DESCRIPTION AND FUNCTION
INTENDED USE
The circulation pumps in this series are designed for warm
water heating systems and similar systems with constan-
tly changing
fl ow volumes. Approved fl uids are heating
water in accordance with VDI 2035, water/glycol mixture
at a mixing ratio of 1:1. If glycol is added, the delivery data
of the pump must be corrected according to the higher
viscosity, depending on the mixing ratio percentage.
Intended use of the pump/installation also includes fol-
lowing these instructions.
Any other use is not regarded as intended use.
PRODUCT DESCRIPTION
The pump (Fig. 1/1) consists of a hydraulic system, a
glandless pump motor with a permanent magnet rotor,
and an electronic control module with an integrated fre-
quency converter.
The control module has an operating knob together with
an LED display (Fig. 1/2) for setting all parameters and for
displaying the current power consumption in W.
FUNCTIONS
All functions can be set, activated or deactivated using the
operating knob.
