EKRTETS
Room thermostat
4P677096-1 – 2021.10
INFORMATION
The open window function will NOT work in the following
situations:
▪ EKRTETS is installed as floor sensor (parameter 20 –
"rEGU" is set to "FLR").
▪ The room thermostat is in holiday mode or in OFF
mode.
▪ The temperature drops below the anti-freeze
temperature set in the user menu.
▪ The unit operation mode is set to cooling (reversible
mode).
INFORMATION
If enabled, the open window function will still respect the
anti-freeze temperature (parameter 06 – "HG" in the user
menu). This means that the room thermostat will keep
heating to maintain the anti-freeze temperature (by default
10°C).
To enable or disable the open window function
1 Press and hold for 5 seconds.
Result: The first parameter ( rEGU ) of the installer menu
appears.
2 Use and to select parameter 33 ( Win ).
3 Use and to change the parameter value to yes (enabled,
default value) or no (disabled).
4 Press to confirm.
5 Use and to select to parameter 37 ( End ).
6 Press to exit the installer menu.
Result: The open window function is enabled/disabled.
3.3.3 Dew prevention
For reversible systems, the room thermostat offers 2 ways of
managing humidity in order to prevent condensation while cooling.
Humidity percentage threshold
You can set a threshold value for the humidity percentage.
Whenever the room thermostat detects that the humidity percentage
exceeds the set threshold, cooling demand is ceased to prevent
condensation. Whenever this is the case,
blinks on the room
thermostat display. To change the threshold value (default 55%), set
the value for parameter 34 ("
rH ") to the desired value in the installer
menu.
Dew prevention function with floor temperature sensor
If the optional external temperature sensor EKRTETS is installed as
floor temperature sensor, parameter 35 ("
dEv ") can be set to "yes"
in the installer menu to enable the dew prevention function.
When enabled, this function will continuously compare the
temperature measured by the floor temperature sensor against the
dew point. The dew point is calculated based on the room
temperature and humidity. When the floor temperature drops below
or comes too close to the dew point, cooling demand is stopped
temporarily to prevent any condensation on the floor. While the dew
prevention function is active,
blinks on the room thermostat display.
3.4 User menu
The user menu allows you to set basic room thermostat parameters.
3.4.1 To enter the user menu
1 Press and hold for 5 seconds.
Result: The first parameter (rF INI) of the user menu appears on the
display.
To exit the user menu, use the navigation buttons to select the "End"
parameter and press .
3.4.2 To modify parameters in the user menu
Prerequisite: You are in the user menu.
1 Use and to cycle between parameters.
2 Press to select the parameter.
3 Modify the desired parameter using and .
4 After making changes, press to save.
3.4.3 User parameters

(b)
If enabled, this function will activate the installation in advance
(up to a maximum of 2 hours) to ensure that the desired setpoint
is reached at the appropriate time according to the set program.
With every program change, the room thermostat measures the
time taken by the installation to reach the setpoint to compensate
for any temperature differences that may be present at different
times. This allows you to make program changes without needing
to adjust the temperature in advance, because the room
thermostat does this automatically.
