General notes
This manual contains basic instructions and important information about safety, installation and operation. Before com-
missioning and operation, the installer/specialist and the operator of the system have to read the manual completely. It
is an automatic electric temperature controller for household and similar applications. In addition, observe the accident
prevention regulations applicable in the respective countries, the applicable standards and regulations and the install-
ation and operating instructions for additional system components. Installation, electrical connection, commissioning
and maintenance may only be carried out by specialists who possess the appropriate training. Users: Make sure that
the specialist gives you detailed information on the function and operation of the controller.

LED status
LED A Lights up, if mains voltage is present and relay A is switched.
LED B - K Lights up, if relay B - K is switched
LED L Lights up, if the private CAN bus is active.
Flashes with 1Hz (60x / minute) if there is an error in the private CAN bus.
LED N
Lights up if the building CAN bus and the 1-wire bus are active.
Flashes with 1Hz (60x / minute) if there is an error in the building CAN.
Flashes with 3Hz (180x / minute) if there is an error in the 1-wire connection. EXCEPTION: If the building CAN
bus remains unused, a flashing of the LED M is normal and does NOT mean that there is a error.
LED N Lights up, if outputs V1, V2 or V3 are active.

Instruction Manual
Description
The Symondo Box is a universal heating and zoning controller for Surface heating and cooling systems. In combination
with Symondo Controller, this enables efficient use and function control of your surface heating and surface cooling
with intuitive operability. The inputs and outputs can be freely assigned via Symondo Controller, so that different heat-
ing and cooling systems can be implemented.
Important characteristics of the Symondo Box:
lControl of 8 heating and cooling zones with 1 - 4 thermostatic radiator valves each
lMeasurement of room temperature and humidity in combination with Symondo Controller, Symondo Sensor or
Room sensor
loptionally weather compensated via an external temperature sensor
loptional control of heating circuit pump and mixer (PWM oder 0-10V) possible
l2 separate CAN bus interfaces for building network and private floor or apartment network
lconnectable with other MULTIBETON products via CAN bus
lControl of mixers, valves and energy generators via 0-10V / PWM
l2 additional floating changeover contacts (terminals J and K) for flexible assignment with additional functions
Safety Instructions
General
lBy no means does the controller replace the safety appliances on site!
lTemperature values which are set too high can lead to scalding or damage to the system. Scalding protection must
be provided by the customer!
lThe temperature sensor cables must be routed separately from mains voltage cables, and must not, for example,
be routed in the same cable duct!
Wall Installation
lInstall the controller only in dry areas and under the ambient conditions described in “Specifications”.
lLow-voltage cables such as temperature sensor cables must be routed separately from mains voltage cables. Feed
temperature sensor cables only into the left-hand side of the unit, and mains voltage cables only into the right-hand
side.
Wall Installation
Fix the DIN rail horizontally to the wall using screws.
Installation
1. Place the Symondo Box on the upper edge of the DIN rail
with the locking catch on top. 2. Engage the device by press-
ing it down. Ensure that the locking catches engage com-
pletely and that the device is firmly seated on the rail.
Disassembly
Remove the Symondo Box from the DIN rail by inserting two
screwdrivers into the eyelets and pulling them down-wards.
Separation walls and cover
The separation walls and the cover can be removed for easier
connection of the cables. They must then
be rein-stalled in order to safely separate areas carrying
mains voltage from areas carrying low voltages.
Open the cover (90° degree) and then pull it out of the attach-
ment laterally.
If the terminal blocks (B-I) are to be supplied with a voltage other than the mains voltage,
proceed as follows:
1. Remove existing bridges A1 - B1 and A2 - B2
2. It is absolutely necessary to insert a separating wall between A - B.
3. Connect the power supply to B1 (L) and B2 (N).
4. Observe max. switching power of relay and fuse (4AT)
