All sensors and accessories are connected to TopMaster
via connections in the electrical cabinet. Cables to external components are secured in the electrical cabinet using
the tie-rail with a cable tie, for example.. The cable is then
placed against the cellular plastic strip on the unit (see
figure 1).
When all cables are connected to terminals and the
cables are secured on the tie rail, the cover is positioned
on the electrical cabinet and secured using the appropriate screws (see figure 2). The cellular plastic, which is
semi-elastic, will slowly adapt to the shape of the cables
and in doing so the lead-through will seal (see figure 3).
Information about how the different sensors and
accessories should be fitted and connected is provided in
the following section.

Control functions
• Continuously rotating heat exchangers
Room control and exhaust air control is the same
control type with the difference that in combination with
room control an external room sensor is needed (separate
ordering code). In addition it is possible to use outdoor
temperature compensation. This control mode cannot be
combined with extract air control or room control.
The unit is configured for supply air control as standard. To obtain other control modes, first the controller
must be changed from standard mode to cascade mode.
Then control mode is selected by changing the cascade
reference to extract air control/room control (0) or outdoor temperature compensation (1). Below is a description
of the different control modes.
Choice of cooling
Supply air control
1. Rotor, heating and cooling
The unit is configured differently with regard to heating,
heat recovery and cooling, see below.
Choice of heating function
• No heater
• Electric heater
• A water heater with frost-guard function
Heat recovery
• No cooling
To maintain a constant supply air temperature, the controller works from a fixed setpoint and the supply air
temperature. Based on these parameters, the controller
controls the current heating, heat recovery and cooling
sequences.
• Water -cooling
• DX cooling, 1-stage
Control function
The control function works as follows:
Regardless of control mode the unit tries to achieve the
desired setpoint.
This is done by the unit depending on the needs,
demand for heat recovery, heating or cooling. Built into
the system is also a dead zone. The dead zone function
(usually 2°C) acts as a temperature zone between heat
recovery and cooling unit where neither calls for heat recovery or cooling.
The reason for having a dead zone, is that the temperature will be slightly lower in winter, and slightly higher
in summer. This is energy-efficient and in practice even
more convenient for people staying in the room.
Control signal, %
Sequence control
Extract air control
The exhaust air temperature gives a good average value
of the temperature in different rooms. Using this the
unit controls the supply air temperature to maintain the
extract temperature at a desired level.
This method is suitable for ventilation systems that
supply a number of similar rooms. In cases where different rooms have different heating requirements, this
method should not be used. This is because the unit cannot detect the varying heating needs, but can only read
an average temperature.
The limits on the supply air temperature (min. temp.
/ max. temp.) ensure that the supply air temperature is
maintained within the set range.

Figure 1. The figure shows the controller’s output signals to the

figure also shows two temperatures, one for heating (T2)
and one for cooling (T3). The zone between T2 and T3 is
called the dead zone. Note that heating is activated only
when heat recovery is working at 100%.
2. Temperature controls
TopMaster has three temperature control options, supply
air, extract air control and room control.

Sets lowest supply air
temperature
Sets highest supply air
temperature
Example
1. Setpoint = 18°C
2. Extract air temperature = 16°C
This means that the new calculated setpoint for the
supply air controller is:
Calculated setpoint = setpoint + (setpoint – exhaust air
temperature) x cascade A = 18 + (18-16) x 0.5 = 19 ° C.
Control functions (cont.)
Room control
Room control gives the best control of temperature in a
specific room and is used when only one unit serves this
room. This method works best for larger premises.
By replacing the exhaust temperature sensor with a
room temperature sensor placed in the room in question,
a good room temperature value is achieved.
This enables the unit to regulate the supply air temperature in a way that maintains the room temperature at a
desired level.
Limitation of the supply air temperature (min. temp.
and max. temp.) ensures that the supply air temperature
is maintained within the set range.
Default parameters for room control
1. Controller = 2
Selects cascade control
3. Cascade A = 0.5
4. Cascade B = –0.5 Selects room control
5. Min. temp. = 15°C
temperature
Sets highest supply air temperature
Example
1. Setpoint = 18°C
2. Room temperature = 22°
This means that the new calculated setpoint for the supply air controller is:
Calculated setpoint = setpoint + (setpoint – room air temperature) x cascade B = 18 – (18 – 22) x (–0.5) = 16°C.
Outdoor temperature compensation
The setpoint temperature for supply air can be adjusted
up or down depending on the outdoor temperature. By
setting a higher set point value both on cold winter days
and hot summer days indoors comfort is improved.
In summer, this will increase energy savings. Outdoor
temperature compensation can not be combined with extract air control or room control.
Default parameters for outdoor temperature

Outdoor temperature, °C
Example 1
1. Setpoint = 18°C
2. Outdoor air temperature = –2°C
Calculated setpoint = setpoint + (setpoint – outdoor air
temperature) x cascade A = 18 + (18 –(-2)) x 0.05 = 19°C
Example 2
1. Setpoint = 18°C
2. Outdoor air temperature = 28°C
Calculated setpoint = setpoint + (setpoint – outdoor air
temperature) x cascade B = 18 – (18 – 28)) x 0.30 = 21°C.
3. Freeze protection
Warning! Do not change these parameters unless it is
absolutely necessary. If the unit is misconfigured the
water coil can freeze up and cause water damage to
property.
Freeze protection is used during low outdoor temperatures to prevent the coil from freezing. When the unit
is stopped, the temperature in the water coil is maintained at the setpoint to keep the unit warm. If there is a
risk of freezing in the water coil the motorized valve is
controlled to open.
If the temperature drops below the adjustable limit
value an A-alarm is obtained, which then stops the unit.
4. Defrost function
The defrost function is used to prevent the rotor from
freezing. By measuring the pressure across the rotor it is
possible to verify when the rotor needs to be defrosted.
When the pressure over the rotor becomes too high it
activates a time delay before defrosting. Then defrosting
starts. When the pressure is below the given limit value it
starts a time delay. When the time delay has elapsed, the
defrosting stops
Defrosting is achieved by running the rotor sectionwise. Fan speeds are not affected.
Control functions (cont.)
5. Cooling recovery
Cooling energy recovery is used when cooling load is
needed by taking advantage of any room cooling. Cooling recovery is activated if the outdoor temperature is 2°
C higher than the extract air temperature and the unit is
operating in “summer mode”. If this condition is satisfied
the rotor starts and supplies 100%.
6. Night cooling
Night cooling is used in summertime to reduce cooling
load at unit start-up and to limit the maximum temperature during non-working hours. This is done by making
use of cold outside air during cool summer nights.

Room setpoint
Pressure control regulates air pressure in index duct (duct
with a maximum pressure drop, and where the static pressure is lowest). The pressure sensor (GP3) is placed at the
beginning of this duct The exhaust sensor (GP4) is placed
in the exhaust duct at a suitable location with representative pressure. For settings see the Parameter list.
2.Outdoor temperature < Extract temperature – Delta.
If the above conditions are met the night cooling
starts. 3. The following take place during night cooling
a. Rotor, afterheater and any cooling are blocked.
b. The fans are switched to the high speed setting.
The measuring pressure, Dpm, is the difference between
the pressure in the empty section at the fan inlet and the
pressure inside the inlet cone.
The pressure sensor is connected via two externally
placed measuring nipples.
Value of the constant (k) is shown in the table below.
For settings see the parameter list.

The sensors must be zeroed during commissioning. They
should then be zeroed annually. The sensors should have
been energized for approximately one hour before calibration is carried out. After that, remove the hoses from
the sensors. To start calibration press the push-button
next to the pressure range jumpers. The red LED lights
up and goes out after about a second. Reassemble the air
hoses. Done!
