P 59
Warm water pump man/auto
Setting of type of pump control; Man –pump manual run, Auto – pump automatic run according to the
current requirements.
Value 0 – Man
Value 1 – Auto
Attention! The value 0 is only designed for HW pump service testing.
The permanent setting of pump manual run can result in water heater chilling. Therefore keep the set
value1.
P 60
Warm water pump off/on
Warm water pump switched on in case we have selected value 0 – Man on the line no. 59.
Value 0 – Switched off
Value 1 – Switched on
Note: In case the value 0 is selected in P 59 parameter it is necessary to select here the value 1. If it
be to the contrary the pump will not be active.
P 61
Warm water pump slowing-down
[min.]
We select warm water pump slowing-down on this line
P 62
Day of warm water pump spinning
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 – TV pump spinning is not active
Value 8 – TV pump spinning is active every day
Note: If at this time the pump is working the function is not active
P 65
Three-way HW valve man/auto
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.
P 66
Current status of HW three-way valve
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.
P 67
HW three-way valve slowing-down
[min.]
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.
P 70
Outside temperature reset
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
P 71
Space hysteresis
[
o
C]
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.
P 72
Space effect
[%]
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.
P 76
Minimum heating circuit temperature
[
o
C]
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.
