Procedure to set the operating range of the modulating pump by
the heating specialist
If the design data of the heating plant deviate significantly (i.e.
differences in the design temperature of 10 K) from the standard
temperature settings of the pump, a correction should be carried
out in the following sequence:
Standard outside temp
(886)
1. Set standard outside temperature, prog. no. 886, according to
the design point of the heating plant (factory setting: - 20°C).
Flow temp setp
standard OT
(887)
2. Set flow temperature setpoint standard outside, prog. no. 887,
according to flow temperature (factory setting: 75°C).
dT differential
standard OT
(894)
3. Set dT-differential standard outside temperature, prog. no.
894, according to heating system design (factory setting:
20°C).
4. Adjusting of PWM pump in the design point with thermostat
valves open by modifying prog. no. 884 (NqmodNenn).
Function control:
Radiators do not get
warm?
If this problem exists over the whole outside temperature range,
the speed step in the design point is possibly too low; i.e. prog. no.
884 (NqmodNenn) must be increased accordingly
If this problem appears at higher outside temperatures, the speed
for heating operation has been set too low, i.e. prog. no. 885 (Nq-
modmin)must be increased accordingly.
The effects of setting modifications have to be controlled.
Mixing valve boost
(1130)
Increasing the flow temperature achieves a constant mixer flow
temperature.
Increasing: Mixer flow temperature undershoot is avoided
Lowering: Mixer flow temperature undershoot possible
DHW
Nominal setpoin
(1610)
Setting the DHW nominal setpoint
Reduced setpoint
(1612)
The DHW reduced setpoint is set under prog. no. 1612.
Release
(1620)
24h/day: The DHW temperature will be continuously controlled to
the nominal setpoint independent from the time switching pro-
grammes.
Time programs HCs: The DHW temperature will be switched over
between the nominal setpoint and the reduced setpoint depending
