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
Heat pump (HP) ON/OFF TIMER:
Once the heat pump has been switched on, its start-up and switch-off
can be automatically set, through the On/Off timer available in the USER
INTERFACE.
This function is enabled by setting the 100=On parameter inside the HP
label menu
weekday, in particular:
P2 label menus.
the dAYS label menu.
NOTE:
If the On/Off timer is active and the set key is pressed for a long time, the
heat pump on USER INTERFACE or KCTR switches off, in both On and Off
time bands. By then pressing the set key for a long time again, the On/Off
timer is reactivated. Therefore, in the On time band the HP switches on
and in the Off band it remains off until change over to On band.
