The room temperatures that correspond to the
setting fi gures on the units can be seen from the
temperature scales. Indications are for guidance
only, since the room temperatures obtained are
often aff ected by such factors as the conditions of
The temperature scales are stated according to
Xp = 0° C is the room temperature at which the
valve shuts off , while Xp = 2° C shows the room
