Page 3: General Description
GENERAL DESCRIPTION This equipment is an electronic device that controls packaged water cooling systems via air and reversible air/water heat pumps: (EAC/EAR 0251SM to 1804SM). The thermostat allows the following operations: - Unit ON/OFF. - Select system operating mode. - Set point adjustment. - Alarm signal relay. - Page 4 THE KEYPAD INCORPORATED AT THE UNIT, MODEL Climatic ® This is a 3-digit display, the inlet water temperature is shown in degrees (default), ºC (when shows decimal point). The following can also be displayed: - Values of all parameters controlled by the equipment. - Cooling set point, cooling differential temperature.

On heat pump units, it is possible to select cooling or heating mode with a remote contact. The ON/OFF remote can be combined with this function in order to control the unit from a long distance, with the Off/Cool/Heat options.

- Page 20 DESCRIPTION OF THE DEFROSTING SYSTEM The defrosting process is activated during heating mode in heat pump units, when the outside temperature is low and the outdoor coil could become frozen. To melt the ice the defrosting function will switch the unit to cooling operation for a short period. During defrosting mode the low pressure is at minimum level, consequently the pressure switch is disabled in this mode.

Page 21: Fan Speed Control
FAN SPEED CONTROL (only for 0091 to 0812 units) It is managed by a fan speed control printed plate located at the electrical box of the unit. The function of the fan speed control is to prevent very low condensing temperatures during cooling mode operation between 0ºC and 46ºC outside temperatures. - Page 22 SAFETY DEVICES The units contain various safety devices to avoid damage to the unit due to very low water temperatures. This protection is activated by the control of the unit when the outlet water temperature probe (St2), located inside the water exchanger, measures +5ºC and deactivates when the outlet water temperature probe reaches to +6ºC again.
