
Attach the mounting plate above the wall outlet for the
supply line .
Engage and wire the circuit board carrier .
First, hook in the upper part of the clock thermostat on top,
then engage .
Put on the cover .

6
Dismounting the clock thermostat
Using a screwdriver, loosen the front panel at the two side
and bottom openings .
Then release the catches on the left and right and remove
the upper part of the housing .
Loosen the plug-in connectors and press the circuit board
carrier together at the top and bottom .
Remove the circuit board carrier through the front.
4. Connection
Power is supplied via L and N (see technical data); the con-
nection to the boiler is made via a relay contact.
!Disconnect the boiler from mains supply before connec-
ting the thermostat.
!In order to eliminate the possibility of EMC interference,
always lay the mains supply feed separate from the
external input (if one is being used).
!Faulty connections will damage the device.

Connecting clock thermostat and smart-
phone (via app) – pairing
The clock thermostats can be programmed using an app
(from Android 4.3, iOS 5) on a mobile end device. Communica-
tion takes place via Bluetooth BLE.
Download the RAMSES BLE app from the App Store or
Google Play Store
Open the app
▻ Window with ofine mode/assign appears
Press the button on RAMSES BLE for 3 s (green LED at
RAMSES BLE ashes)
Press Assign
▻Device list appears
Select device and press ok
Enter the name for RAMSES BLE (e.g. living room …)
Conrm with ok
▻ RAMSES BLE is now paired. Each time when restarting
the app, a connection will be established. This takes
several seconds (the Bluetooth icon on the top left of
the app ashes)

The created programs are automatically sent to the clock
thermostat.
Creating a holiday program
In order to create a holiday program and activate it,
slide the controller to "Activation"
After a holiday program has been created via the app, the
clock thermostat receives the following information:
– active/not active
– Start date and end date with time
– Room set temperature during holiday time

LThe functions in this submenu have to be set by the quali-
 ed electrician.
In the settings, language, temperature (comfort, eco, frost),
wall compensation, optimisation, etc. can be set.
1. Setting the wall compensation
If the installation location is unfavourable, temperature
deviations between detected and actual room temperature
might occur. This difference can be corrected by using the wall
compensation.

16
2. Setting the controller
Behaviour of a PD controller (pulse duration con-
troller)
With adapted heating systems, a PD controller is characte-
rised by its short transient time, minimal overshoot and high
control accuracy.
– Control period: 5 bis 30 min
– Control range: ± 0,2 K bis ± 5 K
Behaviour of a hysteresis (on/off) controller
In over or undersized heating systems, a hysteresis controller
is characterised by a minimum switching frequency and low
temperature deviations.
– Switching hysteresis: ± 0,2 K bis ± 1 K

3. External input
The external input can be congured for various external
sensors.
!Input is active, therefore do not use external voltage.
The connected contact must be oating and electrically
isolated.
The following options are available with the indivi-
dual sensors/contacts

LIf the external input is set to "oor" or "room temperature", an
appropriate temperature sensor has to be connected. If this sen-
sor is missing, the red LED ashes at one second intervals.

4. Setting the optimisation
The optimisation function allows you to achieve a certain
room temperature at a desired switching point. The display
shows how many minutes earlier the heating starts. This time
applies per K of temperature difference between actual tem-
perature and desired set temperature.
Example
At 06.00 a.m. in the morning, a change in the bathroom is
programmed from reduction (17 °C) to comfort temperature
(23 °C).
Without optimisation function, the room thermostat enables
the heating request for the bathroom at 06.00 a.m. Depen-
ding on the size of the room and the installed heating system,
the bathroom reaches the desired 23 °C at 6.30 a.m., for
example.

19
With a set optimisation of 5 min/K, the thermostat sends the
heating request earlier, as follows:
Set temperature at 06.00 a.m.  23 °C
Actual temperature  17 °C
i.e. Delta T = 6 K
6 K * 5 min/K = 30 min
The controller sends the heating start 30 min. earlier and
reaches the setpoint temperature at 06.00 a.m.
LThe optimisation value depends on the spatial and heating
conditions.
5. PIN
This function can be used to assign a new PIN.
•The factory setting for the PIN is 0.
•New PIN can be entered (1–6 digits).
•In case of Delete pairing (2nd pairing), the PIN is set to
0.
•If the PIN is 0, the PIN will not be requested during
pairing.
