1. Temperature.
Temperatures
Outdoor temperature
is measured on incoming air at the point where the sensor is located. The sensor is placed
in the outdoor air duct as far from the unit as possible. The temperature may differ slightly from the actual outside
temperature, which may depend on the length of the duct, insulation etc.
Supply air temperature
is measured in the supply air duct normally about one meter away from the unit. Supply air
is the fresh air that, after possible heating, is sent to the room.
Exhaust air temperature
is measured in the exhaust air duct close to the unit. Exhaust air is the air that leaves the
room and returns to the unit.
Extract air temperature
is measured in the extract air duct close to the unit. Extract air is the air that, after the heat
has been recovered, leaves the unit and is sent out of the house.
Room temperature
is measured using an external sensor located in an appropriate place in the apartment/house.
Frost protection temperature
is only used with water-based heating and shows the temperature of the return water
from the heating coil. When the water temperature is too low the unit will stop, to prevent freezing of the water
coil.
ECO adjusts
ECO adjust
is only used with exhaust air and room control and indicates a temperature range where heating and
cooling is not active. E.g. with ECO adjust 2 degrees and a set-point of 20 degrees, heating and cooling will not
be active between 18 and 22 degrees. ECO adjust is active when ECO is active.
Control mode
What is displayed under temperature depends on the type of control mode selected. There are five different
control modes to choose from depending on the application: a) supply air control, b) cascaded exhaust air control,
c) cascaded room control, d) outdoor compensated supply air control and e) zonal room control.
