correspon ing value on the gra uate scale.
PROBLEM SOLVING
PROBLEM POSSIBLE CAUSE SOLUTION
The system oes not start Wrong wiring Check if the wiring connections
to the thermostat terminals were
carrie out as per wiring iagram
The set room temperature has
been alrea y reache
Increase or re uce the set
temperature value accor ing to
the system application
(heating/air-con itioning system)
Switch on OFF position Put switch onto ON position
The ambient temperature oes
not correspon to the
temperature set on the
thermostat
Incorrect positioning of the
thermostat within the room
Follow the instructions of
paragraph “Placement of the
thermostat”
Air raughts coming from the
electrical wires con uit
Seal the con uit to prevent
warm or col air raughts
