Electrical heater
The heating coil is located after the supply fan (fig. 3) and the material is stainless steel. The electric
heating coil has both automatic and manual overheating protection. The power demand of the electric
heating coil is controlled by an on/off function according to the desired supply or extract air
temperature that is set in the control panel.
Hot water heater
The hot water coil is located after the supply fan (fig. 3). The coil is mounted for easy connection
through the top of the unit (fig. 1 and 2). At the same time, it is designed in such a way that it is easy
to access the pipe connections. The material is copper piping with a frame of galvanized sheet steel
and aluminum fins. The coil has an immersion sensor as frost guard. If the temperature drops and
there is a risk of freezing (outlet water temperature below 8°C) the water flow is maintained (the valve
will open fully), the fans stops and the outdoor/exhaust air damper, accessory, closes
instantaneously. As an alternative the supply air temperature can control the frost protection. The
alarm limit (°C) is to be set in the control panel.
Fig. 4 shows two possible solutions for designing the water regulation.
Control panel
The SCP control panel is delivered with a 10m cable that is pre-connected to the panel and with a fast
coupling ISDN contact, pre-connected to the Topvex unit. The ISDN contact is connected to the
Corrigo controller in the electrical connection box (fig. 3). The cable can be unscrewed in the back of
the control panel (fig 5).
General information is shown in (fig 5).
How to operate
The menus in the Corrigo E are organized in a horizontal tree structure. The UP/DOWN-buttons are
used to move between menus at the present menu level. The RIGHT/LEFT buttons are used to move
between menu levels. When changing parameters the UP/DOWN buttons are used to
increase/decrease the value of the parameter and the RIGHT/LEFT buttons to move between digits
within the parameter.
The OK button is used to confirm the choice of a parameter setting.
The C button is used to abort an initiated parameter change and restore the original value.
The ALARM button is used to access the alarm list.
Changing parameters
In some menus there are parameters that can be set. This will be indicated by the LED flashing.
To change a parameter, first press the OK button, the LED changes to a steady light. A cursor
will appear at the first settable value. If you wish to change the value, do so by pressing the
UP/DOWN buttons. In numbers containing several digits you can move between the digits using the
LEFT/RIGHT-buttons.
When the desired value is displayed presses OK. If there are further settable values displayed the
cursor will automatically move to the next one. To pass a value without changing it, press RIGHT.
To abort a change and return to the initial setting, press and hold the C-button until the cursor
disappears.
