Range: 0...10 Hours
Note: Set “0” to disable the timer.

Economy mode can be activated by triggering a window contact,
door switch, key-tag or PIR sensor.
When Economy mode is active, the thermostat will either turn off or
use special economy set points for cooling and heating set by
technician.
Please refer to parameters P25 and P26 in the technician setting
section of this manual.
The following indications will appear on display:
-E1 – Economy mode triggered by window contact
-E2 – Economy mode triggered by PIR (occupancy sensor)
-E4 – Economy mode triggered by door switch or key-tag
-E5 – OFF state triggered by door switch or key-tag

Normal work Freeze protection
Cut-in
Cut-out
The Freeze protection feature will not allow the room temperature to
drop below predefined cut-in temperature. Depending on which
configuration the system is operating under (with or without Heat pump)
this feature will force the system to operate in heat mode and activate
the fan.
This feature will take effect when the thermostat is either ON or OFF.
When the room temperature rises above the predefined cut-out
temperature, the thermostat will return to its previous state.
When freeze protection is activated, the display alternates between
“AL” and room temperature.
For selection of cut-in and cut-out temperatures, please refer to
technician settings parameters P36 and P37.

1.11 Freeze protection

The thermostat continuously monitors the ambient CO2level using the
built in CO2sensor and compares the readings to the CO2set-point.
When the ambient CO2level rises above the set-point, the fresh air
damper will open to bring in fresh air.
Additionally, when the ambient CO2level exceed the high limit alarm,
an indication will appear on the display.
The values of the CO2set-point and high limit alarm, together with
other CO2parameters are set by technician.
Please refer to parameters P180-P185 in the technician setting section.
All CO2parameters and readings can be monitored through BMS and
optionally trigger other air handling devices to take action.
The CO2ambient reading can either be displayed constantly or hidden
by setting either “0” or “1” to technician parameter P180.
Important: Please allow 12 hours of operation from initial power up,
before reading a reliable CO2value.

2. Installation Instructions
-10-
The MTS/SUPER/CO2 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 sensor is being used to measure room
temperature, 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’)
-11-
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 Europe - Gewiss Box - GW 24 203 or similar
US - Carlon – B114R or similar or similar
6. Adapt the front frame-panel into its place, by pushing it towards the
wall.
