2.2 Description internal components
2.2.1 Fan
The fan has external rotor motors of EC type which are steplessly controlled. It is possible to program the speed in 2
steps (normal/reduced) depending on the programming of the week schedule. The motor bearings are life time lubri-
cated and maintenance free. It is possible to remove the fan for cleaning
2.2.2 Supply air filter
The filter is of bag filter type with filter quality ePM10 60% (M5). The filter need to be replaced when polluted. New fil-
ter can be acquired from your installer or wholesaler.
2.2.3 Pressure guard filters
A pressure guard measures the differential pressure over the supply air filter. When the pressure drop reaches the set
value an alarm is triggered in the main regulator. The differential pressure can be set between 40 and 300 Pa. The pres-
sure switch is preset from factory to 240 Pa.
2.2.4 Temperature sensor
In Topvex SF the supply air sensor is delivered with the unit and is to be installed in the supply air duct externally from
the unit. See Installation instructions for more detailed information.
The outdoor air sensor is mounted and wired inside the unit.

2.3 Heating battery
Warning
• Although the mains power supply to the unit has been disconnected there is still risk for injury due to
rotating parts that have not come to a complete standstill.
• Beware of sharp edges during maintenance. Use protective clothing.
• Observe that the heating battery can be hot although the power is switched of. Risk of burning.
2.3.1 Water heating battery
In units with built in water heating battery the hot water coil is located next to the supply air connection. The hot water
coil can be either HWL (hot water coil, low power) or HWH (hot water coil, high power). The coil material is copper pip-
ing with a frame of galvanized sheet steel and aluminium fins. The coil is equipped with venting and immersion sensor
for frost protection.
2.3.2 Electrical heater
In units with built in electrical heater the heating rods are located after the supply air fan in the airflow direction. The
material is stainless steel. The electric heating coil has both automatic and manual overheating protection.
The manual overheat protection is reset by pressing the button, marked RESET figure 1. The power demand of the elec-
trical heating coil is controlled by the main regulator.
The main regulator controls the heat steplessly by a TTC triac control according to the desired supply/extract or room
air temperature that is set in the control panel.
Topvex SF units equipped with Electrical heater performs 3 minutes of re-cooling after the unit have been turned of.
Note:
• If activating the fire alarm when the heater is switched on, the fan stops immediate without re-cooling,
this can cause the overheating protection to trip. See figure 1 where to reset.
• Reset of the overheat protection must be done by an authorized electrician.
• An all pole circuit breaker (safety switch) must precede the unit.

2.4 Electrical connection box, components
Danger
• Make sure that the mains power supply to the unit is disconnected before performing any maintenance
or electrical work!
• All electrical connections must be carried out by an authorized installer and in accordance with local rules
and regulations.
Caution
Be careful so the hatch doesn’t fall down if the unit is false ceiling mounted.
Topvex SF is equipped with a built in regulator and internal wiring.
Loosen the 4 screws to remove the hatch to the electrical connection box.

3.1 Control panel
The SCP control panel is delivered with a 10 m cable (up to 100 m can be used) that is connected to the panel and with
a fast coupling contact, connected to the Topvex unit. The contact is connected to the Corrigo controller in the electrical
connection box. The cable can be unscrewed in the back of the control panel (figure 2).

4.1 Before starting the system
When the installation is finished, check that:
• The unit is installed in accordance with the installation instructions
• The unit is correctly wired
• Mufflers are installed and that the duct system is correctly connected to the unit
• Outdoor air intake is positioned with sufficient distance to pollution sources (kitchen ventilator exhaust, central vac-
uum system exhaust or similar)
• All external equipment are connected
• The following data is available:
• Intended configuration, for example temperature control functions, fan control, external control functions etc.
• How the unit is supposed to operate according to a weekly schedule (normal and reduced speed)
4.2 Initial setup of the unit
On the first start-up, the controller will start a special program for setting language, supply air temp set point, Time &
date and week schedule for normal speed. Use the “OK” button to move between changeable parameters and the UP/
DOWN arrows to see the displayed alternatives. Confirm by pressing “OK” once more. Move on down in the menu
structure by use of the UP/DOWN arrows.
The following will be displayed:

4.4 Temperature control possibilities
Type of Control Temperature sensor placement Description/function
Supply air temperature control: The supply air temperature sensor is
placed in the supply air duct
approximately 3m after the unit.
Controls the temperature of the
supply air
Supply air temperature control with
outdoor air temperature
compensation:
2 temperature sensors are needed.
The outdoor air sensor is mounted
and wired inside the unit.
The supply air temp sensor is placed
in the supply air duct approximately
3m after the unit.
Compensates for low outdoor
temperatures by increasing the
supply air temperature with an
optional value to avoid sudden
temperature drops in the interior of
the building. Preset is + 20K
temperature increase at -20°C
outdoor temperature and +15K
increase at 0°C outdoor temperature.
Extract air temperature control: 2 temperature sensors are needed.
The extract air temp sensor is placed
in the extract air duct or in the room
if the building lacks extract air
ducting.
The supply air temp sensor is placed
in the supply air duct approximately
3m after the unit.
Set the extract air temperature
(preset is +18°C).
To ensure that the supply air
temperature produced by the unit is
not too low or too high, a minimum
and maximum supply air
temperature value can be set by the
installer/operator. Preset minimum
temperature is +12°C and maximum
temperature is +30°C.
