Star-up, adjustments, use and commissioning | 31
H.4.9 Space pressure sensor
Whenroom/spacepressurecontrolisrequested,adifferentialpressuresensorwillbeshippedforinstallationintheeld.Thepressure
sensor will be required to be installed according to the manufacturer’s instruction.
H.4.10 Damper actuators
The units will be provided with a modulating damper motor with spring return function. They are powered by a 24 VAC signal and are
controlled by a 2-10 VDC signal.
H.4.11 Room/Space temperature sensors
Room/Space temperature sensor are also available for units that require space temperature maintenance/conditioning rather than
discharge/supply air temperature maintenance.
H.4.12 Frost protection
For the frost protection of the heating coil, the entering air temperature on the coil will be monitored. If the coil’s averaging bulb
temperature drops below threshold, the fans stop, dampers close and energy recovery wheel, if available, will be turned off.
H.4.13 Economizer mode
An outdoor temperature sensor has been installed inside the unit. The outdoor temperature is used to determine if economizer
functionality is available.
H.4.14 Energy recovery wheel (ERW)
The ERW capacity is controlled by modulating the speed of the rotor. This is controlled by a frequency converter that requires a 24 VAC
enable signal and a 0-10VDC analog speed control signal.
