6.1.4

Electronic control

Substations with electronic control must be set in accordance with
manufacturer´s instructions.
Where the room temperature is controlled by radiator thermostats,
it is recommended that thermostats be set for minimum
temperature in each room.

6.1.5

Outside temperature sensor

Outdoor sensors should be mounted so as to avoid exposure to
direct sunlight. They should not be placed close to doors, windows
or ventilation outlets.
