INSTALLATION AND CONNECTION OF N-THC ROOM CONTROL UNITS

U I A

The  N-THC  room  control  units  can  manage  up  to  two  zones,  controlling  temperature  and  humidity  according  to  the  selected
configuration; see the diagrams below.

Installation instructions

The room controller must be installed in the best reference
position for temperature control.
Position the room controller as follows:
• around 1.5 metres from the floor, in a part of the room that

allows the sensor to accurately measure the room temper-
ature;

• away from cold air flows, sunlight or other sources of heat.
• leave  enough  space  above  the  room  controller  to  allow

assembly and removal where necessary.

• If the room controller is removed from its base, it discon-

nects  from  the  power  supply  and  consequently  is  no
longer operating.
