Description
With this setting is activated function for protection aga-
inst legionella water contamination. This function is
activated only if water warming with solar collectors, in a
time period, didn't exceed 66°C.
If this function is enabled, each switch-on according to the
time program also activates function for one-time domes-
tic hot water warming.
Select how auxiliary heat source will be activated.
Setting of delayed switch-on for auxiliary heat source.
This setting is active only if parameter "Activation strategy
for aux. heat source" P3.3= 2.
With this setting we set the operation mode and priority in
systems with more than one storage tank.
1 - OPTIMAL mode - optimal use of solar energy for
DHW warming with respect to storage tank priorities
2 - AUTO mode - automatic shift between Summer,
Optimal and Winter mode according to the calendar
3 - SUMMER mode - only priority storage tank is loaded
until it reaches set-point temperature. Other storage tanks
are loaded only when the priority storage tank has reac-
hed its set-point temperature. This operation mode is
suitable for summer period when there is no need for
room heating
4 - WINTER mode - parallel alternating loading of all
storage tanks. This mode is advisable in winter time,
when we wish to use all available energy for DHW
warming and room heating.
