Installation of the room
thermostat for the cooling
function
This chapter is relevant for you only if you are using a
heat pump with a
model designator K
.
CAUTION.
If floor heating systems are to be used for
cooling, the manufacturer must approve
the floor structure (especially the screed)
for use of the cooling function.
Use the room thermostat of the cooling function in a
reference room as a reference variable. If the tempera-
ture in the reference room falls below the set tempera-
ture, the cooling function of the heat pump will automat-
ically shut off.
Operating manual of the heat pump and heating
regulator, “Cooling” chapter.
NOTICE.
You must install the room thermostat in a
reference room in addition to single-room
regulators.
You must install single-room regulators for
switching from heating to cooling (and vice
versa).
NOTICE.
Always comply with the applicable stand-
ards and directives.
Hot-water tank
If the heat pump will be used for heating hot water, you
must integrate special hot-water tanks in the heat pump
system.
NOTICE.
The hot-water tank must be equipped with
a heat exchanger, which is adapted to the
heating capacity of the heat pump.
We offer a variety of hot-water tanks for you to choose
from. They are optimized for use with your heat pump.
NOTICE.
Integrate the hot-water tank in the heat
pump system corresponding to the hy-
draulic diagram for your system.
For heating hot water, you must install a 3-way switching
valve in the hot water outflow (forward flow).
The 3-way switching valve is an accessory and is not in-
cluded in the scope of delivery.
Commissioning
Proceed as follows:
Conduct a thorough installation inspection and go
through the items on the general checklist.
“General checklist”.
The installation inspection will prevent damage
to the heat pump system that could be caused by
incorrect installation work.
Make sure of the following…
t
Clockwise rotary field
of the load power supply
(compressor).
t
Installation and assembly
of the heat pump
according to the information in this operating
manual.
t
All electric installation work must be properly
completed.
t
A
3-pole automatic circuit-breaker
must
be installed for the compressor. It must have a
contact gap of at least 3 mm.
t
The heating circuit must be rinsed, filled and
thoroughly bled.
t
All valves and shut-off devices of the heating
circuit must be open.
t
All pipe systems and components of the system
must be sealed.
