2. Installation Instructions
-8-
The MTC/SUPER/HU Thermostat designed for flush mounting in the
room to be controlled. It should be located where the occupant can
easily read the display and use the controls.
If the built in temperature and humidity sensors are being used to
measure room temperature and humidity, the panel should be placed
where the temperature is representative of the general room
conditions, away from cold or warm air draughts, radiant heat and
direct sunlight.
The panel should not be installed on an outside wall.
- The standard installation height is 1.5 meter (5 feet) from the floor.
WARNING: Risk of Electric Shock and Property Damage.
Disconnect power supply before making electrical connections.
The installation is to be performed by a qualified electrician.
WARNING: The integrated circuits in the controller are
sensitive to static currents. Take suitable precautions.

2. Installation Instructions (cont’)
-9-
Installation procedure:
1. separate the front display from the back plastic cover by inserting a a
small flat screwdriver into each of the three slots as shown in the
picture and rotating it gently.
2. Remove the front display and keep it in a safe place.
3. Connect the wires as shown in the enclosed wiring diagram. All
terminals accept 1x0.5mm2/24 AWG.
4. If necessary, make changes to the DIP switches position as
explained in this manual.
5. Place the thermostat in the electrical box and tighten up the 2 screws
(Gewiss Box - GW 24 203).
6. Adapt the front frame-panel into its place, by pushing it towards the
wall.
