Planning
Key for the Hydraulic Part
E26 Main PCB: The maximum cable length for sensor inputs is 30 m.
The maximum cable length for other inputs and other outputs is
50 m.
E27 2-way valve: Opened in heating mode and closed in cooling
mode.
E28 3-way valve: Opened in drinking water preparation and closed in
heating or cooling mode.
E29 Optional Thermostat: Every heating circuit can be controlled by
means of an optional thermostat (E29 for one heating circuit,
E53 and E54 for two heating circuits), either in combination with
a room temperature sensor (E37 for one heating circuit, E40 and
E41 for two heating circuits) or by means of the operating unit
(E33, this can only be used for one heating circuit).
E30 Hot water tank E-heating element
E31 Control output for additional circulation pump
E32 On/off switch of the bivalent heat source (dry contact)
E33 Operating unit: The operating unit of the heat pumps of the
H Generation can be used for one heating circuit as a room
thermostat. The maximum cable length is 50 m.
E34 External on/off switch (dry contact)
E35 Temperature sensor for hot water tank
E36 Outdoor temperature sensor (optional)
E37 Room temperature sensor for heatC. 1 (see explanation for E29)
E38 Overload protection of the domestic hot water tank E-heating el-
ement: If an external hot water tank uses E-heating element and
is controlled by means of the Panasonic heat pump, a contact
bridge must be placed at this entrance.
E39 Optional additional PCB CZ-NS4P: The maximum cable length
for sensor inputs is 30 m. The maximum cable length for other
inputs and other outputs is 50 m. If the optional supplementary
PCB is installed, the connections for the external room thermo-
stats 1 and the room temperature sensor 1 are deactivated on
the main PCB.
