CONNECTING THE UNIT TO AN EXTRACT & OR SUPPLY FAN
SYSTEM (Single phase supply & running current no greater than
8amps)
Where an extract fan or additional supply fan is required in the system, the
on/off control of this device can be enabled via the Innovair units. This is
achieved using the extract fan relay controlled via the IQeco. The relay will
stay energised for as long as the damper is cycling – note that it won’t just
energise when the damper is open. The relay is provided mounted and wired
inside of the Innovair control panel for connection on site using 3 core mains
cable size 1.0mm
2
cable.
Important:
The maximum electrical ratings for the external device (i.e. Extract Fan) are
as follows:
8A
250V AC1
3A
250V AC11
8A
24V DC1
INTEGRAL CO
2
SENSOR
The Biddle supplied CO
2
sensor comes fitted to the front of the unit behind the
recirculation inlet. For installations where the unit is to be exposed to the room
air, this is sufficient. However for installations where the unit isn’t directly
exposed (such as a recessed unit above a suspended ceiling) the sensor is
supplied on a 3m flexible lead to allow for remote positioning in the space’s
air.
THE CO
2
SENSOR CONNECTIONS ARE VOLTAGE FREE AND SHOULD NOT BE
CONNECTED TO ANY OTHER VOLTAGE SOURCE.
