6 Initial start-up

Initial situation:

The controller and the external sensor are correctly in-

stalled and connected.

The heating unit is switched on and ready for operation.

Note!

Ensure that both rotary knobs

(outlet-/hot water cylinder temperature and

heating flow temperature ) on the boiler are at

the maximum position (all the way to the right).

This ensures optimum control system by the

VRT 430.

The VRC 430 operating concept is described in the op-

erating instructions in Chapter 4.3.
