a Switch box
Contains the main electronic and electrical parts of the indoor unit.
b User interface (optional)
c Manometer
Allows readout of the water pressure in the water circuit.
d Air purge valve
Remaining air in the water circuit will be automatically removed via
the air purge valve.
e Expansion vessel (10l)
f Flow sensor
Gives feedback to the interface about the actual flow. Based on this
information (and other), the interface adjusts the pump speed.
g Heat exchanger
h Water pump
Circulates the water in the water circuit.
i Water filter
Removes dirt from the water to prevent damage to the pump or
blockage of the heat exchanger.
j Pressure relief valve
Prevents excessive water pressure in the water circuit by opening at
3bar.
k Refrigerant gas connection R410A
l Refrigerant liquid connection R410A
m Water inlet connection
n Drain and fill valves
o Shut-off valves (accessory)
Allows isolation of the indoor unit water circuit side from the
residential water circuit side.
p Water outlet connection
q Thermistors
Determines the water and refrigerant temperature at various points in
the circuit.
r Backup heater thermal fuse
The fuse is blown when the temperature becomes higher than the
backup heater thermal protector temperature.
s Backup heater thermal protector
The protector activates when the temperature of the backup heater
becomes too high.
t Backup heater
Provides additional heating in case of cold outdoor temperatures.
Also serves as backup in case of malfunctioning of the outdoor unit.
u Air valve
