If the temperature on the display does not agree with the room temperature
effectively measured, the temperature sensor can be recalibrated. For that
purpose, adjust parameter P04.
We recommend reviewing the setpoint lock (for public areas) in parameters P06
and P08 and changing them as needed.
Since the thermostat uses touch technology and to minimize battery power
consumption, a parameter P21 (adjustable from 0.25 to 1.5 seconds) is
implemented for the user to adjust. This function is only valid for the battery-
powered version and the default value is 1 second.
This means that when, for a certain time, the user does not touch the touchpad, the
unit operates in power saving mode and the touchpad is running at a scanning rate
of 1 second.
(From the calculation – assuming 4 operations per day on the thermostat, the
estimated 1-second scanning rate results in a battery life of 1 year. If the user
increases the scanning rate, the batteries' life is extended.)

The RDE100.. provides Comfort, Economy, Auto timer and Protection mode. The
difference between Comfort and Economy mode is only the room temperature
setpoint. The changeover between Comfort, Economy and Protection mode is
made either automatically by the auto time switch or by pressing touchkey mode.
When Comfort mode is activated, symbol
(20 ºC) can be readjusted by pressing touchkeys + and –.
When Economy mode is activated, symbol
(16 ºC) can be readjusted by pressing touchkeys + and –.
In RDE100.1, a window contact feature is that a user can connect a window
contact to the input X1,
configured to Normally Open or Normally Close (Parameter P14 = 2, Parameter
P17 = 0 or 1), a change in this status will automatically switch the thermostat from
any modes to Economy mode. This feature is good for public area. The factory
setting for this function is Off (disabled).
If the temperature falls below 5 ºC, the unit automatically activates the heating
output. The symbol
appears only, if the icon is enabled via parameter settings.
When Auto timer mode is enabled, the changeover between the operating modes
(Comfort and Economy mode) will take place automatically. There are three
options for time switch setting: individual day, 7 day or 5-2 day. You can select
Comfort or Economy mode in every 15 minutes interval of the day. The 0:00 to
24:00 hour time bar will allow you to set the mode throughout the selected day(s).
