SERVICE MANUAL
– HEAT PUMP
Manual Mode
: choice between automatic control
and manual setting of the mixer valve
Valve level/Manual set
: in the case of automatic
mode, displays the current position of the valve, in
the case of manual setting - a field for entering the
set opening value
Circ. Temp
: temperature measurement of the third
heating circuit
Set point
: set temperature value of the third heating
circuit
Kp
: regulator gain
Ti
: integration constant of the regulator
Td
: differentiation constant of the regulator
Compens.
: four points are set, where X corresponds
to the ambient temperature and Y to the setpoint
of the feed water temperature of the third heating
circuit. The remaining points are calculated by inter-
polation. The Y value does not change below the first
point and above the last point.
Regulation type
: type of control of the buffer dis-
charge pump:
•
Plant temp.:
regulation depending on the
current temperature in the buffer
•
UnitON.:
on whenever heat pump is on
•
OFF.:
always off
•
Always ON:
always on
Setpoint
: temperature setpoint in the buffer
Differential
: hysteresis
If the water temperature in the buffer exceeds the
setpoint, then the pump will start and discharge the
buffer. The process will continue until the tempera-
ture drops below the setpoint - hysteresis value.
Setpoint read
: if you set the buffer discharge tem-
perature setpoint in the Setpoint field greater than
the actual buffer temperature setpoint, the discharge
setpoint will be set to a value 1 degree Celsius less
than the buffer temperature setpoint.
Hours
: the amount of time the circulating pump has
been running since the last reset of the application
Next thr
: Time after which the component should be
replaced/maintained
Reset h.
: switch to reset the counter
Status
: current control value set for the circulating
pump expressed as a percentage
Manual
: option to manually task the circulation pump
with a fixed flow value expressed in percentage
