    Epsilon Echos + TECHNICAL FEATURES ELECTRIC CONTROL BOARD With general isolating device, protection of the power and auxiliary circuits. Microprocessor management of the unit with main functions shown on display. STRUCTURE The electric control board is made up from: In galvanized sheet steel and painted with polyester powders RAL 7035 at 180 °C, which confer high resistance to at- • Main isolating switch and automatic circuit breakers protec- mospheric agents.
  • Page 6 Epsilon Echos + VERSIONS • Remote ON/OFF from digital input • 0-10V or 4-20mA for external management of compressor /LN: Low noise unit modulation (only for /LE and /LE/HP versions) As well as the components of the basic version, the unit • Condensate drain pan(standard for model 9 and 15) has a completely sound insulated compressors compartment.
  • Page 7 Epsilon Echos + DESCRIPTION FOR FUNCTIONS AND AC- The control device monitors the outlet probe of the exchanger (even when the unit is in standby) and when this registers CESSORIES a water temperature of 5°C or less (or 2°C below the set point temperature, with a differential of 1°C) it triggers the antifreeze heater.
  • Page 8 Epsilon Echos + Unit shutdown due to temperatures lower than the functioning limit This accessory is available for the /HP and LE/HP units. It stops the compressors of the unit when this is in heat pump mode and the external air temperature falls below a minimum set temperature: the controller stops the compressors before the unit triggers the low pressure alarm, avoiding the need to ma- nually restart the machine.
