hermetic
impermeability of the cooling circuit and the refrigerant
capacity of the heat pump! No log book is required for
heat pumps with a refrigerant capacity of < 3kg. With all
other heat pumps, the log book is included with all other
delivered materials.
Log book for heat pumps, Section “Information
on use of the log book”.
The components of the heating circuit and the heat
source (valves, expansion vessels, circulating pumps,
filters, dirt traps) should be inspected as well as cleaned
as needed - at the very least annually - by a qualified
heating or cooling system technician.
