8BACK-PLATE THERMOSTAT
Be certain the voltage
system you plan to
connect this thermostat to,
is consistent with the
switching power
you have chosen.
The thermostat should situated in the room where the
heating/cooling is to be controlled.
The place of installation should be chosen so that the
sensors can capture the room temperature as
accurately as possible, without being affected
by direct solar radiation or other heating or cooling
source.
The mounting height should be approximate 1.5
meters above the floor. The unit can be fitted
directly on the wall.
