SERVICE MANUAL – HEAT PUMP
Set.compens.HP : selecting the option allows the
heating curve to be started in CH mode.
HP set compens. : four points are set, where X cor-
responds to the ambient temperature and Y to the
water temperature setpoint. The remaining points
are calculated by interpolation. The Y value does not
change below the first point and above the last point.
The Y4 value is equal to the SetPoint set in the main
screen.
User Pump 1 defrost req : preset constant flow rate
during defrost expressed in percentage.
User circuit mode : selection of use of Y1 and Y3
outputs
• 3WV2+3WV3 – two outputs for three-way
mixer valves controlled by 0-10V signal
• Pmp2+3WV2 – Y1 output controlled by 0-10V
signal, supporting mixer valve; Y3 output con-
trolled by PWM signal, supporting circulating
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 second
heating circuit
Set point : Set temperature value of the second
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 second 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.
