Electric back up management – Booster mode
By pressing operation button until the blue led is blinking, end users can activate the booster mode. In this case the
software will manage the electric heaters under certain conditions.
If after 120’ from the start up of the system (time counter does not start when the automatic mode is set but when the
heat pump is switched on), water set point is not reached, the first electrical element will be activated automatically.
The other steps, one by one, will be turned on every 120’ following water temperature trend, up to reach set point.
To exit the booster mode, it’s necessary to repeat the starting procedure.
Electric back up management – Super Booster mode
By pressing operation button until yellow led is turned on (3 beeps will be listened when the button will be released),
end user can activate the super booster mode. In this case all electric elements connected are switched on in one shot,
together with the heat pump. When water set point is reached, all heaters are switched off.
To exit super booster mode, it’s necessary to repeat the starting procedure.
This option is very useful when it’s necessary to heat the water as soon as possible.
Electric back up management – Automatic modes
Emix tank software can automatically manage electric back up heaters under certain conditions. This mean that these
operation modes are not to be set and that can not be deactivated.
They are:
- Antifreeze mode
- Cold draft prevention
- Electric water heater mode
Electric back up management – Antifreeze mode
If water temperature inside the buffer tank is lower than 10° C, all electric elements connected are switched on. When
the water temperature reaches 11° C all the elements are turned off.
Electric back up management – Cold draft prevention
If water temperature is lower than 40º C and one or more indoor units is in cold draft condition, one by one electrical
element are switched on per time (every 10’) and switched off all together when water temperature reaches 50º C and
no cold draft condition on any indoor unit is detected.
Electric back up management – Electric water heater
If the outdoor unit is stopped for maintenance of end user’s decision (no communication), Emix tank unit could be used
as controller of the electrical heater elements located inside the tank, exactly like any electric water heater. In this case,
if the water temperature is lower than the desired temperature for more than 30’, all the connected electrical heaters will
switch on up to the reaching of the setpoint. End users can switch off Emix tank if they do not want to have this option.
