The domestic hot water sensor is an optional accessory and only
functionally-relevant for a separate domestic hot water tank. You
may only use domestic hot water sensors which have been ap-
proved by the manufacturer of the heat pump.
ATTENTION
The domestic hot water tank must be lled before con-
necting the domestic hot water sensor to the heating and
heat pump regulator.
If not already prepared at the factory, mount the domestic hot
water sensor (Ø = 6 mm) on the halfway level of the domestic hot
water tank – and always above the internal heat exchanger of the
domestic hot water tank.
1 Domestic hot water connection
2 Cold water connection
3 Heat exchanger
4 Domestic hot water sensor (Ø = 6 mm)
5 Hot-water tank
External return ow sensor
The return ow sensor (optional accessory) is functionally-rele-
vant for hydraulic integration of an isolating tank (multifunction
tank .). This has to be installed as follows:
ZUP TRLext HUP
1 Separation or multi-functional storage tank
2 Circulation pump in the separation storage
tank (heat pump circuit)
3 Circulation pump from the separation storage
tank (heating circuit)
4 External return sensor (Ø = 6 mm)
ZUP Charging loop, heat pump
HUP Discharging loop, heating circuit
Connect the return ow sensor coming from the isolating tank to
the circuit board of the heating and heat pump regulator.
ASSEMBLY AND INSTALLATION OF SENSORS
The external sensor is a function-critical accessory and included
in the scope of supply.
NOTE
If the external sensor is not installed or defective, the heat-
ing and heat pump regulator automatically sets the exter-
nal temperature to -5 °C. The status display of the operat-
ing element lights up red, the screen of the operating ele-
ment reports a fault.
ATTENTION
Mount the external sensor on the north or northeast side
of buildings. The sensor must not be exposed to direct
sunlight.
ATTENTION
Make sure that water cannot penetrate the housing of the ex-
ternal sensor at any time. If necessary (e.g. during the construc-
tion phase), seal the cable gland separately.
1. Open the housing of the external sensor and align ≥ 2 m
over the base of the fastening point. The cable gland must
point to the base.

“Valid updates” (“Gültiges Updates”) list on the screen.
Switching on for the rst time /
Commissioning
A self-test starts when the controller voltage is switched on or af-
ter a restart of the heating and heat pump controller (reset). This
self-test checks whether basic heat pump components are avail-
able.
The displayed components vary according to heat pump
type.
The self-test can take up to 5 minutes.
The language selection then appears for a heat pump that has
not yet been congured (switching on for the rst time).
Select the display language: part 1 of the controller manual,
section “Basis information on the operation“.
NOTE
The language must be conrmed in any case.
Then click on the navigation arrow in the language display. A se-
curity prompt will then appear.
The safety prompt always appears when the control-
ler voltage is switched on or after a restart of the heating
and heat pump controller (reset).
This screen is no longer displayed if the heat pump or
ZWE1 has more than 10 operating hours.
No ZWE (second heat generator) is released by the controller until
the display is conrmed with .
NOTE
No heat generator runs during a cold start of air/water heat
pumps.
ATTENTION
The unit can be damaged if the display is conrmed with
, although the system is not properly lled.

For brine/water heatpumps it is necessary to select which heat
source uid is to be used.
Brine
Must be selected if the heat pump is operated with a
brine-water mixture (= standard). Whether probes or
surface collectors are used is irrelevant.
If there is an intermediate heat exchanger on the heat source
side:
Water Brine
Must be selected if water is used as the heat source me-
dium on the primary side of the intermediate heat ex-
changer and a brine-water mixture is used on its second-
ary side.
Water Water
Must be selected if water is used as the heat source me-
dium on both the primary and secondary sides of the in-
termediate heat exchanger. For the water/water setting
the heat source inlet temperature must be at least 7°C or
higher.
The minimum temperature of the heat source (T-HS min) is set au-
tomatically depending on the medium selected.
page 41, “System setting during commissioning“, “T-HS
min”
NOTE
If no heat source is selected and the query is only answered
by controlling and selecting , “Brine” is automatically set
as the heat source.
A later change of the heat source medium as well as of “T-
HS min” is only possible with customer service access.
If this screen
is displayed, disconnect the heating and heat pump controller
from the mains supply, check the 3-pin cable for the BUS connec-
tion and rectify the fault if necessary.
Finally, the navigation screen appears.
NOTE
With some units, the compressor is rst heated up.
The heating phase until the compressor starts can take
several hours when starting up for the rst time.
With dual air/water heat pumps the ow is monitored
while the pump is running. If the ow is not ok, the heat
pump does not start up and no error is displayed. To this
end, check the ASD input, if it is not set to ON the ow is
too low.
page 14, “Query inputs“
As long as the heat pump has not yet been congured, the “GO”
symbol ashes at the top right of the navigation screen:
By selecting and clicking the symbol “GO”, the startup guide is
called up. The symbol “GO” will disappear as soon as initial com-
missioning is complete.
page 33, “Startup guide“ and page 33, “Startup parame-
ter back“
