Step 3: Installing the energy-saving controller
The actuator can be installed on all standard heating valves. There is no need to drain away water
or fiddle around with the heating system before doing this. First, you need to remove the old
thermostat dial:
•
Turn the thermostat dial anticlockwiseas far as it will
go (A).
•
Release the thermal ring of thethermostat (B).
•
Remove the thermostat from the valve (C).
An adapter will need to be used in the case of certain valves. Adapters for Danfoss valves (RA,
RAV, RAVL) are included in the scope of delivery. For details, please refer to the adapter
overview (see 18).
•
The adapter must be placed on the valve and turned
until it is securely seated.
•
In the case of the RAV adapter, the extension
supplied must be attached to the valve tappet.
•
The RA and RAV adapters must, in addition, be
secured by means of the bolt and nut supplied.
The energy-saving controller can only be installed if “INS” is showing on the display. Following
installation, the actuator will perform an adjustment run so that it can adapt to the valve. During
this process, “ADA” will be displayed.
•
Place the actuator on the valve.
•
Tighten the union nut.
•
“INS” will appear on the display, press the OK button.
•
The actuator will perform an adjustment run (“ADA” will appear on the display,
operation not possible).
•
After that, the actuator will be ready for operation (Auto mode).
If the adjustment run was initiated prior to installation, or if an error message will be
displayed (F1, F2, F3); press OK to move the motor back to the “INS” position.
1. Setting the weekly program
The weekly program allows you to set up to 3 separate heating periods (7 switching times) for
each day of the week. Programming is performed in relation to the selected days, for which
temperatures must be stored for a period from 00:00 to 23:59.
Press and hold down the menu button for more than 3 seconds.
•
“PRO” will appear on the display.
•
Confirm with OK.
•
“DAY” will appear on the display. The setting wheel can be used to select an individual
day of the week, all working days, the weekend or the entire week (example shows
working days selected).
