Settings for solar thermal heating
A solar thermal system may work with one or two hot water storage tanks. Heating the tanks
is controlled by so called
Oscillating storage tank loading
, when the Controller tries to heat up
tank No. 1 first. If this is not possible due to too small temperature difference between the
collector and tank, and at the same time the difference for tank 2 is sufficient, it will load tank
2 for the preset time. After the preset loading time the Controller stops loading tank No. 2 and
tests if the collector temperature rises. If not, it continues loading tank No. 2. If the collector
temperature rises, the Controller waits until the difference for loading tank No. 1 is met.
Solar (active/off)
........ Switching on solar zone.
sol.cons. 1,2 (active/off)
.................................... Switching on separate tanks in solar circuit.
Solar consumer 1, 2
sensor (sensor list)
... Choice of temperature sensor in a solar tank.
diff. on (°C)
................. Difference to switch on heating from solar circuit. Difference between
solar collector and temperature sensor set in parameter
sensor
.
diff. off (°C)
................. Difference to switch off heating from solar circuit.
desired t. (°C)
............. The desired temperature. Under the normal solar circuit mode, the tank
is heated up to this temperature. As soon as all switched-on tanks are
heated up to the
demand
temperature
, the Controller continues heating
up to max. temperature.
max. temp. (°C)
.......... Max. temperature. Maximum temperature the solar tank is heated to in
normal mode (the function of solar collectors cooling is turned off).
bore regen. (yes/no)
.................................... Set if this tank is used for ground-source heat pump’s deep bore
regeneration. Selecting “yes” will start a ground loop circulation pump
together with the given consumer.
Oscillating loading
t. increase (°C)
........... Temperature increase during oscillating loading. If a solar tank of a
higher priority cannot be loaded, the Controller waits for the time set in
parameter
idle
time
. If the temperature rises after this time by the value
