Display
GV-HR 130 is supplied with an enclosed display (AA4)
which is also a room sensor.
Install the display in a neutral position where the set
temperature is required. A suitable location might be on
a free inner wall in a hall approx. 1.5 m above the floor.
It is important that the display is not obstructed from
measuring the correct room temperature, for example
by being located in a recess, between shelves, behind
a curtain, above or close to a heat source, in a draught
from an external door or in direct sunlight. Closed radi-
ator thermostats can also cause problems. The display
contains a light sensor that regulates the brightness; for
this reason, it should not be placed close to a lamp.
