Commissioning notes

Touchpad scanning
rate

After power is applied, the thermostat carries out a reset during which all LCD
segments flash, indicating that the reset is correctly made. 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 (refer to Operating Instructions CB1B1424en,
section "Do you want to change parameters?").

If the temperature shown 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 to review the setpoint setting range and setpoint lock (for public
spaces) using parameters P05…P08 and change them as needed to achieve
maximum comfort and energy savings.

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 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.)

Change of batteries

LED indication on
RCR100RF

If the battery symbol appears, the batteries are almost exhausted and should
be replaced. Use alkaline batteries type AAA.

For the pairing process between transmitter and receiver, refer to Operating
Instructions CB1B1424en, section "Do you want to pair transmitter and receiver?".
The table below describes the behavior of the RCR100RF:

State of receiver State of LED

Power up (or reset) The red and green LEDs flash alternately for 5

seconds and then change to constantly red.
Note: If the receiver was programmed before, it
will immediately change to constantly red.

Learning mode

Successful learning mode

The red and green LEDs flash alternately.

If learning was successful, the green LED will
flash for 10 minutes.

Signal ok and output status
change

The green LED is lit. If the output state changes,
the green LED flashes for 3 seconds and then
changes back to constantly green.

Fails to receive wireless data If the RCR100RF fails to receive wireless data,

the red LED will start to flash after 125 minutes.
If the RCR100RF signal is recovered, it will
resume the previous LED state.

Operating notes

The receiver provides an override function (boiler test, emergency operation). It
allows the installer to override the relay to be permanently energized, regardless of
the wireless data received.

To activate the override function, press and hold the button for at least 10
seconds and release. The LED is constantly green and off once every 5 seconds,
indicating that the override function is enabled.

To disable the override function, press the button once.

The RDD100.1RF provides Comfort, Economy 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 by pressing touchkey .

Comfort mode

Economy mode

Maintenance notes

Disposal

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 thermostat automatically activates the
heating output. Symbol appears only if the icon is enabled via parameter
settings.

Thermostat and receiver are maintenance-free.

The device is considered an electronic device for disposal in terms of the
European Directive 2012/19/EU and may not be disposed of as domestic
garbage.

∂ Dispose of the device through channels provided for this purpose.
∂ Comply with all local and currently applicable laws and regulations.
∂ Dispose of empty batteries in designated collection points.
