Simple inspection and little maintenance The inside of the unit is easy to access through the grille. A dirty filter may lead to inadequate performance as well as an increase in noise level. Therefore, the filter must be cleaned regularly. The air filter (Class G1) is located behind the inlet and is easy to clean using a vacuum cleaner. Standard delivery and accessories The Comfort Circle comes standard with: • 2 suspension profiles • 2 blanking plates to adjust the discharge pattern • integrated condensate discharge pump (only with cooling) • external condensate drain tray (only with cooling)...

Control options The Comfort Circle is available with two control types: a standard (air-side) control and a modulating (air- and water-side) control. The control panel allows the user to easily set the indoor climate to a comfortable level. 1. Standard air-side control (S) This control regulates the fan speed (in 3 speed) to reach the desired room temperature. 2. Modulating air- and water-side control (M) This control regulates both the fan speed and the discharge air temperature to reach the desired room temperature. The ventilation unit is available only with this modulating control. Control...

Electronic control system The control panel and the PCB in the unit constitute the electronic control system. The two components are connected to one another using a low-voltage cable that has RJ11 plugs. The side of the cassette unit houses a connector plate, where all connections are made. Here, the controller and other units, if any, are plugged in. Also, any waterside controls and in- and outputs can be connected here. The outputs (max. 24V) can be used for, for instance, controlling the CH boiler or cooling units. Faults can be reported, too. To the input, a low-limit thermostat, a summer...
