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

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
