Factory engineered controls
Duct static pressure sensor
The duct static pressure sensor should be mounted in the supply ductwork, approximately two thirds of the distance
from the fan to the end of the longest run of ductwork. The sensor requires two pairs of screened cable to the control
panel.
One pair supplies power to the device and the other is the pressure signal from the device to the controller. FWD

Outside temperature sensor
Capacities
Cooling capacity on water (1)
The outside temperature sensor should be mounted on a Northfacing wall. It requires a single pair of screened wires.
Heating capacity on water (2)
The sensor can be factory mounted in the fresh air inlet. Other items are supplied loose on a project specific basis
