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-effi ciency pump.
If the Central Outdoor Sensor is to be used, connect it to the terminals marked
VBus with either polarity.

Use 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.
