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.

Outside temperature sensor

The outside temperature sensor should be mounted on a Northfacing wall. It requires a single pair of screened wires. 
The sensor can be factory mounted in the fresh air inlet. Other items are supplied loose on a project specific basis 
and data sheets are available for these items.

Mains connection

Mains connections are normally made through the bottom of the control panel. All the cables should be suitably 
arranged so as not to put excessive strain on the terminals. They should be fitted with suitable glands to prevent 
water ingress.

Reconnection of sectionalized units 

If the unit is supplied in sections, the internal control wiring will have been disconnected in the factory between 
sections using break point connectors and the cables will be marked with identifiers. Site reconnection is to be done 
by a contractor.

Wiring requirements

Running sensor wires in the same conduit or bundle with any AC power wires other than 24VAC may cause a 
malfunction. With on site fitted items, the screened wire should be covered with insulation tape at the sensor 
terminal box. Site mounted sensor cables should be Belden 8760 for 2 core devices and Belden 9402 for 4 core 
cables.

Fire signal (option)

The AHU unit maybe interfaced to a fire alarm shut down by connecting a normally closed contact to the designated 
terminals. If this is not required, the fire contacts are replaced by a link. Remote fireman's override switches can be 
connected to allow operation of the extract fan after a fire alarm has been actuated. Where a mixing box is fitted, the 
exhaust air damper will be driven to the fully open position while the mixed air and fresh air dampers are driven 
closed.
Override contacts can be connected to the designated terminals where this option has been ordered.

Filter section

Depending on the order, a common or an individual filter switch is provided to indicate when the filter section 
differential pressure is excessive. The filters may need to be changed. 

Frost protection thermostat

In the event that the coil air on temperature drops below 5°C, a thermostat is provided to switch off the supply fan on 
units with water coils. It is a hard-wired form of protection and can only be monitored by the controller. This prevents 
hot water coils from freezing and would typically operate in cold weather if the hot water coil supply has failed.

Fan section

A pressure differential switch is provided across each fan to provide a proof of airflow indication. All fan / motor are 
belt and pulley driven.

Frequency of inspections

It is recommended to inspect all end devices supplied with the unit for correct operation and calibration on an annual 
basis.

Recommended spare parts list

If required, a list of recommended components to be kept on site can be provided.
