Function
Output for the activation of the
2-way directional valves (e.g. for
underfloor heating system, cooling)
Output for the activation of the
3-way directional valves (e.g. for
heating, hot water tank)
Output for switching on / off the
electric immersion heater
Input for room thermostat signals
Input for overload protection
of the hot water tank
volt free
Input for temperature sensor
of the hot water tank
Input for external control signal

For easy connection of a hot water tank provided by the customer,
Panasonic offers a temperature sensor installation kit for a foreign tank.
This article bears the designation CZ-TK1.
The outside temperature sensor is located in the outdoor or monobloc
unit and must not be installed or connected because the measured
values are transmitted via an internal BUS line.

5: Tank, 4: Heat
The maximum power of the hot water
electric immersion heater should be
maximum 3 kW
Terminals 13 / 14 must be bridged when
no overload protection is used for the hot
water storage
2 Kohlms @ 25 °C NTC
These two terminals are bridged during
delivery. Connection: 1-pole (min. 3 mm
contact gap)
Additional solar PCB required
Use additional circuit board CZ-NS1P,
CZ-NS2P or CZ-NS3P
