For the property owner
9.5.2.7 Solar panels
dT max. solar °C 7 (3 to 30)
Here you can set the temperature difference determining
when charging of solar energy is started.
Type defined as “Coil”. When the solar panel is this many
degrees warmer than the solar coil in the EcoZenith, the
solar panels’ circulation pump (G30) starts.
Type defined as “Heat exchanger”. When the solar panel
is this many degrees warmer than the lower tank in the
EcoZenith, the solar panels’ circulation pumps (G30)
start.
Solar is always charged primarily in the lower tank. If
enough solar energy and temperature are present, they
are transferred to the upper tank via the heat distribution
pipes.
dT min. solar °C 3 (2 to 20)
When the temperature difference above falls to this set
value, the circulating pump (G30) for the solar panels
stops and the solar energy charge to the lower tank is
terminated.
Min. speed pump % 30 (30 to 100)
Here you set the minimum permissible rpm, in
percentage, for the solar panels’ circulating pump.
Max lower tank °C 85 (10...95)
The maximum permitted temperature in the lower
tank. Charging of the lower tank ceases once the set
temperature has been reached.
Max. brine °C 18 (1 to 30)
Setting for maximum permitted brine temperature. This
menu shows if the function “recharge the bore hole” has
been selected in the “Def Solar Energy” menu. Solar
charging of the bore hole ceases when this value has
been reached.
dT max. bedrock °C 60 (3 to 120)
Setting for start conditions for solar charging of bedrock.
Specifies the temperature difference (solar panels–
bedrock) at which charging begins.
dT min. bedrock °C 30 (1 to 118)
Setting for stop conditions for solar charging of bedrock.
Specifies the temperature difference (solar panels–
bedrock) at which charging stops.
Solar test tank min. 4 (1 to 20)
When recharging the bedrock, switching to tank charging
is performed once every 30 minutes to check whether
tank charging is possible (factory setting). The test is
carried out at the set time interval. If sufficient temperature
is obtained, tank charging continues; otherwise the
system switches to charging the bedrock again.
