Review of the thermometer sensors
Figure 2: 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 at the fan (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 panel can show 2 lines of text with each 8 characters.
The upper line shows a guiding text.
The bottom line shows the matching values to the guiding text.
The text in the display in “on” as long as there is power to the unit and will not turn off even though

How to use the menu:
It is possible to adjust a value or a function by finding the matching menu via por q.
To activate the desired menu press ENTER.
To adjust the settings of the value press ENTER until the value flashes.
The adjustment can now be done viapq.
To save the chosen value press ENTER.
It is advisable to have the panel and/or the review of the menus near by during the reading of the

The menu CUSTOM OPTIONS overrides the operating mode of the main menu by activating an
external switch.
There are four custom options: ”exhaust” and ”inlet”, ”extend” and “OFF”
”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.
Options that flash are indicated by ” ”.

Night Cooling
The NIGHT COOLING menu makes it possible to select passive night cooling, provided that the
outdoor temperature on the day before has exceeded the day temperature limit set in the NIGHT
COOLING menu for at least one hour.
During the night cooling period, the compressor cooling is suspended and the room setpoint is
lowered to the temperature set in the NIGHT COOLING menu.
The limit set for the minimum intake temperature is not observed during night cooling, but the sys-
tem may run compressor heating if the room temperature falls below the night cooling setpoint.
No special account is taken of whether the room temperature is above or below the outdoor tem-
perature, i.e. whether a cooling effect from the outdoor air can actually be achieved.
When the night cooling period is over, the system will run as normal again, with compressor heat-
ing and cooling according to the normal setpoint.
