Periodic pump run function
Can only be used when circulating pump or valve is controlled!
This function protects the pump or valve against seizing during longer off periods.
Perodic pump run is activated for 3 minutes every 24 hours at 12:00.

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
Wiring See the Mounting Instructions M1429 enclosed with the thermostat.
•Ensure that wiring, fusing 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
•The AC 230 V mains supply line must have an external fuse or circuit breaker
with a rated current of no more than 10 A
•Disconnect from power supply before removing the unit from its mounting plate
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 perform-
ance of the entire system. Please refer to Operating Instructions CB1B1423, sec-
tion "Do you want to change parameters?".
If the temperature on the display does not agree with the room temperature effec-
tively 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 con-
sumption, 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 esti-
mated 1-second scanning rate results in a battery life of 1 year. If the user in-
creases 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 RDE100.1DHW 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 –.
If the temperature falls below 5 ºC, the unit automatically activates the heating out-
put. The symbol appears only, if the icon is enabled via parameter settings.
When holiday mode is activated, symbol appears on the display. The setpoint
(12 ºC) and the number of days a user is away can be readjusted by pressing
touchkeys + and –.
When Auto timer mode is enabled, the changeover between the operating modes
(Comfort and Economy mode) will take place automatically. There are three op-
tions for time switch setting: individual day, 7 day or 5-2 day. You can select Com-
fort 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).

symbol will be shown. Press this touchkey one more
time, DHW heating will be switched off and no symbol will be shown.
Please refer to Operating Instructions CB1B1423, section "Do you want to activate
DHW control?".
During auto status, the DHW will switch according to the DHW time switch set.
DHW can be selected on or off in every 15 minutes interval of the day. The 0:00 to
24:00 hour time bar will allow you to set DHW on or off throughout the selected
day(s).
