1 - INTRODUCTION
1.1 - General information
The hydronic module is the indoor unit of the 38AW heat
pump range.
It is used in combination with floor circuit, fan coil units,
radiators, domestic hot water tank (with or without solar
integration).
The hydronic module controls the CDU and the other
heat/cool sources, to achieve the desired temperature in the
heating/cooling zones and in the domestic hot water tank.

T1, T2, T3: Terminals
C1, C2, C3: Thermostats connected to terminals
C: User interface (additional or shifted from the unit) or
thermostat connected to the hydronic module
Terminals
Terminals can be of the following types:
• Floor circuit
• Fan coils
• Radiators
• Low temperature radiators.
Different terminals have different water temperature
requirements.
To ensure comfort, do NOT use terminals with different
water temperature requirements at the same time.
Example: It is possible to use floor circuit for heating, and
fan coil for cooling, but using both at the same time (in
heating or cooling) will cause discomfort.
Floor circuit is the recommended terminal, as it ensures
the best energy efficiency.
Room temperature control
Different terminals (T1, T2,…Tn) can be placed in a single
room or in multiple rooms.
Each of them can have a thermostat, to stop the terminal
when a certain temperature is reached.
It is possible to control one room with a user interface or a
thermostat connected to the unit. This room should be the
one with the highest heating/cooling requirements.
In this room it is not required to place a thermostat on the
terminal/s.
It is suggested to place a thermostat on terminals placed in
rooms with significantly different thermal requirements.
It is recommended to control the room temperature with
the user interface; this way the control adjusts water
temperature to meet the setpoint, and comfort and energy
efficiency are optimised.
If no user interface is used:
• If thermostats are used, set climatic curves slightly
higher in heat mode and slightly lower in cool mode.
• If no thermostats are used (temperature requirements
should be similar for all rooms), climatic curves must
be set exactly right for both heating and cooling
operation.
