PUMP: INSTALLATION AND OPERATING INSTRUCTIONS
CONTROL MODES AND FUNCTIONS
Variable differential pressure Δp-v (I, II, III)
Recommended for two-pipe heating systems with radiators to reduce the flow noise at thermostatic valves.
Constant differential pressure Δp-c (I, II, III)
Recommended for underfloor heating or for large-sized pipes, applications without a variable pipe network curve (e.g.
storage charge pumps) or single-pipe heating systems with radiators.
Constant speed (I, II, III)
Recommended for systems with fixed system resistance requiring a constant volume flow.
The pump reduces the delivery head to half in the case of decreasing volume
flow in the pipe network.
Electrical energy saving by adjusting the delivery head to the volume flow
requirement and lower flow rates.
There are three pre-defined pump curves (I, II, III) to choose from.
The control keeps the set delivery head constant irrespective of the pumped
volume flow.
There are three pre-defined pump curves (I, II, III) to choose from.
The pump runs in three prescribed fixed speed stages (I,II, III).
