Installing the room unit

Choosing a location

Since the temperature measurement sensor is inside the unit, you must

install the thermostat flush-mounting box:

- in zone 1 (main room) only,

- on an accessible wall at a height of 1.50 m,

- away from heat sources (fireplaces, sunlight) and draughts (windows,

doors).

IMPORTANT: Do not install the thermostat on a wall in contact with the out-

doors or with an unheated room (e.g. garage, etc.).

The sleeve output in the flush-mounting box must be plugged (with mastic)

in order to avoid unwanted air movements that would cause the sensor rea-

ding to be inaccurate.

Installing the sensors

Feed (zone 1) and return (zone 2) sensor

The water temperature sensors are wall-moun-

ted.

They are used to measure the surface tempera-

ture of pipes..

They can be used in a measurement range of -

30°C to +150°C, and are fitted as standard with

a 10 kΩNTC measuring element.

The sensors have a clamp so that they can be attached to pipes up to 1½"

in diameter.

The feed sensor (zone 1) must be installed after the mixer valve, between

the circulator (~50 cm) and the connected equipment (underfloor heating or

radiators).

The return sensor (zone 2) must be installed on the return of

the direct radiator network.

To ensure that the temperature is measured correctly, apply

the thermal paste from the syringe between the sensor and

the pipe.

Outdoor sensor

The outdoor sensor must be attached to a vertical wall with

screws and plugs.

The recommended position is on a

wall facing north or north-west,

away from unwanted heat sources (fireplace, air

vents, thermal bridges, etc.).

Mounting the room unit

Switch off the mains power supply (general

circuit breaker) before proceeding.

To attach the unit to the wall, you must separate it

from its base.

To do this, unscrew the lock screw as shown

opposite.

Once separated from the unit, the base can be

connected to the technical unit via the bus,

then attached to the flush-mounting box (dis-

tance between centres: 60 mm).

Screw the unit

closed.

Mounting the technical unit

The technical unit must be installed next to the boiler.

Remove the cover and attach the unit using screws and plugs.

Connect the unit before closing the cover.

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:

- Restore the settings required for normal use,

- Close the cover of the technical unit.

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.

IMPORTANT: If you are using underfloor heating, the temperature

must not exceed 50°C.

When you increase the maximum temperature of network 1 from 50 to

51°C, network 1 acquires the status of a radiator network:

- zone 1 automatically goes into Comfort mode from 6am to 11pm for

each day of the week,

- the slope of zone 1 is initialised at 2.

When you decrease the maximum temperature of network 1 from 51 to

50°C, network 1 acquires the status of an underfloor heating network:

- zone 1 automatically goes into continuous Comfort mode for each day

of the week,

- the slope of zone 1 is initialised at 0.8.

Menu C07: Setting the slope of zone 1 (see pg. 14)

Default setting: C07=0 and the slope is set to 0.8.

Example 1: Setting network 1 for underfloor heating

To determine the correct slope for your installation, on the corresponding

axes, note down the maximum feed temperature for network 1 (set in menu

C04, e.g. 45°C) and the minimum outdoor base temperature (e.g.-6°C). In

this example, the correct slope is 0.9.

Example 2: Setting network 1 for radiators

On the corresponding axes, note down the maximum feed temperature for

network 1 (set in menu C04, e.g. 75°C) and the minimum outdoor base

temperature (e.g. -6°C).

In this example, the correct slope is 2.

IMPORTANT: In a few days (if the programming authorises enough com-

fort periods), DELTA 200 will automatically adapt the slope to the installa-

tion settings: this is self-adaptation.

Menu C08: Setting the slope of zone 2

Default setting: C08=0 and the slope set is 1.0.

Example: Minimum outdoor base temperature: -6°C

Direct radiator network feed temperature: 70°C

Determine the temperature drop (Δt) between the network feed and return

in accordance with the installation characteristics: e.g. 20°C

In this example, the return temperature is estimated to be 50°C.

On the corresponding axes, note down the maximum return temperature for

network 2 and the minimum outdoor base temperature (e.g. -6°C).

In this example, the correct slope is 1.

Manual setting:

Set the temperature to 20°C on the DELTA 200 and set

the thermostatically controlled valves to maximum.For outdoor temperatu-

res of around 10°C, you must obtain 20°C in the room measured.

Use a higher slope if the temperature is lower.

Use a lower slope if the temperature is higher.

Return the thermostatically controlled valves to the desired setting.

Changes not allowed

Changes allowed (from 0 to 4 in increments of 0.1)

Menu C11: Setting the temperature increase time for

zone 2

This is the period during which overpower is used in zone 2 to increase the

temperature.

The following formula is used when switching from Economy to Comfort

mode: Toverpower = setting C11 x (zone 2 setting - outdoor T°)

The following formula is used when switching from Shutdown or Frost

Protection to Economy or Comfort mode:

Tsoverpower = 2 x setting C11 x (zone 2 setting - outdoorT°)

Upon activation, the time is set to 5 min./°C.

Menu C12: Control differential for zone 2

Default setting: C12=0 and the differential is set to 3°C.

Tip: Initially, use the default setting (30 min/°C).

- If the desired temperature is reached too quickly, set a higher value

(e.g. 45 min./°C).

- If the desired temperature is not reached quickly enough, set a lower

value (e.g. 20 min./°C).

IMPORTANT : If you do not require anticipation, set C10 to 0.

Menu C9: Valve operating time

Corresponds to the maximum time for the valve to open or close.

Default setting: C09=0 and the time set is 120 seconds.

Menu C10: Anticipation value of zone 1

Anticipation is the time it takes to reach the desired temperature at the time

specified in the program, namely:

Tanticipation = (Zone 1 setting - Zone 1 T° as measured) x Setting C10.

It keeps the temperature from rising too quickly, which would consume too

much energy.

Example:You are in economy mode and the room temperature is 17°C.

The Comfort temperature setting is 20°C.

C10 is set to 30 min/°C.

For room temperature to have reached 20°C by the time Comfort mode is

programmed to come on, heating will need to begin 1.5 hours in advance:

Ta = (20°C - 17°C) x 30 min./°C = 1:30.

Default setting: C10=0 and anticipation time is set to 30 minutes/°C.

Changes not allowed

Changes allowed (from 0 to 120 minutes/°C in increments of 5)

Upon activation, the time is set to 30 min./°C.
