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
