3.1 MasterAria and accessories
Below is a description of the family of devices made up of MasterAria and
its accessories:
Electrical panel
• CTEM7*: Single-phase version
• CTEDB*: Three-phase version
The electrical panel contains the main control board plus the expansion
board with 2 x 0 to 10 Vdc outputs and 2 relay outputs. It is also fi tted with
a disconnect switch, a power contactor for the fan and a circuit breaker
Fig. 3.a
MasterAria main control board (code HYCT000000)
Manages the fan and controls the temperature. Allows the connection
of digital inputs for the remote control of functions such as ON/OFF,
cooling/heating, economy (see sleep function) etc. Fitted, using the
special accessory, with a serial port for the network connection of a
series of units (supervisory system).
Fig. 3.b
Expansion board with analogue/relay outputs (code
HYVC000V00)
Allows MasterAria to control two actuators with 0 to 10 Vdc inputs (e.g.:
modulating valves, etc.) and control any additional loads using to the two
multifunction relays.
Fig. 3.c
Expansion board with 4 relays (code HYVC000R00)
Allows MasterAria to manage ON/OFF actuators (valves, heaters, dampers)
and the hot and cold water signals to the chiller and heat pump/boiler).
Fig. 3.d
Expansion board with 2 triac/relay outputs (code
HYVC000M00)
Allows MasterAria to control loads with a high number of operations (e.g.:
modulating 3 point valves, etc.) using the 2 triac outputs with voltage
signal (230 Vac) and directly control a 2 kW heater. A second multifunction
relay is available for any additional loads.
Fig. 3.e
Expansion board with 4 triacs (code HYVC000T00)
Allows MasterAria to control loads with a high number of operations (e.g.:
modulating 3 point valves, etc.) using the 4 triac outputs with voltage
signal (230 Vac).
