1. Temperature.
Temperature
The outdoor temperature is measured on incoming air close to the AHU. The temperature can differ a little from
the real outdoor temperature, depending on the duct length, insulation etc.
The supply air temperature is measured in the supply air duct, normally about one meter from the AHU. Supply air
is the fresh air that - after possible heating - is sent into the room.
The exhaust air temperature is measured close to the AHU. Exhaust air is the air that leaves the room and goes
back to the AHU, where the heat is recovered.
The extract air temperature is measured close to the AHU. Extract air leaves the AHU and is sent out from the
house.
The room temperature is measured with an external sensor, placed in an appropriate place in the flat/house.
The freeze protection temperature is only used with water heating and shows the temperature of the return water
from the heater. To prevent freezing of the water heater, the AHU will stop if the water temperature is too low.
ECO adjust.
ECO adjust. is only used with exhaust air control and room control, and gives a temperature range where heating
and cooling is disabled.
Example: ECO-adjust 2 degrees and a set temp at 20 degrees means heating and cooling will be disabled
between 18 and 22 degrees. ECO-adjust is activated when ECO is enabled.
Control function
What is shown in the temperature menu depends on the selected control function. There are four control functions
to choose between, depending on application: a) supply air control, b)
cascade exhaust air control, c) cascade
room control and d) outdoor compensated supply air control.
For temperature settings and reading, choose the column that corresponds to your configuration.
a) Supply air control b) Exhaust air control c) Room control d) Outdoor compensated supply air
control
* The menu Freeze P temp. is only shown if water heater is configured.
