Connection - DELTA DORE DELTA 200 Installation Manual

Connection

The diagrams provided are simplified for greater clarity.
Protections and other accessories required by standards are not illustrated.
- The connection must comply with UTE standard NF C15-100 and good practice.
- Nearby units or those that are connected must not generate excessive interference
(directive 2004/108/EEC).
• The contact sensor cable is 2.5 m long.
• The outdoor sensor can be connected using Ro2V cable (1.5 mm2).
• Sensor cables must never be longer than 50 m.
• Use an optional rate 3-way mixer valve, equipped with a 24 V or 230 V
servomotor. Duration of travel: 60 sec. to 240 sec.

IMPORTANT :
- Before connecting the return sensor for network 2, remove the resistor wired to terminals 3 and 4.
- To prevent any confusion when connecting the bus, it is advisable to use a cable of a completely
different colour from that used for the unit's power supply (take care to align the poles properly).
- Any junctions or terminal block connections must be made outside the unit.
- The underfloor heating system must have a safety device that automatically cuts off the supply
of heat to the underfloor heating system when it reaches the limits set by DTU standard 65.8.
This underfloor heating security thermostat must be connected in series to the zone 1 circulator.
- In this wiring example, the mixer valve is supplied with 230 V power.
Some valves may be supplied with 24 V power. If this is the case, you must modify the wiring.

The wiring for the boiler thermostat input
control is optional.
It must be connected if you wish to authori-
se reductions when the DELTA 200 is not
being used for heating.
To connect it, remove the shunt (electric
wire) connecting the two thermostat input
terminals.
If the boiler has a clock input, do not mistake it for the thermostat input.
Testing the installation
Before closing the cover of the technical unit:
- Switch the installation on,
- Check that the green LED comes on (dialogue between the technical
unit and the room unit),
- Use a temperature setting that is high enough to activate the heating,
- The red LEDs indicate the status of the relay outputs:
