Page 3: Description Of Controls
DESCRIPTION OF CONTROLS 1.- CLIMATIC 40 CONTROL Climatic 40 control, is an electronic device that controls Ecolean EAC/EAR units (chiller units), Aircoolair ANCM/ANHM units (air-air units) and Aircube KSCM/KSHM units (condensing units). The thermostat allows the following operations: • Unit ON/OFF. - Page 4 DESCRIPTION OF CONTROLS CLIMATIC 40 CONTROL The figure and the table below show the symbols present on the display and on the keypad,together with their meanings: The main screeen shows: inlet water temperature for ECOLEAN, ambient temperature for AIRCOOLAIR and unit status (On/Off) for AIRCUBE.

Page 5: Dc4 Terminal (Ecolean)
There are no set points to be made for Aircube units because the compressors are directly controlled by remote contacts. 2.- DC41 REMOTE CONTROL (ECOLEAN) DC41 terminal is an optional keypad that allows the Climatic 40 controller to be managed remotely. The buttons and indications on the display faithfully reproduce the Climatic 40 user interface. -

DESCRIPTION OF CONTROLS 3.- DC40 REMOTE TERMINAL (AIRCOOLAIR) The illustration and the table below show the symbols that appear on the display and on the keypad and their meanings. OFF appears in the main field of the display if the machine is off, or the set point if the machine is working. BUTTON NAME DESCRIPTION... - Page 7 DESCRIPTION OF CONTROLS 3.1.- TURN ON/OFF THE UNIT WITH REMOTE CONTROL DC40 (AIRCOOLAIR) To turn on the unit press the “ ” button. The display shows current operating mode. 3.2.- SELECTING THE UNIT´S OPERATING MODE Once the unit is turned on, you can select Cooling, Heating or Automatic mode just pressing the “Mode” button. In the automatic mode you just choose the set point and the system automatically switches from cooling to heating mode, depending on the position of the ambient temperature with respect to the set point.

Page 12: Advanced Functions
ADVANCED FUNCTIONS 1.- REMOTE ON/OFF This function allows you to turn the unit on/off by a simply remote contact (contacts 95-96 in ECOLEAN and AIRCOOLAIR units;contacts 88-89 in AIRCUBE units). Close contact = ON; Open contact = OFF. 2.- REMOTE CHANGEOVER WINTER/SUMMER On heat pump units (also in Aircoolair cooling only + electrical heater), cooling or heating mode can be selected by a remote con- tact (contacts 97-98). -

ADVANCED FUNCTIONS WATER PUMP- WATER FLOW SWITCH (ECOLEAN) The water flow switch ensures that the water pump does not work when there is no water flow. At first, there is a by-pass during the first 150 seconds of water pump operation which operates according to the water flow switch signal. When the alarm has been activated, the water pump is stopped. -

ADVANCED FUNCTIONS 10.- CONDENSER FAN SPEED CONTROL The function of the fan speed control is to prevent very low condensing temperatures during cooling mode operation at outside temperatures of between 0ºC and 46ºC. Depending on the unit, this function could be: ..- PROPORTIONAL CONTROL BASED ON PRESSURE Models: ECOLEAN: EAC + kit -15ºC and EAR 251-812 SM... -
Page 18: Free Cooling 7
ADVANCED FUNCTIONS 11.- FREE COOLING This option takes advantage of external conditions for cooling mode. Freecooling is enabled when outdoor temperature is 1ºC lower than indoor temperature; when the former is: - < 10ºC, the compressors are deactivated and the air intake gate fully opened in order to refresh with outdoor air only (sufficient under these conditions). -

SAFETY DEVICES ANTIFREEZE PROTECTION (ECOLEAN). This protection is activated by the control of the unit when the outlet water temperature probe (b2), located inside the water exchanger, measures +4.5ºC and deactivates when the outlet water temperature probe reaches +5.5ºC again. When the protection is activated, the following occurs: - If the unit is operating in STAND-BY mode: the water pump goes on, as does the electrical heater for the water exchanger and the electrical heater of the water tank (if included). -
