SAFETY CHECK
WARNING!
MAIN POWER SWITCH/ISOLATOR SWITCH
The eQ MASTER unit has an integrated main power switch in the electrical cabinet.
Access to the rotary switch is on the outside of the unit. Parts that are powered separately, such as electric heaters, require a
separate isolator switch.
Prior to servicing or inspection, the unit’s main power switch and all isolator switches must remain switched off for at least
1 minute before opening the inspection doors. Reset all safety devices before restarting.
The main power switch may not be used for normal starting and stopping of the unit. This must be done using the hand-held
terminal.
Before putting the air handling unit into operation, fit any unused connections with protective mesh.
In addition, all electrical and mechanical safety devices must be installed according to the eQ MASTER installation manual
before putting the air handling unit into operation.
Take extra care when opening the exhaust air valves for the hot water supplied to the air heater.
Risk of water hammer or steam discharge.
If the eQ MASTER is dismantled, FläktGroup will cease to be responsible for its compliance with the specified tightness class.
The unit’s doors are fitted with locking handles. Ensure that the unit is always left locked, and that the keys cannot be
accessed by unauthorized persons. Follow the separate instructions for replacement of casing parts.
Local rules and regulations must always be followed.
Read these instructions carefully before commissioning the unit.
The unit’s owner or the installation firm is responsible for ensuring that the relevant safety rules are followed.
No unauthorised persons may operate the unit. Only qualified staff members may use the unit.
Make sure that all the included parts and tools for installing the unit are removed before operating the unit.

SETTINGS/FUNCTIONS
If a function is not activated, its menus or settings will not be
visible. The same applies within the function, depending on which
sub-functions are activated. For instance, if only fan stage 1 is acti-
vated, fan stages 2 and 3 cannot be selected in other functions.
DAMPERS
Multiple dampers can be connected and controlled by the eQ
Master. The dampers are controlled either via Modbus or via IO.
No additional settings need to be configured for damper actua-
tors connected via Modbus. The settings are factory configured.
Settings for directly connected damper actuators (i.e. damper
actuators connected to IO by an installation engineer) are under
MAIN INDEX Ú UNIT Ú
DAMPER CONTROL
An Off delay time is configured here. This means the time the
damper waits before switching off after the fans are switched off.
An “Opening time” is specified under Dampers The opening time
is the operating time allowed in order for the damper to open. All
directly connected dampers have the same operating parameters.
In other words, the supply air damper and the extract damper have
the same parameters. If the selected damper actuators have diffe-
rent opening times, the longest time should be specified.
Supply air control
Supply air control is a temperature control function where the
supply air temperature is kept constant, with or without some type
of setpoint offset, without any data being sent from the room. This
control function is suitable in rooms where the heating and cooling
loads are relatively constant and predictable, or rooms with indivi-
dual room control.
Room control
Room control is available in two versions, either with or without
a cascade function. The room temperature is measured and the
supply air temperature is adjusted as necessary. The user sets
minimum and maximum limits for the supply air temperature.
If room control is used, two sensors can be used to control the
temperature based on an average value.
Extract air control
Extract air control is the same as the room control function above,
except instead of the room temperature being measured, the
primary sensor is installed in the extract air duct.
Heating-cooling
setpoint
Set the heating setpoint and cooling
setpoint as separate values.

TEMPERATURE
It generally applies to all temperature control that there are several
ways of setting the desired setpoint. When the temperature drops
below the heating setpoint, the heating sequence is activated, and
when it rises above the cooling setpoint the cooling sequence is
activated. When the actual temperature is within the dead zone,
all output signals that affect temperature will be zero. The compo-
nents that deliver cooling/heating are controlled in sequence in a
predetermined order, which is factory configured.

The settings for outdoor temperature compensation are under
Here you can choose the settings for either Summer compensation
or Winter compensation.
OUTDOOR TEMPERATURE CURVE
As an alternative to outdoor temperature compensation, the
temperature setpoint can be controlled by an outdoor temperature
curve with four break points.
The temperature remains constant above or below the curve’s
limits. The control setpoint changes linearly between the break
points. The heating and cooling setpoints are separated by an
adjustable dead zone, Cooling setpoint = Heating setpoint + Dead
zone.
Settings
The setpoint settings for the curve itself are under
The dead zone settings are one level up in the menu. The dead
zone settings cannot be configured if only heat recovery is availa-
ble as a cooling/heating stage.
COOLING RECOVERY TEMPERATURE
If the extract air temperature is lower than the outdoor air tempera-
ture and there is a demand for cooling, the heat recovery unit can
be started for full recovery. This saves energy by recovering cooling
energy from the extract air. The temperature difference between
the extract air and the outdoor air is set to 1 °C on delivery, but can
be changed under
SETTINGS/FUNCTIONS
Min./Max. limitation of supply air temperature
This is a subfunction of Room control and Extract air control. This
function limits the setpoint for the supply air temperature to prevent

OUTDOOR TEMPERATURE COMPENSATION
Outdoor temperature compensation is a function that adjusts the
setpoint according to the actual outdoor temperature. The compen-
sation can be either positive or negative depending on demand.

SETTINGS/FUNCTIONS
COOLING RECOVERY ENTHALPY
Cooling recovery enthalpy is a variant of standard cooling recovery.
This function requires humidity sensors in the outdoor and the
extract air. No settings are required.
FANS
Flow control
This is the standard function, which means that the control equip-
ment tries to keep the flow constant. This function should not be
used if the installation has dampers that could affect the duct
pressure.
Pressure control
This function keeps the duct pressure constant in the installation. It
requires a pressure sensor to be installed in the duct. This function
is suitable for IPSUM or similar VAV systems.
Slave control
If one of the fans is selected with slave function, that fan will be
controlled as a slave by the other fan. In other words, it will be
flow-controlled and will get its control setpoint from the other fan’s
actual flow value ± of offset. This function can be useful if one of the
fans is controlled by demand and the other fan always needs to
adjust accordingly to balance the flow.
Fan compensation
The fan setpoint can be affected by room temperature, air quality,
room humidity, outdoor temperature, a ReCooler device or as part
of the temperature sequence. The compensation can be positive or
negative according to user preference.

RECOVERY UNIT
Rotary heat recovery (hrec)
Check that the heat recovery unit runs smoothly and that the seals
are intact and tight. The heat recovery unit may need help starting
if its running direction has been changed. The heat recovery unit
should rotate so that when the wheel is downstream of the extract
air, it passes the purging sector before reaching the supply air.
Check that the pressure balance between the supply air and the
extract air is correct.
The pressure should be measured at nominal air flow in the ducts.
When the pressure is measured between P1 (-) and P2 (+) in the
picture, the pressure gauge should show a positive reading of 0-20
Pa for optimal functionality.
If the pressure difference is too large, the pressure in the supply
air duct should be increased, and if the difference is too small the
pressure in the extract air duct should be increased.
Frost protection
The rotary heat recovery unit can be equipped with various frost
protection systems if required.
SETTINGS/FUNCTIONS
Pressure Switch A pressure Pressure Switch (ON/OFF) that measures the pressure above the extract air on the rotor or an ex-
ternal thermostat in the duct can be used to detect frosting. The operating level for defrosting and the time delay
are set in the control system, while the temperature or pressure level is set on each individual sensor.
Temperature
A temperature sensor installed in the exhaust air stream limits the exhaust air temperature by restricting the output
signal to the recovery unit. An alarm function is also available which is triggered if the temperature drops too low.
The temperature limit and controller settings are configured in the control system.
Temperature and
Pressure Switch
A combination of both of the above.
Pressure sensor A pressure sensor (0–10V/Modbus) measures the pressure above the extract air on the rotor. When the desired
pressure is reached, the rotor speed decreases by one step, depending on the controller settings. The function
can be configured with I-time, D-time and an alarm limit for stopping the unit.
Pressure sensor
and Temperature
Pressure Switch
This is a combination of functionalities from the duct thermostat (monitor) and the pressure sensor specified
above. There is also an adjustable value for setting the max. rotor speed during defrosting.
Dew point A combined humidity/temperature sensor in the extract air stream measures actual extract air temperature
and humidity.
The actual dew point is calculated. The exhaust air temperature is calculated based on the supply air and
extract air flows, the outdoor and extract air temperatures and the actual rotor speed.
The exhaust air temperature is kept within the minimum limit by reducing the rotor speed so that it never falls
below the actual dew point plus a safety margin if this value is lower than 0 °C.
Only the safety margin needs adjusting.
Pre heating A pre-heating coil in the outdoor air can also be used to prevent frosting on the rotary heat recovery unit. The
frost detection function works according to the same principle as described above, except that instead of lim-
iting the recovery unit’s rotor speed, the pre-heating unit’s temperature setpoint is adjusted to prevent frosting.
Only the safety margin needs adjusting.

Heat recovery kick
The rotary heat recovery unit will remain idle for long periods during
the spring and autumn. At these times, the heat recovery unit
should be exercised in the same way as a pump or valve. This also
removes dirt and dust.

user is logged in as “Factory”.
Plate heat recovery unit
This type of recovery unit comes in two versions: one with cross
flow and one with counterflow. Both versions function according to
the same basic principle, and their power is controlled by opening/
closing a damper so that the air is either directed through or past
the heat recovery block and all combinations in between.
Several frost protection/defrosting functions are available for the
heat recovery unit, two of which are completely independent of the
unit’s controller.
SETTINGS/FUNCTIONS
Pressure Switch A pressure monitor (ON/OFF) that measures the pressure above the extract air on the rotor or an external
thermostat in the duct can be used to detect frosting. The operating level for defrosting and the time delay are
set in the display, while the temperature or pressure level is set on each individual sensor.
Temperature level 1 Defrosting “Cold corner”. A temperature sensor next to the “cold corner” measures the temperature and limits
the control signal to the recovery unit, to prevent the temperature dropping too low.
Temperature level 1
plus monitor
A combination of both of the above.
Pressure sensor A pressure sensor gauges the pressure drop above the heat recovery unit’s extract air unit. If the pressure rises
above the set value, the control signal to the recovery unit is reduced, which lowers the efficiency and prevents
further frosting.
If the pressure rises above the alarm limit value, the unit stops and an alarm is generated.

Level 2 Section defrosting. All the logic is in the recovery unit’s internal control system. The unit’s control system only
controls demand from 0-100 %.

ECOTERM coil heat recovery
The underlying functional principle is that warm extract air heats
the liquid in the extract air coil, which is then circulated by a pump
over the supply air coil, where the heat is released into the supply
air and the liquid is cooled.
Humidity in the extract air, low outdoor temperatures and high
efficiency cause frosting on the extract air coil.
SETTINGS/FUNCTIONS
Pressure Switch A pressure monitor (ON/OFF) that measures the pressure above the extract air on the rotor or an external
thermostat in the duct can be used to detect frosting. The operating level for defrosting and the time delay
are set in the display, while the temperature or pressure level is set on each individual sensor.
Temperature A temperature sensor in the liquid circuit that measures the inlet temperature into the extract air coil.
If this temperature drops below the set limit, the output signal to the pilot valve is reduced, which prevents
frosting. The temperature must be indicated in the display.

Dew point A combined temperature/humidity sensor in the extract air stream measures humidity and temperature.
The display calculates the actual dew point in the extract air based on these data. A temperature sensor
in the liquid circuit measures the inlet temperature to the extract air coil. The display calculates the lowest
liquid temperature that is permitted in relation to the actual dew point, and limits the temperature of the
liquid by reducing the output signal to the pilot valve.

AFTERTREATMENT
Up to three heating coils (Heating 1, 2 and 3) and three cooling coils
(Cooling 1, 2 and 3) can be used for aftertreatment in the eQ Master.
They can all be different, and heating and cooling coils can also
be combined into a combi coil. Heating 1 and Cooling 1 = Combi 1,
Heating 2 and Cooling 2 = Combi 2, Heating 3 and Cooling 3 cannot
be combined to make a Combi 3 coil. The different coils (max. 4 in
total) can be installed anywhere in the heating/cooling sequence.
Install them where they are most effective.
Settings
The settings for loop controllers and reading of actual values are
under (X = 1 to 3)
Heating coil water
A pilot valve controls the liquid temperature or the liquid flow to the
coil. The coil can be equipped with various types of frost protection
and pump control systems.
Frost monitor function
Settings
The setpoints for Frost monitor and Frost monitor 2 are under
There are no settings for Frost monitor in the display, so this
function must be adjusted manually on the sensor.
Electric heater
There is a power control function inside the electric heater. The
coils are controlled from 0-10 V or via Modbus from the control
system, according to demand in the sequence with the other
aftertreatments.
Frost monitor A temperature sensor in the liquid circuit measures the return temperature of the liquid from the coil.
The return temperature is controlled against the setpoint that has been set for the frost protection
controller. If the temperature drops below the lower limit value, the valve opens.
If the liquid drops below the alarm limit value, an alarm is generated and the unit stops.
Frost monitor 2 setpoint Same as above, except that there are two different setpoints for forced opening of the pilot valve,
depending on whether the unit is in operation or idle. Default setting.
Frost monitor det. A thermostat (ON/OFF) is either fitted in the airflow downstream of the coil or in the liquid return flow
from the coil. When the thermostat senses that the temperature is too low, an alarm is generated.
