After choosing the required functions, fix the control support bracket that is
included in the delivery on the edge of the internal structure; always remember
to tighten the screw very well. Move the plastic cover up to the external edge
of the plated support
(Fig.1)
.
Insert the terminal board of the control (MC) into the terminal board of the
fan coil (MFC). Take care and tighten the screws of the terminal board.
Any TME minimum water probe must be connected to terminal board J6.
In the case of right water connections, the control must be installed on the
left of the Fan Coil.
In order to carry out this, follow the instructions of
Fig. 2
.
Since we have to change the side of the water connections in yard (possible
only for versions with centrifugal motor), the control must be installed in the
opposite side of the connections.
The connecting terminals, the cables and the fair-lead should
be fixed again on the opposite side, taking care in removing
the pre-sheared from the hole where should be inserted the
fair-lead.
Attention!
With the control unit on OFF,
the fan coil is still supplied with 230 V.
Before carrying out maintenance,
always disconnect from the voltage.

• TECHNICAL CHARACTERISTICS OF THE CONTROL UNIT
1) Power supply: 230V~
2) Thermostat control range from 12 to 32°C with differential 0.7°C
3) 2 x optoinsulated inputs for remote seasonal changeover (IN2); reducing set point reduction or turning off the control unit (IN1)
4) Probe status control: if the air probe is disconnected or short-circuited, the control unit switches to continuous operation (valve outputs energised
and fan on) and the red LED on the front of the control unit starts flashing; in the “automatic summer-winter switching” configuration, the control
unit is disabled and only the LED flashes.
