Whole dwelling ventilation rate = 24l/s
(the greater of Area x 0.3 or whole dwelling rate
table in building regulations).
Whole dwelling boost rate =29 l/s
(the greater of the summation of the extract
rates or the whole dwelling rate).
As per the instructions above, turn all spindles up full. Turn the Extract boost spindle
down until the extract boost rates are achieved (kitchen 13l/s, bathroom 8l/s, en-suite 8
l/s).
Lock the valves in place
.
Turn the supply trickle spindle down to achieve the rates for the supply rooms (living
11l/s, Dining 5l/s, Bedroom 8l/s).
Lock the valves in place
.
Turn the Extract trickle down until the whole dwelling rate i.e. 24l/s is achieved through
the extract valves.
Do not adjust the valves
, only adjust the control on the unit.
Turn the Supply Boost down until the whole dwelling Boost rate i.e. 29l/s is achieved
through the Supply valves.
Do not adjust the valves
, only adjust the control on the
unit.
6.3 Humidity Control
This potentiometer control is located on the front of the unit and can be adjusted by hand
and can be set between 60%-100% (Not active) relative Humidity, causing the unit to
boost when it senses the set humidity level. Adjusting the speed pot anti-clockwise will
cause the unit to become more sensitive thus boosting the system more often.
The factory setting for humidity is 70% RH
. Turning this Speed Pot clockwise increases
the humidity level at which the unit will boost.
NB.
Upon start-up/ power-on the humidity sensor will be inactive for a period of 60mins
due to calibration.
