Proper use
The heating controller RAMSES 856 top OT consists of the OT-Box
RAMSES top2 OT as well as the room thermostat RAMSES 850 top2
OT, which transmits the values (target/actual values) via the Open-
Therm bus. The 7-channel regulator regulates 2 heating circuits
with the required circulation pumps and temperature sensors. In ad-
dition, the domestic hot water circulation is maximised via program
control with optional legionella protection function. The range of
functions can be extended via connection of 2 OT boxes.
• The device is intended for wall installation in the boiler room
• Corresponds to Type 1 B in accordance with IEC/EN 60730-1
• The entire system serves the purpose of digital heating
regulation for time-dependent monitoring and control of room
temperature (by means of circulation pumps, burner and/or
motor mixing valve)
• It is used in dry rooms with normal levels of domestic cleanliness
• The controller is suitable only for the Heating-
systems listed. For use in connection with other
systems, contact the service department of Theben AG
• Accessories: optional: RAMSES 850 top2 OT ( (8509132),
feed temperature sensor (9070371), plunge sensor (9070379),
floor sensor (9070321), external temperature sensor (9070459),
additional OT box for system 5 (standard box 9070712)

turning the bayonet socket 90° anti-clockwise.
Attach base of the OT Box RAMSES top2 to the wall
with enclosed material.
Click terminal into the terminal support and connect cable
with the OT connection terminals.
Power supply line of the OT bus, attach the outputs and
sensors in accordance with the selected connection diagram
to the connection terminals of the base (see connection
diagram on page 9).
3
Put on upper part of the OT-Box RAMSES top2 OT, click in
and secure with bayonet socket.
Afterwards optionally click in baffle or RAMSES 850 top2 OT
in opening.
Connect OT-Box RAMSES top2 to power supply.
Dismantling
Remove RAMSES 850 top2 OT or screen.
Use a screwdriver to unlock upper part, remove and
open device. If necessary take base from wall.

Systems/Applications 1–5
•For the systems or applications 1-4 the OT-Box RAMSES top2
OT is required. The OpenTherm bus links RAMSES 850 top2 OT
with the OT box RAMSES top2 OT.
•System 5 requires 2 OT boxes (centre box and end box),
which are linked via the OpenTherm bus. RAMSES 850 top2
OT as well as both boxes are linked with one another via the
OpenTherm bus. The centre box must be linked to the 0–10 V
(terminal 15 - 15) input with a wire bridge.
With the RAMSES 856 top2 OT an additional OT box (standard
box 9070712) will be required for this system.

e.g. PIN:1234 Set:21.0 (note format!!)
The USB/GSM modem sends an SMS with:
PIN:Ok Set:21.0 Temp:19.0
To query the current temperature and settings,
send the PIN number to the USB/GSM modem:
e.g. PIN:1234
The USB/GSM modem sends an SMS with:
