45
Day of warm water pump spinning
P 62
On the determined day the pump spinning will be done at 12:00 h for 30 sec.
Value 1 - 7 – corresponds to days from Monday to Sunday
Value 0 –primary pump spinning is not active
Value 8 – primary pump spinning is active every day
Note: If at this time the pump is working the function is not active
Three-way HW valve man/auto
P 65
Setting of type of HW three-way valve control:
Man –valve into HW circuit permanently open
Auto – automatic three-way valve reversing according to requirement.
Value 0 – Man
Value 1 – Auto
ATTENTION!
Value 0 is only designed for valve functionality service testing.
Current status of HW three-way valve
P 66
Display of current status of HW three-way valve
In case the value 0 is selected in P 65 parameter we activate the three-way valve
in this P 66 parameter by selecting the value 1.
HW three-way valve slowing-down
[min.]
P 67
Over this set period HW three-way valve is kept open into HW circuit when the
desired HW temperature has been reached.
If the boiler temperature after the HW preparation completion is higher than HW
desired temperature plus 5
o
C the boiler slowing-down into HW circuit is active
and is followed by HW three-way valve slowing-down. If after the HW preparation
completion the boiler temperature is not higher than HW desired temperature HW
plus 5
o
C the slowing-down into from boiler is not active, but HW three-way valve
slowing-down starts immediately.
Outside temperature reset
P 70
By this parameter activation we will set the outside temperature values to zero.
Thenceforth the regulator starts to count new outside temperature values.
Value 1 – activates zeroing
Space hysteresis
[
o
C]
P 71
Setting the value of space temperature excess; only after the space desired
temperature incl. the value increase set in this parameter has been reached the
boiler operation into the heating circuit will be shut down. The boiler operation into
the heating circuit will restart after the space temperature has dropped to the
space desired temperature.
Space effect
[%]
P 72
By setting this parameter we correct the equithermal control by the space effect.
The higher is the set value the more the space effect is taken into account.
Note: Setting 100 % regards the pure space control.
Note: This parameter is active in case the QAA 88 device is selected as the space
unit (line no. 28 value 2) and the outside sensor is used.
Minimum heating circuit temperature
[
o
C]
P 76
Setting the minimum desired temperature for heating circuit.
Note: The minimum boiler temperature is taken as the minimum heating circuit
temperature in case of the version without three-way mixing valve.
Maximum heating circuit temperature
[
o
C]
P 77
Setting of maximum desired temperature for heating circuit.
