CHAPTER 3 - USER’S GUIDE
Here is a typical application (figure 4). In this example, an
ECS-4M and an ECS-5M in cascade are illustrated to
demonstrate the complete operation of the DIP-1/115.
Here is a description of this installation:
WINTER POS, SUMMER POS: Functions 1 & 2 allow
setting of a minimum opening position (in percentage) for
each season.
TEMP.: Functions 1 & 2 secondary mode allow setting of
temperature for winter and summer. When outside
temperature is between 0ºC(20°F) and 20ºC (70°F) and
none of the ventilation stages are activated, the air inlet
varies between the minimum winter position and the
minimum summer position.
When temperature reaches 20°C (70°F) (stage 1). The
ECS-5M’s first fan begins to operate, the air inlet opens at
23% and varies to 30% as the fan’s speed increases. (In
fig. 4, the ECS-5M’s first fan is in continual ventilation, “- - -”
is displayed at position 3 and the air inlet varies between
the minimum position (summer, winter), and the end
position for the first stage).
When the temperature reaches 22ºC (74°F) (stage 2).
The ECS-5M’s second fan begins to operate, the air inlet
opens at 37% and varies to 44% at the same time as the
fan’s speed accelerates.
When the temperature reaches 25ºC (78°F) (stage 3).
The ECS-4M’s first fan begins to operate, the air inlet
opens at 51% and varies to 58% at the same time as the
fan’s speed accelerates.
When the temperature reaches 27ºC (82°F) (stage 4).
The ECS-4M’s second fan begins to operate, the air inlet
opens at 65% and varies to 72% at the same time as the
fan’s speed accelerates.
When the temperature reaches 28ºC (84°F)(stage 5).
The ECS-5M’s third fan begins to operate, the air inlet
opens at 79%.
