SPEED REGULATOR – ELECTRONIC PUMPS
In order to guarantee efficient operation of the heating installation and optimum
adaptation of the pump to the load on the hydraulic installation, it is important
to select the right control range. The pump control channel is selected using a
3-stage selector switch (Fig 5b) in accordance with the installation requirements.
The pump operates within the chosen control range and adapts continuously to the
fluctuating power requirements of the installation, in particular when thermostatic
valves are used.
After switching to a different control range, it will take some time before the
heating installation control becomes stable.
6. MAINTENANCE
No routine maintenance is necessary, however, during prolonged shutdown e.g.
summer months, it is advisable to run the pump for a few minutes every few weeks.
