Powering Up the Unit
Switching On
Switch on the power at the mains supply isolator feeding the unit and the fan motors will start.
Switching Off
Turn the power off at the mains supply isolator switch.
Commissioning Overview
The instructions in this section are intended to provide configuration and operation information for setting up the
equipment.
Follow good practice when commissioning the unit. Ensure that the system is installed according to the system
designers intent incorporating any acoustic ducting, that all joints are air tight, ducting is well supported, bends
are avoided close to vents, and that the vent valves are fully open at the start of the commissioning process.
Commissioning and Control
The commissioning control enables you to adjust the fan flow rates. These are factory set to minimum and can
be adjusted by using a small flat screwdriver through the four holes as shown below.
Measure the flow from the extract and supply grilles in the usual way. Adjust the potentiometers to suit.
Apply the label supplied in the accessory pack after the flow rates have been set to ensure that the holes are
sealed and the Moisture Ingress Protection rating is maintained.

Operation
Integra Plus ECA MVHR Installation & Commissioning 15
Modes of Operation
Normal Mode
Normal Mode is the default operating mode of the unit. The unit will run continuously in Normal Mode unless a
signal input is received from the Remote boost switch, LS1 or LS2. The Normal Mode flow rate is adjustable
within the full range of the unit, but would normally be set for background ventilation.
Boost Mode
Boost Mode can be triggered when additional ventilation is needed. Boost Mode is triggered
by an input from the Remote Boost switch, LS1 or LS2. Boost Mode will timeout after 2-
hours unless cancelled. The Boost Mode flow rate is adjustable within the full range of the
unit but is normally set at a level required when cooking or showering. The LED will not
illuminate when Boost Mode is triggered.
Remote Boost switch: Press once to activate Boost mode, press once to exit Boost mode.
LS1: Boost will activate while LS1 is active
LS2: Boost will activate while LS2 is active, after a 5-minute delay
Purge Mode
Purge mode will run the unit at 100% and can only be triggered and cancelled via the
Remote Boost switch. A 5-second press and hold of the Boost Switch will trigger, or cancel
Purge Mode. Purge mode will timeout after 30 minutes. The LED will not illuminate when
Purge Mode is triggered.
Summer Mode
Summer Mode is useful when the indoor temperature is higher than desired, and the outdoor temperature is
lower than the indoor temperature. Summer mode stops the supply fan, this prevents the recovery of heat from
the extract air stream by thereby allowing the cooler outdoor air to enter the property via an open window or
trickle vent.
To activate Summer Mode press the Boost button 3 times in less than three seconds, after a
short pause the LED will illuminate green and the supply fan will stop.
To exit Summer Mode press 3 times in less than three seconds, after a short pause the
green LED will turn off and the supply fan will restart.
Summer mode must be cancelled by the user, it will not timeout.
If the LED on the Remote Boost switch flashes green, there is an error with the units Temperature sensor. The sensor is used
by the frost protection system. If the unit was in Summer mode it will return to normal operation. Please contact the Vent-Axia
Technical Support for assistance.
