Review of the thermometer sensors
Figure 1: Thermometer sensors
Explanation for figure 2:
T1
- is the thermometer sensor for the fresh air and should be placed at the north side of the
building.
T2 - is the thermometer sensor for the inlet air(without heating surface).
T5 - shows the temperature of the condenser.
T6 - shows the temperature of the evaporator.
T7 - is the thermometer sensor for the inlet air after a heating surface.
T10 - is the thermometer sensor for the exhaust air in a room (accessory).
T15 - is the thermometer sensor in the CTS 602 panel.
The temperature of the sensors can be read in the “Show data” menu.

The menu CUSTOM OPTIONS overrides the operating mode of the main menu by activating an
external switch.
”VENTILAT”: There is a possibility here to run with a higher or lower speed on the air exhaust and
air inlet for a limited amount of time. The external pressure will activate the function. The function
has high priority.
”exhaust” and ”inlet”: These two options increase or reduce the velocity of the exhaust or inlet air
respectively for a limited period of time. The remaining functions of the operating mode remain
unaltered. An external switch activates the timer function.
Another external switch ensures that the fans remain at the desired ventilation level until the switch
is turned off.
”extend”: This option controls the velocity of the exhaust and inlet air and can be used to change
the temperature of the inlet air for a limited period of time. An external switch activates the timer
function.
“OFF”: Deactivates the external switch.
”ext offs”: Provides the possibility of choosing an afterflow time and changing the set point in external rooms.
