Electrical Connection Of Actuator; Use Of High-Efficiency Pumps - oventrop Regumat-180 Installation And Operating Instructions For The Specialised Installer

6.3 Electrical connection of actuator

For power supply, the actuator has to be connected
to a heating circuit controller.
WARNING
Danger to life due to electric shock!
When working
controller, there is a risk of a fatal
electric shock.
• Electrical connections must only
be carried out by a qualifi ed
electrician.
• The following 5 safety regulations
must be observed during installation
and cabling:
- Disconnect
- Protect against accidental restart
- Check that no voltage is present
- Earth and short-circuit
- (If necessary) Cover adjacent live
parts
Connect the three
(anticlockwise), L1 white (clockwise) and blue
(neutral) according to the wiring diagram (illustr. 23)
and the relay assignment of the controller.
The separate controller manual must also be
observed for the connection of the actuator.
6.4 Use of high-effi ciency pumps
The product groups "Regumat" are suitable for use
with standard high-effi ciency pumps.
NOTICE
A modifi cation of the thermal insulation is not
permissible! The pump motor must not be
covered. The max. fl uid temperature must be
observed!

The high-efficiency pumps are electronically
controlled and offer different settings. The pump
setting should be chosen depending on the
application. The following settings are recommended
by the pump manufacturers:
Application radiator heating (two pipe system)
- Automatic setting; alternatively
- ∆p-v Differential pressure variable
Application radiator heating (one pipe system)
- ∆p-v Differential pressure variable
Application underfl oor heating
- Automatic setting; alternatively
- ∆p-c Differential pressure constant
