EAC/EAR-SM ANCM/ANHM KSCM/KSHM

Climatic 40 control, is an electronic device that controls Ecolean units EAC/EAR (chiller units), Aircoolair units ANCM/ANHM (air-air

units) and Aircube units KSCM/KSHM (condensing units).

The thermostat allows the following operations:

• Unit ON/OFF.

• Select system operating mode.

• Set point adjustment.

• Alarm signal relay.

• Display temperature, units status and pending alarms.

• Time bands programming.

• BMS comunications.

• Possibility of remote ON/OFF.

sure condenser and outdoor (optional)

temperature probes.

Proportional regulation based on inlet

water temperature (cooling and heating

mode).

Defrost cycle (heat pump units), with pres-

sure tranducer.

Condensing pressure control with tempe-

rature probe or pressure transducer.

Flow switch, antifreeze, high and low pres-

CONTROL DESCRIPTION

DC41 terminal is an optional keypad that allows to manage Climatic 40 controller from a remote position. The buttons and

indications on the display faithfully reproduce the Climatic 40 user interface.

1.1.1.- TURN ON/OFF THE UNIT

In order to turn on the unit, press for 2 seconds the “ ” button, for the heat pump mode, or the “ ” button, for the cooling

mode.

The display shows unit’s operating mode together with the symbols of the working elements (compressors, water pump etc.).

In order to turn off the unit, press for 2 seconds the “ ” button (if the unit is working in heat pump mode) or the “ ” button (if the

unit is working in the cooling mode).

1.1.2.- SELECTING THE UNIT´S OPERATING MODE

If the unit is in stand-by, the operating mode is selected in the start-up (as explained above).

In the case the unit is working in cooling or heating mode, in order to change the operating mode, you have to turn off the unit

before, and only then you can turn it on in the operating mode you want.

1.1.3.- SELECTING THE WATER TEMPERATURE OF THE SYSTEM

To modify unit working set point you have to change r1 parameter (cooling set point) or r3 parameter (heating set point).

To see how to change a parameter see chapter 3 MENU (SETPOINT SETTINGS AND OPERATING HOURS DISPLAY MENU

paragraph).

1.2.1.- TURN ON/OFF THE UNIT

The unit turns on closing On/Off contact and turns off opening it (see section 1, advanced functions, for more details).

1.2.2.- SELECTING THE UNIT´S OPERATING MODE

Heating mode is selected opening remote changeover contact while cooling mode is selected closing it (see section 2, advanced

functions, for more details).

NOTE

Set point has no meaning in Aircube units because the compressors are directly controlled by remote contacts.

DIFFERENTIAL SETTINGS

Press “ ” button for 3 seconds. Sleep differential (the value you increase or decrease to comfort set-point) appears on the dis-

play.

Use “ ” buttons to set the value, then press “ ” button to accept.

Note that cooling and heating mode have different sleep differential values, so you can modify only current operating mode’s one.

To set actual time:

1. Press “ ” button for 6 seconds. “rtc” and actual time appears on the display (hours are ashing).

2. Set the hour by “ ” buttons.

ambient temperature in respect to the set-point.

3.3.- SELECTING DESIRED ROOM TEMPERATURE

If unit is working, the “ ” buttons allow to select the desired room temperature (set-point).

The button “↑” allows the increase of the current set-point by 0.5ºC.

The button “↓” allows the decrease of the current set-point by 0.5ºC.
