Display ‘DC60’ 1

1.1 Introduction

The display ‘DC60’ is customized for the user.
It allows an overview of the operation of the Unit and allows access to some parameters.

Depending on the setting in the Climatic, two display configurations are possible:

• Mode ‘Light’

• Mode ‘Full’

The 'DC60' is designed to be remotely connected of the Unit.

The 'DC60' is equipped with a temperature sensor.
The temperature sensor allows the acquisition of room temperature to control.

1.2 Temperature measurement

All Lennox Unit comes with a temperature sensor; it must be placed in the conditioned area.
But if the 'DC60' is placed in the area conditioned by the Unit, it is possible, in this case, to use the temperature
measurement of the 'DC60'.

DC60, Installation 4

The 'DC60' has been designed for flush mount assembly, on distribution boxes compliant with the standards in force.

4.1 Connection

WARNING: Separate as much as possible probes, displays, logical input cables
from power cables with strong inductive load, in order to avoid possible
electromagnetic perturbations.

4.1.1 Important warning

An error connecting to the display immediately causes the deterioration of this one

or BM60.

Any wiring modification on the CLIMATIC 60 must be done by Lennox technician or employees having valid
electrical qualification and authorization.

DC60-DM60-ROOFTOP-IOM-1310-E - 26 -

4.1.2

The power of the 'DC60' can be 24Vac (+10…-15%) 50/60Hz or 24Vdc (22…35Vdc), maximum current of 2VA.

Lennox recommends a 24Vac supply (provided by Unit) for installation of the display less within 30 meters of Unit.
For connection of the display of over 30 meters, a power supply, close to the display, 24Vac must be provided by the
installer.

For an external connection to the Unit (24V) using a transformer class 2 under 0.1A

For any modification of wiring on the 24V supply or on 4-20mA sensor, check the polarity prior to apply the power.
Wrong polarity may cause serious damage and destroy the Plan network. Lennox will not accept liability for
damage caused by wrong power connection or any wiring modification done by people without valid training and
qualifications.

4.1.3

The 'DC60' is controlled by a communication bus: RS485 2 wires.

4.1.4

The connection of power and communication must be made by the following cable:

- LiYCY-P (0.34 mm ²), 2 pairs with general shield.
The cable length, with power, should not exceed 30m.
The cable length without power (24V external) must not exceed 150m.
For a better electromagnetic protection, Lennox recommends the use of LiYCY-P cable

For extended networks fit a 120 Ohm resistor (R2) between RX/TX+ and RX/TX- on the last device, to avoid possible
communication problems.

4.2 Ferrites Protection of Displays

To prevent radio interference that may cause miscommunication or destruction of elements on the screen, you need
to equip each end of the cable a ferrite (supplied by Lennox).

4.3 Temperature Sensor

All Lennox Unit comes with a temperature sensor; it must be placed in the conditioned area.
But if the 'DC60' is placed in the area conditioned by the Unit, it is possible, in this case, to use the temperature
measurement of the 'DC60'.

To indicate the Climatic™60 your choice, set the point 3213:

- ‘128' to use the measure of the 'DC60'

- ‘1 BM-B12' or '2 BM-B1' to use the remote probe

Note:

- - For Unit with a 'medium' Climatic™60:

Connect the remote sensor between points B12 and GND, terminal block J18.

- - For Unit with a 'small' Climatic™60:

By default the Climatic™60 control the temperature measurement of return. If you want to control on a
measure of room temperature, disconnect the return probe between points B1 and GND, terminal block J13.
Connect the remote sensor in place.

4.4 Configuration

For communicate with the Climatic™60 this basic parameters of internal ‘DC60’ must to be settled.

5.1 Connection

WARNING: Separate as much as possible probes, displays, logical input cables
from power cables with strong inductive load, in order to avoid possible
electromagnetic perturbations.

5.1.1 Important warning

An error connecting to the display immediately causes the deterioration of this one

or BM60.

Any wiring modification on the CLIMATIC 60 must be done by Lennox technician or employees having valid
electrical qualification and authorization.

5.1.2

The 'DM60' is powered by the BM60.

5.1.3

The 'DM60' is controlled by a communication bus: RS485 2 wires.

5.1.4

The connection of power and communication must be made by the following cable:

- For a length of 0 to 300m: AWG22 (0.34 mm ²), two crossed pairs with screen.

- For a length of 0 to 500m: LiYCY-P (0.34 mm ²), two pairs shielded general.
The cable length should not exceed 500m.
For better protection of electromagnetic disturbances Lennox recommends the installation of cable LiYCY-P

5.2 Connection on the splitter DT50

The display DM60 connects to Climatic™ on the screw terminals of the card DT50.

5.2.1

The board is equipped with three RJ12 phone jacks and a screw connector (SC).

Jumpers:
The "displays" are directly supplied by the Climatic™ board with a 30 VDC power supply. Pay attention to the value of
this voltage when multiple cards are used.
J14 and J15 closed or cut the power supply:

J14 and J15 set between 1-2:
Connectors A, B, C and SC are in parallel. Power is available on all connectors.

J14 and J15 set between 2-3:
B and C connectors are supplied in parallel but the connectors A and SC are not.
Displays connected to these ports are not powered.

If J14 and J15 are set differently, the dispatcher DT50 DOESN'T WORK and therefore displays connected don't work

Each Climatic™ must be set with a communication address different.
The address setting must be done with a DS60 in (3171).
The value of the addresses must be between 1 and 8

Each Climatic™ must be set with the same number of identification Master (ID).
The ID must be equal to the communication address of the card where the DC60 is connected.
The ID setting must be done with a DS60 in (3173).

Each Climatic™ must be set with the same sub-bus identification.
The sub-bus setting must be done with a DS60 in (3172).

For each Climatic, with a DS60, you must set in (3151) the type of remote display, DC or DM.
