Timer mode
This mode allows for water heating during specific periods of the day or night and allows with
menu buttons to select water heating by heat pump in sub-mode
“HP”
; by heat pump and
electric heater in sub-mode
“HP+EL”
; by the solar collector in sub-mode
“Solar”
; by the
electric heater and the solar collector in sub-mode
“EL+Solar”
when the solar collector is
heating all the time while additional heating is procured by the electric heater if the
environmental conditions are not favorable; by heat pump and solar collector in sub-mode
“HP+Solar”
when the solar collector is heating all the time while additional heating is procured
by the heat pump if the environmental conditions are not favorable; or by electric heater alone in
sub-mode
“EL”
. The beginning, and correspondingly end of operation period, is indicated in
the display right side. Initial time is displayed when the operation has still not begun, while after
beginning is displayed the end time.
Boost mode
This mode is for rapid water heat and combines heating with the heat pump and electric
heater in full power in order to reach quickly desired hot water temperature. The maximum
water heating temperature in this case is 55°
С
, combined operation ending at 45°
С
and then
additional heating only by the heat pump.
Holiday mode
Often, due to various reasons (vacation, travel, etc.), a building or a dwelling, where a solar
system is installed is left for a period of time. In such cases the fact of non-using hot water from
the water heating tank may cause the accumulation of so much solar energy as to overheat.
The Holiday Mode is designed for just such circumstances. The way it works is as follows:
During the hours set out for Holiday Mode, the system will be inoperative. However overheat
protection mode will work as usual, i.e. when the collector temperature reaches the temperature
28
