Helix™ Microprocessor Controller
As standard, the Helix™ microprocessor controller can provide 2, 3 or 4 stages of capacity control, dependent upon
model type.
Optionally, the controller is designed to provide capabilities for:
● Building Management Systems.
●
Networking.
● Sequencing (Master/Slave and Run/Standby) to meet all your system requirements, please confirm at time of
order. Please contact Airedale for further details.
Optimised Head Pressure Control
The fan’s speed is modulated to maintain an optimised condensing pressure, ensuring the unit is always operating in the
most efficient way and down to temperatures as low as -20°C. Head pressure can be monitored and values viewed at
the microprocessor display.
Remote Setpoint Adjust
Allows the chilled water setpoint to be adjusted via an external 0-10V signal.
Sequence Controller
For the efficient temperature and capacity operation of multiple units on a single site, the sequence controller will permit
interlinked operation of the complete system thereby providing optimum temperature control and minimum power
consumption. Included within this package is a site visit by Airedale Controls Specialists to set up multiple unit sequence
control.
BMS Interface Card
BMS cards provide an interface between the Airedale unit and the majority of BMS systems, they can be selected and
factory fitted as a standard option (please contact Airedale). A wide range of protocols can be accommodated which
include the following standard protocols; ModBus; Carel; SNMP; LonWorks; Metasys and BACnet.
Alternatively Airedale’s Ethernet TCP/IP based plug-in card, the pCOWEB, offers BACnet IP, Modbus IP and SNMP
features.
