Floor heating limitation function (RDE100.1 only)
The factory setting for this function is Off (disabled) and must be set to "On" if floor
heating is used.
The external floor temperature sensor is connected to input X1, and acquires
the floor temperature. If the floor temperature exceeds the parameterized
temperature limit xx ºC (P14 = 1, P15 = 1, P16 = xx ºC), the heating valve is fully
closed until the floor temperature returns to a level below the parameterized limit.
Typical application is rooms (dry floor).
If the application does not require floor heating temperature limitation but instead
uses the external sensor as a source for both room temperature display and
control, the parameters will have to be set as follows: P14 = 1, P15 = 0. A typical
application is the bathroom (wet floor) where a constant floor temperature is
required.
It is not recommended to have only an internal built-in room sensor for floor
heating since there is a potential risk of overheating.
Operating mode switchover function
This function allows keycard application, please refer to the section “Operating
notes, Economy mode”.

Mounting and installation notes
Do not mount the thermostat in niches or bookshelves, not behind curtains, not
above or near heat sources, and not exposed to direct solar radiation. Mount about
1.5 m above the floor.
Mounting •Mount the thermostat in a clean and dry location without direct air flow from a
heating/cooling equipment, and not exposed to drip or splash water
Note: When RDE100.. is equipped with either China 86 conduit box or BS4662
UK conduit box, ARG70.5 adapter plate is suggested to provide a better fitting
installation.
Wiring See Mounting Instructions M1429 enclosed with the thermostat.
•Ensure that wiring, protection and earthing comply with local regulations
•Correctly size the cables to the thermostat and the valve actuators
•Use only valve actuators rated for AC 24…230 V
Warning!
No internal line protection for supply lines to external consumers.
Risk of fire and injury due to short-circuits!
•Adapt the line diameters as per local regulations to the rated value of the
installed overcurrent protection device
•The AC 230 V mains supply line must have a circuit breaker with a rated
current of no more than 10 A
•Disconnect from power supply before removing the unit from its mounting plate
•External Inputs X1, may carry mains potential. Sensor cables or window
contact must carefully install before powering up the thermostat
Commissioning notes
After power is applied, the thermostat carries out a reset during which all LCD
segments flash, indicating that the reset was made correctly. After the reset, the
thermostat is ready for commissioning by qualified HVAC personnel.
The control parameters of the thermostat can be set to ensure optimum
performance of the entire system. Please refer to Operating Instructions
CB1B1422, section "Do you want to change parameters?".

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.)
If the battery symbol appears, the batteries are almost exhausted and should
be replaced. Use alkaline batteries type AAA.
Operating notes
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 appears on the display. The setpoint
(20 ºC) can be readjusted by pressing touchkeys +and –.
When Economy mode is activated, symbol appears on the display. The setpoint
(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, . Depending on whether the window contact is
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).
