Commissioning the controller
WARNING
Risk to life and limb due to electric shock!
Check whether the sensors and pumps have been
connected to the controller and the controller housing
is closed.
Do not apply voltage to the controller before that.
A detailed description of the commissioning of the controller can be found in the
enclosed controller manual.
1.
Makes sure that the circulation station is integrated correctly into the potential
equalisation of the system.
2.
Slowly open the piston valves on the secondary side (B) and (N).
3.
Connect the circulation station to the power supply system (230 V, 50 Hz).
The circulation station is pre-set in the factory for operation in combination with
a pre-heat buffer (hydraulic version 39). The pre-setting must be adapted
according to the system depending on the application.
4.
Carefully open and close the venting device on the check valve (A).
5.
Select the manual mode for the secondary pump in the selection menu of the
controller (see controller manual).
Switch on the PWM signal of the secondary pump ("100 %").
6.
Allow the secondary pump to run for 3 minutes.
7.
During this time, vent the circulation station several times on the vent plug of
the check valve (A).
8.
When you no longer hear any air noises, switch off the secondary pump.
7.3
Venting the circulation station
1.
Allow the primary and secondary pumps to run for several minutes in manual
mode.
2.
Vent the primary side carefully via the manual air vents (O) ans (P).
3.
Vent the secondary side carefully via the vent valve on the check
valve (A).
4.
After venting, check the operating pressure of the tank and, where necessary,
increase the pressure.
5.
Set the controller to automatic mode.
6.
Check the station for leaks and set the desired temperature on the controller
(see following chapter).
7.
The circulation station is now ready for operation.
