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

the supply air temperature from becoming too high or low.

Settings

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.

Settings

All setpoint settings for individual fans are found here

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.

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.

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.
