2. Mounting Opus
2.1 Installation of the control panel
The control panel is designed to be fitted in the opening of
an Opus type plug socket.
2.2 Mounting
Find the location where the control panel is to be placed
and connect the lead first then click the control panel in
place.
A low-current cable 8 x 0.25 mm2 must be attached
between the unit and the control panel. 50 m is the
maximum cable length. The voltage drop for cable
lengths over 50 m is too high and can result in unreliable
operation.
Check that the cable is connected to the same numbers at
both ends. (Between the control panel and the main circuit
board in the unit.)
The button to the left of the control panel is B3 and the
button on the right is B5. B4, which we know from the
Design control panel is, in the case of Opus, just used to
hold both buttons down, i.e. B3 and B5 together.
3. Operation
All Genvex GE/S Energy and GEU residential ventilation
units can be operated with the Optima 100 control.
The Optima 100 control has the following settings:
Ventilator speed, filter alarm, bypass ON/OFF and
electrical heating ON/OFF.
The control unit is supplied with factory set settings that
enable the unit to be operated without initially having to
change the settings. The factory settings are only basic
settings, which can be changed to suit the operational
requirements and needs of the building, so that the system
can be optimally used and operated.
3.1 Use and changing of the settings
Optima 100 Design is operated via the B3, B4 and B5
buttons. Optima 100 Opus is operated via the B3 and B5
buttons. With Opus the B4 button enables the B3 and
B5 buttons to be held down at the same time. The button
combinations that need to be used to change the ventilator
speed, reset the filter alarm and switch on/off the bypass
and/or electrical heating are described below.
