Control Features:

Standard:

Variable adjustment – trickle and boost speeds set at installation for both motors independently
Designed for use with 125mm Round Plastic Ducting
Boost setting – with integral overrun timer adjustable up to 20 minutes
Optional delay-on-timer – boost speed does not operate if switched off within 2 minutes (adjustable from 0-20 mins)
Integral frost-stat – proportionally reduces intake motor speed as temperature falls
Water level sensor – shows if condensate exit is blocked and stops the unit

Factory Set Options

Change of ductwork handing
Purge boost – for rapid air change
BMS connections – for remote motor shut off
Integral humidistat – proportionally increases motor speeds with rising humidity
Summer bypass – automatic bypass of Heat Exchanger

Typical Consultants Specification:

Supply and install a Vectaire WHHR Mini DC energy efficient MVHR as manufactured by Vectaire Ltd, Lincoln Road, Cressex Business Park, High Wycombe, Bucks, HP12 3RH. The unit is to give a low level, continuous ventilation to a kitchen and one other wet room. The unit should be for loft or void installation and recover up to 83% of heat from extracted air separating the airflows using a counter flow heat exchanger. The unit should incorporate a low energy EC motor with sealed for life bearings for low noise levels and low energy consumption, and have as standard: variable adjustment; boost setting with integral overrun timer; optional delay-on timer; integral frost-stat; and a water level sensor. It should also have the facility for change of ductwork handing; purge boost; BMS connections; integral proportional dynamic humidistat; and an automatic summer bypass. The unit should be capable of being fitted to 125mm dia ducting without the need for adaptors, have EPS lining for low noise levels and low heat loss. The unit should comply with Part L1 2013 and Part F 2013 of Building Regulations, be EU RoHS Directive Compliant, conform to the requirements of EC Council directives relating to Electromagnetic Compatibility and Electrical Safety: 2006/95/CE (LVD), 2004/108/CE (EMC), EN 60335-2-80, be CE marked and SAP Q Eligible
