Description
• 24 = return riser WE 1.
T-return 1 = return temperature from the system
(= T-MF 1-4).
The return riser pump switches on if the return temperature
falls below the set limit temperature T-MF 1 target.
(T-return 1 < T-MF 1 target).
It switches off again if the return temperature rises above
the set limit temperature by the amount of the hysteresis
MF 1 hyst
(T-return 1 > [T-MF 1 target + MF 1 hyst]).
• 25 = return riser WE 2.
T-return 2 = return temperature from the system
(= T-MF 1-4).
The return riser pump switches on if the return temperature
falls below the set limit temperature T-MF 1 target.
(T-return 2 < T-MF 1 target).
It switches off again if the return temperature rises above
the set limit temperature by the amount of the hysteresis
MF 1 hyst
(T-return 2 > [T-MF 1 target + MF 1 hyst]).
• 26 = return riser WE via the storage tank.
The return risers valve over storage tank opens if the tem-
perature storage tank bottom (T-buffer U) rises above the
return temperature of the system [sensor 01 or 01-04] by
the the amount of the hysteresis MF 1 hyst + 5K (T-buffer
U > T-MF 1 + MF 1 hyst + 5K).
It switches off again if the temperature storage tank bottom
falls below the return temperature (T-buffer U < T-MF 1 +
MF 1 hyst).
• 27 = tank charge pump 1 (pump operates if the hot water
tank can be solar charged).
The temperature of the charging medium for the tank is
always measured at the MF 4-sensor (T-MF 4). Exception:
For function 23 on MF 4, the sensor assigned to the
MF-relay tank charge pump 1 for the calculation of the
temperature of the medium for the charging of the tank
(T-solar) is used.
T-solar (T-MF 4) = temperature of the solar collector.
T-solar (T-MF 1-3) = temperature of the heat exchanger.
T-WW U [sensor 12] = temperature of the hot water tank in
the area around the infeed.
ON: T-solar > [T-WW U + MF hyst].
OFF: T-solar < [T-WW U + MF hyst Off].
The circulation pump switches on if the temperature of the
solar collector rises above the temperature of the tank in
the area around the infeed T - WW U by the amount of the
hysteresis MF Hyst (T-solar > [T-WW U + MF hyst]).
It shuts off if the temperature of the solar collector falls
below the temperature T-WW U + MF hyst Off (T-solar <
[T-WW U + MF hyst Off]).
Description
• 28 = tank charge pump 2 (pump operates if the storage
tank can be solar charged and the hot water tank cannot be
solar charged).
The F15 function must be at the position 5.
The temperature of the charging medium for the tank is
always measured at the MF 4-sensor (T-MF 4).
Exception: For function 23 on MF 4, the sensor assigned to
the MF-relay tank charge pump 2 for the calculation of the
temperature of the medium for the charging of the tank
(T-solar) is used.
T-solar (T-MF 4) = temperature of the solar collector.
T-buffer U [sensor 01] = temperature in the storage tank in
the area around the infeed.
The circulation pump switches on if the temperature of the
solar collector rises above the temperature of the tank in
the area around the infeed T-buffer U by the amount of the
hysteresis (T-solar > [T-buffer U + MF hyst]).
It shuts off if the temperature falls below the temperature
T-buffer U + MF hyst Off
(T-solar < [T-buffer U + MF hyst Off]).
• 29 = tank charge pump 3 (pump operates if tank 3 can be
solar charged and the storage tank cannot be solar charged).
The F15 function must be at the position 5.
The temperature of the charging medium for the tank is
always measured at the MF 4-sensor (T-MF 4).
Exception: For function 23 on MF 4, the sensor assigned to
the MF-relay tank charge pump 3 for the calculation of the
temperature of the medium for the charging of the tank
(T-solar) is used.
T-solar (T-MF 4) = temperature of the solar collector.
T-tank 3 [sensor 159 = temperature of tank 3 in the area
around the infeed.
The circulation pump switches on if the temperature of the
solar collector rises above the temperature of the tank in
the area around the infeed T-tank 3 by the amount of the
hysteresis MF hyst (T-solar > [T-tank 3 + MF hyst]).
It shuts off if the temperature falls below the temperature
T-tank 3 + MF hyst Off
(T-solar < [T-tank 3 + MF hyst Off]).
• 30 = Reloading pump WW-tank 2.
The F15 function must be at the position 4.
The relay switches if the temperature of the hot water tank
rises above the temperature sensor 15 by the amount of the
hysteresis MF hyst.
It shuts off if the temperature of the tank falls below the
temperature [sensor 15 + MF hyst Off].
