Dry operation (damage to pump)

NOTICE!

Damage to the pump due to dry operation!

The controller is a component of the heat interface

unit. The controller and the heat interface unit draw

energy from the same connector. If the controller is

connected to the mains power before filling the heat

interface unit, then the pumps operate dry and will

be damaged.

– Fill the heat interface unit before connecting the

controller to the mains power.

The controller is prewired and ready-to-plug. The

operating company only needs to produce the fol-

lowing connections:

– Input HTG demand

– Remote off (optional)

– Power cable
