Input terminals X4
X4-81 Offset roomstat / remote control
X4-82 External sensor
X4-83 Return / buffer or heat generators
For cascade systems, the sensor must be
positioned in the lower area of the buffer storage
tank.
X4-84 Hot water sensor (tank / boiler sensor)
Positioned in the top area of the Hygienik and
layer separate plate. With separate storage tanks
(separate buffer tank and Hygienik without layer
separate plate), this sensor must be positioned in
the lower area of the Hygienik.
X4-85 Heating circuit one flow sensor
X4-86 Variable input VA1
(Assignment may vary depending on setting)
X4-87 and 88 variable inputs, see X4-86
X4-89 Heating circuit two flow sensor
X4-90 Collector sensor
X4-91 Solar sensor (storage tank reference tempe-
rature) This sensor must be positioned at the
bottom in the buffer tank.
Grey
connections have already been conducted. All other
connections must be conducted as required.

X5-1 Air inlet sensor
X5-2 Defrost sensor
X5-3 Condensation sensor
X5-4 ND limiter
X5-5 HD limiter
X5-6 Starting current limiter
X5-7 Fan error message
X5-8 power supply company block
A break contact can be used by the control sys-
tem to detect a block from the local power supply
company. The heat pump is then blocked for this
period.
If no contact is available via a ripple control signal conver-
ter, a relay must be actuated via the primary power supply.
If the contact is not opened when the primary circuit is shut
down, the heat pump (fan) issues an error message which
needs to be reset manually.
