NOTE:
• Following a ELECTA shutdown due to the opening of the "Remote On/
Off" outer contact or a power outage, the operating status previously
stored in
USER INTERFACE
will be reset at the next start-up
• The OFF command to the heat pump involves the complete deactivation
of all aspects of production of cold water, hot water and hot water.
• Compressor start-up consent is obtained only if the water circulator
(Pump 1) is active therefore, in the event of water production request for
heating or cooling of rooms not controlled by KCTR (accessory provided
separately), the relative room thermostat must be connected to "Pump
1" contact (clamps L - K of SC) to activate Pump 1

can be automatically set, through the On/Off timer available in the
