Description

The Symondo Box is a universal heating and zoning controller for surface heating and cooling systems. It can be used in combination with Symondo Controller to efficiently control the function of your surface heating and cooling systems with intuitive operability. The inputs and outputs can be assigned freely via Symondo Controller, allowing for the implementation of different heating and cooling systems.

Important characteristics of the Symondo Box include:

• Control of 8 heating and cooling zones with 1-4 thermostatic radiator valves each
• Measurement of room temperature and humidity in combination with Symondo Controller, Symondo Sensor or Room sensor
• Optionally weather compensated via an external temperature sensor
• Optional control of heating circuit pump and mixer (PWM or 0-10V) possible
• 2 separate CAN bus interfaces for building network and private floor or apartment network
• Connectable with other MULTIBETON products via CAN bus
• Control of mixers, valves, and energy generators via 0-10V / PWM
• 2 additional floating changeover contacts (terminals J and K) for flexible assignment with additional functions

Safety Instructions

• The controller does not replace safety appliances on site.
• Temperature values set too high can lead to scalding or damage to the system. Scalding protection must be provided by the customer.
• Temperature sensor cables must be routed separately from mains voltage cables.
• The controller should only be installed in dry areas under ambient conditions described in Specifications.
• Low-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.

General

• By no means does the controller replace the safety appliances on site!
• Temperature values which are set too high can lead to scalding or damage to the system. Scalding protection must be provided by the customer!
• The 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

• Install the controller only in dry areas and under the ambient conditions described in “Specifications”.
• Low-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 Instructions

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 pressing it down. Ensure that the locking catches engage completely and that the device is firmly seated on the rail.
3. If terminal blocks (B-I) are to be supplied with a voltage other than mains voltage, proceed as follows:
4. Remove existing bridges A1 – B1 and A2 – B2
5. Insert a separating wall between A – B
6. Connect the power supply to B1 (L) and B2 (N)
7. Observe max. switching power of relay and fuse (4AT)
8. For heating zones with 230 VAC actuators, use a bridge. For heating zones with e.g. 24 VAC actuators, use a separation wall.
9. The separation walls and cover can be removed for easier connection of cables. They must then be reinstalled to safely separate areas carrying mains voltage from areas carrying low voltages.

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 attachment 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)
