ATLAS D ECO 30/42 K 100/130 UNIT
High efficiency hot water tank circulating pump
For proper operation of the boiler ATLAS D ECO 30/42 K 100/130 UNIT, the speed se-
lector (see fig. 19) must be set to position III.
High efficiency heating circulating pump
The factory setting is suitable for all installations; however a different operation strategy
can be set, depending on the characteristics of the system.

- Proportional Head Dp-v setting (fig. 20)
The circulating pump head will be automatically reduced with the decrease in flow rate
required by the system. This setting is optimum for systems with radiators (2 pipes or sin-
gle pipe) and/or thermostatic valves.
The strong points are the reduction in power consumption with the decrease in system
demand and reduction of noise in radiators and/or thermostatic valves. The operating
range is from min. (1) to max. (7).
- Setting Fixed speed (fig. 21)
The circulating pump does not modulate its power. The operating principle is that of con-
ventional 3-speed circulating pumps (with a reduction in power consumption compared
to them). The operating range goes from speed 1 (I) to speed 3 (III).

For a correct result of the "Thermal quantity balance" calculation (see section 11 THER-
MAL QUANTITY BALANCE (METERING), the circulating pump must be set to "Con-
stant speed " and to the position
several times until the LEDs shown in the figure below light up.
However, a different operating strategy can be set, depending on the characteristics of
the system.
- Setting p-v Proportional Head
The circulating pump head will be automatically reduced with the decrease in flow rate
required by the system.
The strengths are reduced power consumption as the system demand decreases, and
reduced noise. The operating range is from minimum to maximum.
- Setting p-c Constant Head
The circulating pump head is constant as the flow rate required by the system varies.
- Setting Fixed speed
The circulating pump does not modulate its power. The operating principle is that of con-
ventional 3-speed circulating pumps (with a reduction in power consumption compared
to them). The operating range is from speed 1 (
