t1
RETURN TEMPERATURE
The temperature of the air entering the air
conditioning unit. This temperature is
measured by the Humitemp sensor installed
inside the unit in the return air flow path.
This temperature is used by Microface,
together with “Room Temperature Setpoint”,
“Temp. Proportional Band” and “Temp.
Integration Factor” to decide the cooling or
heating status of the unit.

RETURN HUMIDITY
The humidity of the air entering the air
conditioning unit. This humidity is measured
by the Humitemp sensor installed inside the
unit in the return air flow path.
This humidity is used by Microface, together
with “Room humidity Setpoint”, “Hum.
Proportional Band” and “Hum. Integration
Factor” to decide the humidification or
dehumidification status of the unit.

TEMPERATURE SETPOINT
The temperature of the air desired in the
room. It is the reference value used by
Microface, together with return air
temperature, Temp. Proportional Band and
Temp. Integration Factor to decide the
cooling or heating status.

HUMIDITY SETPOINT
The humidity of the air desired in the room. It
is the reference value used by Microface,
together with return air humidity, Hum.
Proportional Band and Hum. Integration
Factor to decide the humidification or
dehumidification status of the unit.

FSS
FANSPEED STANDARD
The parameter used by Microface to regulate
the speed of the fan during normal operation
when an Analogue Output of Microface is
used to drive the fan.
The corresponding Analogue Output must be
assigned to Fanspeed.
NO
FSd
FANSPEED DEHUM
The parameter used by Microface to regulate
the speed of the fan during Dehum operation
when an Analogue Output of Microface is
used to drive the fan.
The corresponding Analogue Output must be
assigned to Fanspeed.
