3.5 Outdoor temperature compensation
The ES10 is equipped with an outdoor temperature compensation function. The outdoor
temperature is measured with a temperature sensor fitted in clamps 3, 4. The measuring
range of the sensor is -40,0 to +60,0
C. The outdoor temperature compensation function is
activated by setting setpoint no. 6 in the setpoint menu to the value
”1”. If the outdoor
temperature falls below the outdoor temp. comp. max value (Setpoint no. 7 in the setpoint
menu is adjustable from -10
C til +15
C), the reduction of the pressure/flow setpoint will
start. This reduction will continue until the value temp comp min is reached (setpoint no. 8 in
the setpoint menu is adjustable from -25
C to 0
C). The size of the reduction is set in
setpoint no. 9 in the setpoint menu. This value is adjustable from 0Pa to 500Pa or from 0m/s
to 5.00m/s. Note that the outdoor temperature compensation only is active in day mode and
max mode, and not in night mode. See fig. 3.2.

3.6 Motor control
Connection. The ES10 has a 0-10VDC output (cl 12,13) for control of a frequency converter
or a triac controller. Furthermore the ES10 has a operation relay (cl 16,17), which will be
closed when the unit is in day, night or max mode operation. In case of an error message
from the frequency converter, the triac controller or the motor, the ES10 is equipped with an
error input on clamps 14 and 15. These clamps are to be shortened for fault free operation.
See section 3.4 for further information on alarm control. The current motor speed is
displayed in the main menu. See section 3.1.
Control signal. In setpoint menu no. 10 it is possible to set the max voltage on the 0-10VDC
output during operation. This setpoint is adjustable from 50% to 100% (50%=5,0VDC,
100%=10,0VDC). In setpoint menu no. 11 it is possible to see the min voltage on the 0-
