UNPACKING
Unpack the device and accessories carefully from the shipping container and check that
all the items listed below can be found. Notify your reseller immediately if any items are
damaged or missing.
● The PHM-V1 device
● 2-meter-long PVC hose (2 pcs)
● USB Mini B cable
● Fläkt Woods valve measurement tool
● Carry strap (attached to the device)
COMMISSIONING
The PHM-V1 works using four AAA alkaline batteries or rechargeables. The device has been
fitted with alkaline batteries from the factory, so there is no need to install batteries when
first starting to use the device.
INSTALLING BATTERIES
Open the battery compartment by pushing the locking tab to the unlocked (right) position.
Install four AAA batteries into the compartment as shown inside. Close the compartment
and lock it by pushing the locking tab to the locked (left) position.

Measure using K-value
In the K-value measurement mode, one K-value is selected for measurement. K-value can be
changed using the keyboard. (See “K-factor measurement, page 12”).
Select valve
One pre-installed ventilation valve can be selected at a time in the CHOOSE VALVE menu.
You may adjust the valve opening using the keyboard which automatically yields the correct
K-value. (See “ Measurement using chosen valve, page 12”).
Zeroing measurement
Measurement is zeroed by selecting ZERO. A bar graph on the display indicates when the
zeroing is completed. The device will automatically return to measurement mode once the
zeroing is completed.

MEASUREMENT TYPE
The user may select from four different measurement methods: averaging, three-point
measurement single-point or multiple points measurement .
(See “Making measurements”, page 12).
Average measures pressure and volume flow averages from time period selected by the
user. The period can be changed when Averaging is selected and OK is pressed. The period
will start to blink. Desired time period (1…59 s) may now be selected using up and down
arrows. Selection is confirmed by pressing OK. Selected measurement method is shown in
bold text.
Three points takes three separate measurements of pressure and volume flow and the end
result is an average of the three measurements.
Single point uses instantaneous pressure and volume flow measurements.
DISPLAY SETTINGS
Backlight brightness and visibility of pressure and volume flow measurements can be
adjusted in the display settings.
Please note! To maximize the battery life of the device it is recommended to set the
backlight brightness to only as bright as the surroundings dictate. Typically, 20 % is bright
enough for all surroundings. This will make the battery life significantly longer.
Multiple points measurement allows pressure and flow measuring from the multiple
measuring points and the result is an average of the measured points (max. 15 points).

10
DATE
Date is set by pressing OK and changing values using the up and down buttons. Active
selection will blink on the screen. You may move to the next value by pressing right button
and to the previous by pressing left button. When the date is set, press OK to confirm.
CLOCK
Time is set by pressing OK and changing values using the up and down buttons. Active
selection will blink on the screen. You may move to the next value by pressing right button
and to the previous by pressing left button. When the time is set, press OK to confirm.
AUTO OFF
Auto Off will shut down the device automatically after it has been left unused for 10
minutes. Auto Off can be turned on or off by pressing OK.
TEMPERATURE
Temperature is set by pressing OK and adjusting with up and down buttons. Air density
changes with temperature, and therefore affects the volume flow calculation. K-values
usually apply under normal room conditions (temperature 20 °C). Changing the temperature
value the device will automatically compensate the volume flow calculation.
MEASUREMENTS
Old measurement savings can be viewed and deleted in the Measurements-menu. It is also
possible to toggle measurement saving on or off. There are three selections available in the
menu:
● RESULTS
● SAVING ON
● DELETE ALL

MEASUREMENTS
All previously recorded measurements are available for viewing in the Measurements menu.
The device will sort all records by date and time so that the oldest is first and latest is last.
Each recording contains the following information:
- space/room (for example, bathroom)
- valve type and size (for example KSO-100)
- K-factor
- volume flow and pressure
- valve opening
- temperature
Return back in menu by pressing the left arrow key.
SAVING ON
If recording is on, the device will ask after each measurement whether to record the
measurement. Recording can be switched on or off by pressing OK.
DELETE ALL
Delete all permanently erases all the records. Records are erased by pressing OK after which
the device will ask for confirmation. Select Yes if you are sure, otherwise select No.

MAKING MEASUREMENTS
Measuring chosen valve
Before commencing measuring the user has to set up units (Select units, pg. 8) and
measurement mode (Measurement mode, pg. 9)

When in K-factor measurement mode, the K-factor can be changed on display. K-factor
number is chosen by pressing left and right arrows and its value is changed using the up and
down arrows. When the desired K-factor is shown on display, the measurement is carried
out by pressing OK. Once measurement is completed, it will blink on display. If sliding aver-
age is selected, the measurement is the sliding average with the most recent measurement
calculated in it. In the case of the three-point measurement, the measurement is the average
of three measurements. With the blinking measurement on display, the device returns back
to measurement mode by pressing OK. If measurement recording has been enabled the
device will ask to record the measurement before returning to measurement mode.
MEASUREMENT USING CHOSEN VALVE
Different valves with different K-values can be saved to the device’s internal memory. By
selecting a valve, there is no longer need to remember separate K-factors, instead K-factor is
derived by other parameters. Before measuring a valve is chosen from the device’s memory.
There are two distinct measurement modes; measuring using K-factor and measuring using
chosen valve.
K-factor measurement the chosen measurement parameter is the K-factor. In valve measure-
ment, the K-factor is derived from the chosen valve and a parameter relating to, for example,
its opening value.

When a valve has been selected, valve parameter (f.e. valve opening) can be adjusted using
up and down arrow keys.
When the desired parameter is selected, the measuring can be carried out by pressing OK.
When the measuring is completed, the results of the measurement will blink on display. If
the measurement method is an average, the measurement result is an average of measure-
ments for the selected period (e.g. 5 sec). In three point measurement the number is the
average of three measurement points. When the measurement result is blinking on the
display, the device will return to the main mode by pressing OK. If the data recording is on,
the device will offer the option to save results before returning to the basic mode.
SAVING THE MEASUREMENT RESULTS
To save the results of measurement, the Save mode must be turned on. When measuring
with the device, the device will offer an option to save results. To save results, press Yes,
if not, press No. After this the device will ask for direction, choose between extract air or
supply air. Next choose the apartment number. Lastly, choose suitable room or space to be
measured. Measurement information can be browsed in the data storage menu.
