  • Page 3: Control Description

    CONTROL DESCRIPTION 1.- CLIMATIC 40 CONTROL 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.
  • Page 4 CONTROL DESCRIPTION CLIMATIC 40 CONTROL The figure and the table below, show the symbols present on the display and on the keypad and their meanings: Main screeen shows: inlet water temperature for ECOLEAN, ambient temperature for AIRCOOLAIR and unit status (On/Off) for AIRCUBE.

  • Page 5: Dc4 Terminal (Ecolean)

    Set point has no meaning in Aircube units because the compressors are directly controlled by remote contacts. 2.- DC41 REMOTE CONTROL (ECOLEAN) 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.

  • Page 12: Advanced Functions

    ADVANCED FUNCTIONS 1.- REMOTE ON/OFF This function allows you to turn on/turn off the unit by a simply remote contact (contacts 95-96). Close contact = ON; Open contact = OFF. 2.- REMOTE CHANGEOVER WINTER/SUMMER On heat pump units (also in Aircoolair cooling only + electrical heater), it is possible to select cooling or heating mode by a remote contact (contacts 97-98).

  • Page 13: Bms Comunications 2

    ADVANCED FUNCTIONS 4.- BMS COMMUNICATIONS Since the unstoppable growing trend of Building Automation, driven by the powerful ever evolving connectivity, controller climatic 40 offers the possibility to communicate to Building Management Systems (BMS) via Modbus protocol. Modbus standard interface is integrated in the control, so you don’t need any sort of gateway, router, etc.

    ADVANCED FUNCTIONS WATER PUMP- WATER FLOW SWITCH (ECOLEAN) Water flow switch assures that water pump does not work when there is no water flow. There is a by-pass during the first 150 seconds of water pump operation because of water flow switch signal. When the alarm has been activated, water pump is stopped. Water pump starts again every 90 seconds during a time of 50 seconds, to try to reset the alarm.

    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 between 0ºC and 46ºC outside temperatures. Depending on the unit, this function could be: ..- PROPORTIONAL CONTROL BASED ON PRESSURE Models: ECOLEAN: EAC + kit -15ºC and EAR 251-812 SM AIRCOOLAIR:...

  • Page 18: Free Cooling 7

    ADVANCED FUNCTIONS 11.- FREE COOLING This option takes advantage of external conditions for cooling mode. The freecooling is enabled when outdoor temperature is 1ºC lower than indoor temperature and when the first one is: - < 10ºC, deactivate compressors and open completely air intake gate in order to refresh only by outdoor air (enough in this conditions). - >10ºC, open air intake gate and delay compressors, which turn on only in the case outdoor fresh air would not be sufficient to achieve comfort setpoint.

    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 exchan- ger, measures +4.5ºC and deactivates when the outlet water temperature probe reaches +5.5ºC again. When the protection is activated occurs as follow: - If the unit operating mode is STAND-BY : the water pump goes on, the same happens to electrical heater of water exchanger and electrical heater of water tank (if included).
