2.1 Mounting
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
Note:
Strong electromagnetic elds can impair the function of the controller.
ÎMake sure the controller as well as the system are not exposed to
strong electromagnetic elds.
The unit must only be located in dry interior rooms.
The controller must additionally be supplied from a double pole switch with contact
gap of at least 3 mm.
Please pay attention to separate routing of sensor cables and mains cables.
In order to mount the device to the wall, carry out the following steps:
ÎUnscrew the crosshead screw from the cover and remove it along with the
cover from the housing.
ÎMark the upper fastening point on the wall. Drill and fasten the enclosed wall
plug and screw leaving the head protruding.
ÎHang the housing from the upper fastening point and mark the lower fastening
point (centres 130 mm).
ÎInsert lower wall plug.
ÎFasten the housing to the wall with the lower fastening screw and tighten.
ÎCarry out the electrical wiring in accordance with the terminal allocation (see
chapter 2.2).
ÎPut the cover on the housing.
ÎAttach with the fastening screw.
2.2 Electrical connection
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
ATTENTION! ESD damage!
Electrostatic discharge can lead to damage to electronic com-
ponents!
ÎTake care to discharge properly before touching the
inside of the device! To do so, touch a grounded sur-
face such as a radiator or tap!
Note:
Connecting the device to the power supply must always be the last step
of the installation!
The controller is supplied with power via a mains cable. The power supply of the
device must be 100 … 240 V~ (50 … 60 Hz).
The controller is equipped with 4 relays in total, to which loads such as pumps,
valves, etc. can be connected:
• Relays 1 … 3 are semiconductor relays:
Conductor R1 … R3
Neutral conductor N
Protective conductor ⏚
• Relay 4 is a potential-free extra-low voltage relay
Depending on the product version, mains cables and sensor cables are already con-
nected to the device. If that is not the case, please proceed as follows:
Connect the temperature sensors (S1 to S3) to the following terminals with
either polarity:
S1 = Sensor 1 (outdoor temperature sensor)
S2 = Sensor 2 (heating circuit ow)
S3 = Sensor 3 (e. g. return sensor)
Connect the remote control (if used in the system selected) to the S3 / RTA12
input with either polarity.
Connect the room thermostat to the TA input with either polarity.
Connect the dew point switch (if used in the system selected) to the S5/ TS10
input with either polarity.

Installation Indications, functions and optionsOperation and function
en
Connect the RPS Grundfos Direct Sensor™ (pressure sensor) to the input S6.
S7 can be used as an input for a potential-free switch for the cooling mode.
Pins 2 and 3 come with a pluggable cable link already connected. If the contact is
closed (cable link connected), the heating mode will be active when demanded. If
the contact is open (cable link not connected) and the cooling option is activated,
the cooling mode will be active when demanded.
In order to connect a switch, cut the cable link and connect the switch to both
wires.
The terminal marked PWM A is the control output for a high-ef ciency pump.
If the Central Outdoor Sensor is to be used, connect it to the terminals marked
VBus with either polarity.

ÎUse a cable with a cross section of at least 0.75 mm² of the H05VV-F type for
connecting the device to the mains.
Note:
The connection depends on the system layout selected (see page 7).
The auxiliary terminals can be used instead of R4 as the mixer switch for the heat
generator, if a voltage higher than 30 V is applied.
Antifreeze: Standard function – if the temperature at S2 falls below 7 °C , the con-
troller activates the pump for 30 min, in order to reach 20 °C.
Outdoor sensor: If the outdoor temperature sensor is defective, 0 °C is used as
the reference value.

System 1 (fl ow temperature controlled heating with optional effi ciency
control of the heat exchange – fl ow controlled cooling)
Flow
Return
R2 = open
R3 = closed R1 S3 (optional)
S2
The controller monitors the room thermostat (TA).
If the room thermostat demands heat, the pump (R1) starts and R4 is energised for
the heating demand.The temperature at S2 is monitored.The mixer is controlled so
that the adjusted temperature Tset is reached and maintained at S2.
If the TFcalculated option (return temperature monitoring S3, factory setting =
active) is activated, the controller runs a heat demand-based calculation of the set
 ow temperature needed for keeping the system at the optimum temperature. For
this purpose, the return temperature (S3) is monitored. The calculated set  ow
temperature is displayed as TFset..
The controller is equipped with a non-adjustable safety shutdown function. If the
temperature at S2 reaches or exceeds 90 °C, the mixer closes. The warning symbol
⚠appears on the screen and the Lightwheel®  ashes yellow. If the temperature
at S2 reaches or exceeds 95 °C,R1 and R4 switch off. The Lightwheel®  ashes red.
If the TMax option is activated, the value for the safety shutown function can be
reduced. If the temperature at S2 exceeds TMax by less than 5 K, the warning sym-
bol ⚠appears on the screen and the Lightwheel®  ashes yellow. If the temperature
at S2 exceeds TMax by more than 5 K, R1 and R4 switch off. The Lightwheel®
 ashes red.
If the Cooling option is activated, the mixer is controlled so that the adjusted
cooling temperature TCool is reached and maintained at S2.The S7 contact can be
used for connecting a switch for remotely controlling the heating / cooling mode.
Contact open = cooling mode
Contact closed = heating mode
If the Condensation option is activated, the controller monitors a dew point
switch. If the dew point switch triggers an alarm, cooling stops and the warning
symbol is indicated. If the humidity falls again below the adjusted value, the cooling
mode continues.
