Solid-fuel boiler, buffer, heating circuit, and additional heat requirement
|
Basic function (P0): Heating circuit pump A1 is released via boiler temperature and buffer temperature, activation of buffer loading pump A2, burner requirement based on buffer.
A1 = (T1> min1 or T2 > min2) & (heating = active)
A2 = T1 > min1 & T1 > T3 + diff1 A5 = T2 < max
Program 1: The burner requirement is based on sensor T3.
A5 = T3 < max
Program 2: Separate switch-on and switch-off thresholds for the burner requirement.
A5 on = T2 < min2 + diff2 A5 off = T2 > max
Program 3: Like program 2, but the switch-off threshold is based on T3.
A5 on = T2 < min2 + diff2 A5 off = T3 > max
All programs +4: The burner requirement is based on the rated supply temperature.
A5 = T2 < Srated + diff2 & (heating = active)
Program 5:
A5 on = T2 < Srated + diff2 & (heating = active)
A5 off = T3 > Srated + diff2
Program 6:
A5 on = T2 < Srated + diff2 & (heating = active)
A5 off = T2 > max
Program 7:
A5 on = T2 < Srated + diff2 & (heating = active)
A5 off = T3 > max
All programs +8: The burner requirement is only allowed when the solid-fuel boiler is cold.
A5 (+8) = T1 < min1 & A5
All programs +160: The heating circuit pump A1 is only released on the basis of buffer temperature T2, and not boiler temperature T1.
A1 = T2 > min2 & (heating = active)
Time programs are possible for heating circuit A1 and burner requirement A5.

Automatic boiler, water heater, heating circuit, and boiler requirement
|
Basic function (P16): Heating circuit pump is released via the minimum boiler temperature, water heater loading pump A2, boilder requirement A5. When there is no heating operation, the boiler requirement is switched off when the rated water heater temperature is reached. The water heater loading pump runs until the boiler temperature is undercut, in order to channel the boiler's residual energy into the water heater.
A1 = T1 > min1 & (heating = active)
A2 = T1 > min1 & T1 > T2 + diff1 & (T2 < max or (heating = inactive))
A5 = (T2 < max & TP(A2)) or ((T1 < min2 or T1 < Srated + diff2) & (heating = active))
All programs +1: Water heater priority
A1 (+1) = A1 only when not ((T3 < max) & TP(A2))
All programs +2: Separate sensors for the water heater requirement's switch-on and switch-off points
A2 = T1 > min1 & T1 > T3 + diff1 & (T3 < max or (heating = inactive))
A5 on = T2 < max or ((T1 < min2 or ......
A5 off = T3 > max & ((T1 > min2 or ......
All programs +4: Like program 16, but loading pump function is only based on T2
A2 = T1 > min1 & T1 > T2 + diff1 & T2 < max (regardless of the heating)
All programs +8: Like program 16, but the burner requirement is only based on the needs of the heating circuit and water heater loading, and not on a comparison with the boiler temperature.
A5 = (T2 < max & TP(A2)) or (heating = active)
Time programs are possible for heating circuit A1 and hot water requirement A2. For A2, the time program TP(A2) only affects the requirement, and not the loading pump.

Automatic boiler, (combined) buffer, heating circuit, and boiler requirement
|
Basic function (P32): The temperature of the combined storage tank is maintained by the automatic boiler.
Storage tank loading pump A2, mixer control A3+A4, boiler requirement A5. Sensor T1 is free for possible use by the speed control functions in the boiler (supply).
A1 = T3 > min2 & (heating = active) A2 = T1 > min1 & T1 > T3 + diff1
A5 = T2 < max or (T3 < Srated + diff2 & (heating = active))
Program 33: Separate switch-on and switch-off thresholds for the boiler requirement.
A5 on = T2 < min2 + diff2 A5 off = T2 > max
Program 34: Like program 33, but the switch-off threshold is based on T3.
A5 off = T3 > max
Program 35: Holding circuit with difference based on the rated supply temperature
A1 = T2 > min2 & (heating = active) A2 = T1 > min1 & T1 > T3 + diff1
A5 on = T2 < max or (T2 < Srated + diff1 & (heating = active))
A5 off = T2 > max & T3 > Srated + diff2
Program 36: Heating circuit pump and boiler requirement separate.
A1 = T2 > min2 & (heating = active) A2 = T1 > min1 & T1 > T3 + diff1
A5 = T3 < max
All programs +8: The buffer loading pump is immediately switched on in the event of a boiler requirement (intended for condensing devices with minimum circulation water volume).
A2 = A2 or A5
Time programs possible for heating circuit A1 and boiler requirement A5. With A5, the time program only affects the hot water requirement, because the heating requirement is coupled to A1.

Buffer, water heater, heating circuit, and boiler requirement
|
Basic function (P48): Activation of heating circuit pump A1, water heater loading pump A2, and boiler requirement A5.
A1 = T1 > min1 & (heating = active)
A2 = T1 > min1 & T1 > T3 + diff1 & T3 < max
A5 on = T1 < min2 A5 off = T1 > min2 + diff2
Program 49: Like program 48, but the boiler requirement switch-off threshold is based on T2.
A5 off = T2 > min2 + diff2
Program 50: Boiler requirement based on rated supply temperature and hot water
A5 = T2 < min2 or T1 < Srated + diff2 & (heating = active)
Program 51: Like program 50, but with consideration of the water heater temperature
A5 = T3 < min2 or T1 < Srated + diff2 & (heating = active)
Program 52: Separate sensors for the burner requirement's switch-on and switch-off points
A5 on = T1 < Srated + diff2 & (heating = active) A5 off = T2 > min2
Program 53: Like program 52, with consideration of the water heater temperature
A5 on = T3 < max & (T1 < min1 or T1 < T3 + diff1) or (T1 < Srated + diff2 & (heating = active))
A5 off = T2 > min2 & T3 > max
Programs 54 and 55: Like programs 52 and 53, but A2 (hot water) has priority over A1.
A1 (54,55) = A1 only when not ((T3 < max) & TP(A2))
All programs +8: Second energy source alongside the buffer with sensor T2
All conditions set for T1 also apply for T2. The higher temperature is decisive.
Time programs possible for A1, A2 and A5. In the programs 50, 51 and 53, the time program set for A5 only affects the burner requirement for domestic water heating.

Solid-fuel boiler, buffer, water heater, and heating circuit
|
Basic function (P64): Release of heating circuit pump A1 when either the boiler temperature or the buffer temperature has exceeded its assigned minimum threshold, activation of water heater loading pump A2, mixer control A3+A4, activation of buffer loading pump A5.
A1 = (T1 > min1 or T2 > min2) & (heating = active)
A2 = T2 > min2 & T2 > T3 + diff1 & T3 < max
A5 = T1 > min1 & T1 > T2 + diff2
All programs +1: For water heater loading, the boiler temperature and the buffer temperature are both taken into account.
A2 = ((T1 > min1 & T1 > T3 + diff1) or (T2 > min2 & T2 > T3 + diff1)) & T3 < max
All programs +2: Sensor T6 is not used as a room sensor, but instead as a reference sensor for buffer loading. Note: Set T6 as standard sensor (Std) (see rotary switch position Mod - Par).
A5 = T1 > min1 & T1 > T6 + diff2
All programs +4: T5 is used as a sensor at the bottom of the buffer. Weather-dependent heating control is not possible. Note: In the mixer control parameters menu 'Mr', set Fir = fixed value control, or rtr = room temperature control.
A5 = T1 > min1 & T1 > T5 + diff2
All programs +8: With the aid of this function, the voltage-free contact A5 (in the device, on the side of the sensor terminals) is exchanged with output A2.
All programs +160: The heating circuit pump A1 is only released on the basis of buffer temperature T2, and not boiler temperature T1.
A1 = T2 > min2 & (heating = active)
For programs similar to those for the above diagram, see programs 85 and 86.
Time programs possible for heating circuit A1 and water heater loading A2.
